From c1b0265ac84e5dcdb1d60b5df50b14ebcbf41344 Mon Sep 17 00:00:00 2001 From: Tongwei Dai Date: Wed, 8 Apr 2026 00:10:11 -0700 Subject: [PATCH 01/25] Fix stale bind group reuse after renderer/stage switch MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The frame graph's bind group cache used per-name version counters (starting at 1 on creation), so two distinct textures like "wireframe/color" and "pathtracer/color" could share the same version — causing the cache to falsely match and reuse a bind group pointing to the wrong GPU resource. External resources (IBL views, samplers) had no version tracking at all (always 0), so switching stages left stale IBL texture views in cached bind groups. Fix: replace per-name counters with a global monotonic version counter on FrameGraph, and fingerprint external resources by pointer identity. Also clear stale texture refs in create_renderer() as a defensive measure. --- core/include/core/rendering/frameGraph.h | 7 +++++ core/src/rendering/frameGraph.cpp | 33 ++++++++++++------------ editor/src/editorApplication.cpp | 2 ++ 3 files changed, 25 insertions(+), 17 deletions(-) diff --git a/core/include/core/rendering/frameGraph.h b/core/include/core/rendering/frameGraph.h index feece49..8cc0705 100644 --- a/core/include/core/rendering/frameGraph.h +++ b/core/include/core/rendering/frameGraph.h @@ -340,6 +340,13 @@ class FrameGraph { enum class ResourceKind { Texture, Buffer, BindGroup }; std::string make_pass_key(const IPass* pass, const char* label, ResourceKind kind); + + /// Monotonic counter — every new or recreated cached resource gets the + /// next value, so no two distinct GPU resources ever share a version. + uint64_t m_next_version = 1; + uint64_t next_version() { + return m_next_version++; + } }; } // namespace pts::rendering diff --git a/core/src/rendering/frameGraph.cpp b/core/src/rendering/frameGraph.cpp index 12fdfaa..e7dfe44 100644 --- a/core/src/rendering/frameGraph.cpp +++ b/core/src/rendering/frameGraph.cpp @@ -565,7 +565,7 @@ void FrameGraph::allocate_textures() { cached->view = view; cached->desc = res.desc; cached->used_this_frame = true; - cached->version = prev_version + 1; + cached->version = next_version(); // Create per-layer views for array textures if (use_array_view) { @@ -599,19 +599,14 @@ void FrameGraph::allocate_buffers() { continue; } - // Different pointer or new entry — bump version - uint64_t prev_version = 0; - if (it != m_buffer_cache.end()) { - prev_version = it->second->version; - } - + // Different pointer or new entry auto cached = boost::intrusive_ptr(new detail::CachedBuffer()); cached->buffer = res.external_buffer; cached->desc.size = res.external_size; cached->desc.usage = WGPUBufferUsage_None; cached->owned = false; cached->used_this_frame = true; - cached->version = prev_version + 1; + cached->version = next_version(); m_buffer_cache[res.name] = cached; m_logger->debug("FrameGraph: imported buffer '{}' (size={})", res.name, @@ -626,10 +621,8 @@ void FrameGraph::allocate_buffers() { continue; } - // Need new buffer — capture previous version before evicting - uint64_t prev_version = 0; + // Need new buffer if (it != m_buffer_cache.end()) { - prev_version = it->second->version; m_buffer_cache.erase(it); } @@ -644,7 +637,7 @@ void FrameGraph::allocate_buffers() { cached->desc = res.desc; cached->owned = true; cached->used_this_frame = true; - cached->version = prev_version + 1; + cached->version = next_version(); m_buffer_cache[res.name] = cached; m_logger->debug("FrameGraph: created buffer '{}' (size={})", res.name, res.desc.size); @@ -656,7 +649,10 @@ void FrameGraph::allocate_bind_groups() { for (auto& res : m_bg_resources) { auto& desc = res.desc; - // 1.

charset=UTF-8 Content-Transfer-Encoding: 8bit Add ContactShadowPass: fullscreen ray march against the depth buffer toward each light, producing a per-pixel shadow factor (R8Unorm). The forward shader reads it via bind group 3 and modulates direct lighting only (not IBL/emissive). Introduce light_iteration.slang abstracting the "for each light" loop — both forward.slang and contact_shadow.slang use it. When clustered lighting lands, only this module changes. Includes 64-light test scene (clustered_lighting_test.usda) for development and stress testing. --- assets/scenes/clustered_lighting_test.usda | 267 ++++++++++++++++ config.yaml | 9 + .../core/rendering/contactShadowPass.h | 74 +++++ core/shaders/contact_shadow.slang | 120 ++++++++ core/shaders/light_iteration.slang | 11 + core/shaders/lighting.slang | 6 +- core/src/rendering/contactShadowPass.cpp | 227 ++++++++++++++ core/tests/CMakeLists.txt | 4 + core/tests/testContactShadowPass.cpp | 290 ++++++++++++++++++ editor/src/editorApplication.cpp | 5 + renderers/forward/forward.slang | 21 +- renderers/forward/forwardPass.cpp | 115 ++++++- renderers/forward/forwardPass.h | 5 + 13 files changed, 1145 insertions(+), 9 deletions(-) create mode 100644 assets/scenes/clustered_lighting_test.usda create mode 100644 core/include/core/rendering/contactShadowPass.h create mode 100644 core/shaders/contact_shadow.slang create mode 100644 core/shaders/light_iteration.slang create mode 100644 core/src/rendering/contactShadowPass.cpp create mode 100644 core/tests/testContactShadowPass.cpp diff --git a/assets/scenes/clustered_lighting_test.usda b/assets/scenes/clustered_lighting_test.usda new file mode 100644 index 0000000..b87dbb7 --- /dev/null +++ b/assets/scenes/clustered_lighting_test.usda @@ -0,0 +1,267 @@ +#usda 1.0 +( + defaultPrim = "Root" + upAxis = "Y" +) + +def Xform "Root" +{ + #

charset=UTF-8 Content-Transfer-Encoding: 8bit Replace all manual WGPUBindGroupLayoutEntry arrays with declarative OutputSlot descriptions. One declaration creates the layout at setup and fills the descriptor per-frame. Sampler slots auto-filled from format. Rename BindGroup → Descriptor throughout (no compat aliases). Add PassBuilder.descriptor() for static descriptor auto-set before execute. FallbackPool provides shared 1x1 fallback textures. Child passes own their consumer descriptors via OutputLayoutInfo. GBuffer gains consumer output for downstream passes. --- .../core/rendering/contactShadowPass.h | 14 +- core/include/core/rendering/fallbackPool.h | 51 ++ core/include/core/rendering/frameGraph.h | 104 ++- core/include/core/rendering/gbufferPass.h | 12 +- core/include/core/rendering/iblResources.h | 16 +- core/include/core/rendering/outputLayout.h | 160 +++++ core/include/core/rendering/renderPass.h | 10 +- core/include/core/rendering/shadowMapPass.h | 8 +- core/include/core/rendering/ssaoPass.h | 4 +- core/include/core/rendering/toneMappingPass.h | 4 +- core/src/rendering/contactShadowPass.cpp | 122 ++-- core/src/rendering/fallbackPool.cpp | 126 ++++ core/src/rendering/frameGraph.cpp | 186 +++-- core/src/rendering/gbufferPass.cpp | 68 +- core/src/rendering/iblResources.cpp | 249 +++---- core/src/rendering/outputLayout.cpp | 247 +++++++ core/src/rendering/shadowMapPass.cpp | 78 ++- core/src/rendering/ssaoPass.cpp | 204 ++---- core/src/rendering/toneMappingPass.cpp | 185 ++--- core/tests/testContactShadowPass.cpp | 6 +- core/tests/testFrameGraph.cpp | 643 ++++++++++++++---- editor/src/passes/editorPass.cpp | 77 +-- editor/src/passes/editorPass.h | 4 +- editor/src/passes/gridPass.cpp | 28 +- editor/src/passes/gridPass.h | 2 +- editor/src/passes/lobePass.cpp | 49 +- editor/src/passes/lobePass.h | 2 +- editor/src/passes/wireframePass.cpp | 47 +- editor/src/passes/wireframePass.h | 2 +- editor/tests/testAutoExposure.cpp | 10 +- renderers/forward/forwardPass.cpp | 435 +++--------- renderers/forward/forwardPass.h | 16 +- renderers/pathtracer/pathTracerPass.cpp | 179 ++--- renderers/pathtracer/pathTracerPass.h | 6 +- 34 files changed, 1999 insertions(+), 1355 deletions(-) create mode 100644 core/include/core/rendering/fallbackPool.h create mode 100644 core/include/core/rendering/outputLayout.h create mode 100644 core/src/rendering/fallbackPool.cpp create mode 100644 core/src/rendering/outputLayout.cpp diff --git a/core/include/core/rendering/contactShadowPass.h b/core/include/core/rendering/contactShadowPass.h index dc9b319..6427a26 100644 --- a/core/include/core/rendering/contactShadowPass.h +++ b/core/include/core/rendering/contactShadowPass.h @@ -1,6 +1,7 @@ #pragma once #include +#include #include #include #include @@ -11,6 +12,7 @@ namespace pts::rendering { +class FallbackPool; class ShaderLoader; /// Screen-space contact shadow pass. @@ -42,12 +44,17 @@ class ContactShadowPass final : public IPass { }; struct Outputs { ResourceHandle contact_shadow; + DescriptorHandle consumer_desc; }; void do_setup(const webgpu::Device& device) override; - Outputs add_to_frame_graph(FrameGraph& fg, const PassContext& ctx, const Inputs& in); + Outputs add_to_frame_graph(FrameGraph& fg, const PassContext& ctx, const Inputs& in, + FallbackPool& fallbacks); void draw_imgui() override; + /// Layout for the consumer bind group (CS texture + sampler).

charset=UTF-8 Content-Transfer-Encoding: 8bit Typestate design: separate Decl (declaration phase, no GPU handles) and compiled (GPU handles valid, accessed via ExecuteContext::get(handle)) types. Declaration-phase invalid state is unrepresentable. Handles are strong-typedef uint32_t indices into dense vectors. No unordered_map+unique_ptr for hot-path access — O(1) handle indexing, cache-friendly iteration. Strings are debug labels only, never used as hot-path lookup keys. FrameGraph owns: - Textures, buffers, descriptors (Frame/Persistent lifetime) - Samplers (deduplicated pool) - Shader modules (cached with hot-reload invalidation) - Render/compute pipelines (fingerprint-based caching, shader-version invalidation) - Bind group layouts - Persistent uploads (LTC tables, SSAO kernel/noise, IBL fallbacks) Pass interface: - ensure_initialized(device) replaces do_setup/is_ready - Passes cache handles as plain members, register once (first frame) - No per-frame string allocations for registered resources - Implicit liveness via PassBuilder/DescriptorBuilder usage Compiled resource safety: - ExecuteContext::get() asserts valid handle, current-frame liveness, and non-null compiled pointer - Deferred destruction on desc change / eviction keeps pre-compile references (e.g. ImGui draw data) valid through execute Removed: - OutputLayoutInfo, auto-sampler creation, BuildResource - TextureHandle/BufferHandle/DescriptorHandle (old indices) - TextureRef/BufferRef/DescriptorRef, ResourceRef - CachedResource, intrusive_ptr refcounting - LtcTextures class (textures + sampler in FG static cache) - All Ready structs, do_setup/do_renderer_setup, variant - Declaration vectors (m_resources/m_buffer_resources/m_descriptor_resources) - allocate_textures/allocate_buffers/allocate_descriptors - unordered_map> storage for decls Cross-pass coupling (SSAO/ContactShadow → GBufferPass*) removed via static consumer_slots(). --- .../core/rendering/contactShadowPass.h | 41 +- core/include/core/rendering/frameGraph.h | 696 ++++-- core/include/core/rendering/gbufferPass.h | 33 +- core/include/core/rendering/iblResources.h | 3 +- core/include/core/rendering/ltcTextures.h | 45 - core/include/core/rendering/outputLayout.h | 50 +- core/include/core/rendering/renderPass.h | 42 +- core/include/core/rendering/renderWorld.h | 4 +- core/include/core/rendering/renderer.h | 21 +- core/include/core/rendering/shadowMapPass.h | 30 +- core/include/core/rendering/ssaoPass.h | 42 +- core/include/core/rendering/toneMappingPass.h | 40 +- .../core/rendering/webgpu/pipelineBuilder.h | 2 + core/src/rendering/contactShadowPass.cpp | 137 +- core/src/rendering/frameGraph.cpp | 1867 ++++++++++++----- core/src/rendering/gbufferPass.cpp | 133 +- core/src/rendering/iblResources.cpp | 43 +- core/src/rendering/ltcTextures.cpp | 158 -- core/src/rendering/outputLayout.cpp | 188 +- core/src/rendering/renderPass.cpp | 58 +- core/src/rendering/renderWorld.cpp | 5 +- core/src/rendering/shadowMapPass.cpp | 158 +- core/src/rendering/ssaoPass.cpp | 269 +-- core/src/rendering/toneMappingPass.cpp | 277 +-- core/src/rendering/webgpu/pipelineBuilder.cpp | 10 + core/tests/testContactShadowPass.cpp | 75 +- core/tests/testDomeIbl.cpp | 39 +- core/tests/testFrameGraph.cpp | 1768 ++++------------ core/tests/testIblResources.cpp | 23 +- core/tests/testMeshCache.cpp | 5 - core/tests/testRendererRegistry.cpp | 19 +- core/tests/testShadowMapPass.cpp | 76 +- editor/src/editorApplication.cpp | 185 +- editor/src/include/editorApplication.h | 6 +- editor/src/passes/editorPass.cpp | 276 +-- editor/src/passes/editorPass.h | 21 - editor/src/passes/gridPass.cpp | 96 +- editor/src/passes/gridPass.h | 17 +- editor/src/passes/lobePass.cpp | 178 +- editor/src/passes/lobePass.h | 21 +- editor/src/passes/wireframePass.cpp | 107 +- editor/src/passes/wireframePass.h | 15 - editor/src/perfOverlay.h | 3 +- hello_triangle/src/main.cpp | 6 +- renderers/forward/forwardPass.cpp | 640 +++--- renderers/forward/forwardPass.h | 29 - renderers/pathtracer/pathTracerPass.cpp | 255 +-- renderers/pathtracer/pathTracerPass.h | 22 +- 48 files changed, 3538 insertions(+), 4696 deletions(-) delete mode 100644 core/include/core/rendering/ltcTextures.h delete mode 100644 core/src/rendering/ltcTextures.cpp diff --git a/core/include/core/rendering/contactShadowPass.h b/core/include/core/rendering/contactShadowPass.h index 7ebea2b..3080b8b 100644 --- a/core/include/core/rendering/contactShadowPass.h +++ b/core/include/core/rendering/contactShadowPass.h @@ -3,17 +3,14 @@ #include #include #include -#include -#include #include +#include #include -#include namespace pts::rendering { class FallbackPool;

charset=UTF-8 Content-Transfer-Encoding: 8bit String-keyed caches (name→handle registries, shaders, BGLs, pipelines) now use boost::unordered_flat_map with transparent StringViewHash/Equal — lookups pass string_view directly and no longer allocate a std::string per find(). Pipeline builders gain a shader-version fast path: on a cache hit with matching shader_version, build() returns the cached pipeline without computing the full config fingerprint. Fingerprint is still checked on the slow path (shader invalidated or first build). Tracy zones added to FrameGraph hot-path methods (texture/buffer/descriptor registration, bind_group_layout, shader, sampler, add_pass, resize, import_buffer, descriptor factory, begin_frame) and to compile sub-phases (materialize_textures/buffers/descriptors, evict_unused).

DepTrackedCache (was 582133a) - Generic dep-tracked cache with forced-dirty invalidation and stable references; unifies FG/RenderWorld version tracking. IShaderCompiler interface + EmbeddedCompiler (was ec439d0) - Polymorphic shader-compilation interface; EmbeddedCompiler serves pre-built embedded WGSL, used on WASM and as native error-fallback. SlangCompiler backend (was 504d5bf) - libslang backend with on-disk cache and mtime-based poll_dirty. - Per-source-key mutexes for thread-safe compile. - Drops PTS_SHADER_HOT_RELOAD plumbing; editor polls the compiler. Config-driven shader variants (was 88cb87e, a51c818) - slangc.shaders[] gains a variants: list with defines + filename suffix. - shader_variants_codegen emits a constexpr (defines_canon -> suffix) map consumed by EmbeddedCompiler. - shader_variants_codegen fails loud on non-dict entries; unit tests cover conflicting-suffix detection and implicit-base handling. Cleanup (this ticket) - Rename headers/sources to lowerCamelCase per project convention: depTrackedCache.h, shaderCompiler.{h,cpp}, slangCompiler.{h,cpp}. - Drop the hand-rolled SHA-256 in slangCompiler.cpp in favor of boost::hash_combine over the cache-key inputs. Cache keys are not security-sensitive; collision resistance among same-process inputs is what matters, and format_version + defines + source + dep hashes make collisions astronomically unlikely. - Introduce ShaderKey { source, defines } flowing through IShaderCompiler::compile, SlangCompiler / EmbeddedCompiler, and FrameGraph's shader/shader_variant entry points. Provides hash_value / operator== so it can be used as a map key directly. Future variant axes (pso, material, vertex layout) become one-field changes rather than API churn. - Rename PTS_UNUSED -> UNUSED in diagnostics.h to match the rest of the macro surface; replace (void) silencers in depTrackedCache and testSlangCompiler. --- CLAUDE.md | 2 +- CMakeLists.txt | 3 +- config.yaml | 22 +- core/include/core/cache/depTrackedCache.h | 204 ++++++ core/include/core/diagnostics.h | 2 +- core/include/core/rendering/frameGraph.h | 101 +-- core/include/core/rendering/renderPass.h | 18 +- core/include/core/rendering/renderWorld.h | 45 +- core/include/core/rendering/renderer.h | 1 - core/include/core/rendering/shaderCompiler.h | 110 +++ core/include/core/rendering/shaderLoader.h | 70 +- core/include/core/rendering/slangCompiler.h | 67 ++ core/src/imgui/fileDialogue.cpp | 2 +- core/src/rendering/frameGraph.cpp | 674 +++++++++--------- core/src/rendering/renderPass.cpp | 21 +- core/src/rendering/renderWorld.cpp | 58 +- core/src/rendering/sceneLoader.cpp | 2 +- core/src/rendering/shaderCompiler.cpp | 149 ++++ core/src/rendering/shaderLoader.cpp | 460 +----------- core/src/rendering/slangCompiler.cpp | 503 +++++++++++++ core/src/rendering/webgpu/errorScope.cpp | 2 +- core/tests/CMakeLists.txt | 10 + core/tests/testContactShadowPass.cpp | 7 +- core/tests/testDepTrackedCache.cpp | 241 +++++++ core/tests/testFrameGraph.cpp | 30 +- core/tests/testMeshCache.cpp | 18 +- core/tests/testRenderWorldSlotMap.cpp | 8 +- core/tests/testShaderLoader.cpp | 53 +- core/tests/testShadowMapPass.cpp | 13 +- core/tests/testSlangCompiler.cpp | 217 ++++++ core/tests/testWorker.cpp | 4 +- editor/src/editorApplication.cpp | 31 +- editor/src/include/editorApplication.h | 2 + editor/src/main.cpp | 2 +- renderers/forward/forwardPass.cpp | 16 +- renderers/pathtracer/pathTracerPass.cpp | 5 +- renderers/pathtracer/pathTracerPass.h | 1 + tools/repo_tools/shader_variants_codegen.py | 182 +++++ tools/repo_tools/slangc.py | 78 +- .../tests/test_shader_variants_codegen.py | 91 +++ 40 files changed, 2492 insertions(+), 1033 deletions(-) create mode 100644 core/include/core/cache/depTrackedCache.h create mode 100644 core/include/core/rendering/shaderCompiler.h create mode 100644 core/include/core/rendering/slangCompiler.h create mode 100644 core/src/rendering/shaderCompiler.cpp create mode 100644 core/src/rendering/slangCompiler.cpp create mode 100644 core/tests/testDepTrackedCache.cpp create mode 100644 core/tests/testSlangCompiler.cpp create mode 100644 tools/repo_tools/shader_variants_codegen.py create mode 100644 tools/repo_tools/tests/test_shader_variants_codegen.py diff --git a/CLAUDE.md b/CLAUDE.md index 742f975..e04ba1e 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -70,7 +70,7 @@ Scene passes can declare debug MRT outputs (Normals, Base Color, etc.) via `debu - `effective_debug_target_names()` returns the gated count; the editor UI and frame graph use this - `load_pass_shader(resource_key)` automatically selects the no-debug shader variant when targets are disabled — passes just call this instead of `ShaderLoader::load()` directly - The no-debug variant is compiled at build time with `-DNO_DEBUG_TARGETS` (see `config.yaml` slangc entries with `defines:`) -- At runtime in hot-reload builds, `ShaderLoader::load_variant()` recompiles via Slang with the define; non-hot-reload builds fall back to the pre-compiled embedded WGSL +- On native, `SlangCompiler` recompiles via libslang with the define and caches the WGSL on disk (`/shader_cache/`); on WASM the `EmbeddedCompiler` serves the pre-compiled embedded variant. **Shader convention:** guard debug MRT struct fields and writes with `#ifndef NO_DEBUG_TARGETS`.

Architecture - core/shaderc/ — new CMake target `core::shaderc`. Houses slangRuntime, slangReflection, slangMetadata, ShaderLoader, and diagnostics.h. Main core library links it; builds slang-free on Emscripten so diagnostics.h and ShaderLoader remain accessible there. - tools/pts_shaderc/ — plain CMake tool (no Conan wrapper). Links only core::shaderc, avoiding the Dawn/ImGui/USD dep tree. `compile` and `batch` subcommands. - tools/repo_tools/slangc.py — reduced to a thin driver invoking pts_shaderc for config resolution and variant enumeration. - shader_codegen.py, shader_metadata.h.j2, and *.reflect.json all deleted. Runtime - IPass and 4 direct-call sites (hello_triangle, testWebGpu, testPipelineBuilder, testAutoExposure) route through IShaderCompiler::compile() instead of get_resource. - Native WGSL embedding scoped to Emscripten only; native builds rely on SlangCompiler at runtime. editor.exe shrinks -207 KB, embedded_resources.h 796 KB -> 30 KB. Build infra - tools/docker/linux-tools.Dockerfile + build-tools.sh for local Linux tool-build iteration. - linux-ci: Emscripten job builds host tools natively on its own Linux runner instead of consuming Windows artifacts. - Slang bumped 2026.1 -> 2026.5.2 for the reflection API + wgsl depth texture fixes. --- .github/workflows/ci.yml | 26 +- CLAUDE.md | 21 +- CMakeLists.txt | 11 +- allowlist_extra.toml | 4 + conan_emscripten.lock | 2 +- conan_glfw.lock | 4 +- conanfile.py | 5 +- config.yaml | 116 ++--- core/CMakeLists.txt | 2 + core/include/core/cache/depTrackedCache.h | 7 +- core/include/core/rendering/frameGraph.h | 2 +- core/include/core/rendering/renderPass.h | 18 +- .../rendering/{ => shaderc}/shaderLoader.h | 0 .../core/rendering/shaderc/slangMetadata.h | 35 ++ .../core/rendering/shaderc/slangRuntime.h | 44 ++ core/shaderc/CMakeLists.txt | 35 ++ .../rendering => shaderc}/shaderLoader.cpp | 8 +- core/shaderc/slangMetadata.cpp | 409 ++++++++++++++++++ core/shaderc/slangRuntime.cpp | 146 +++++++ core/src/rendering/contactShadowPass.cpp | 2 +- core/src/rendering/gbufferPass.cpp | 2 +- core/src/rendering/renderPass.cpp | 15 +- core/src/rendering/shaderCompiler.cpp | 13 +- core/src/rendering/shadowMapPass.cpp | 2 +- core/src/rendering/slangCompiler.cpp | 124 +----- core/src/rendering/ssaoPass.cpp | 2 +- core/src/rendering/toneMappingPass.cpp | 2 +- core/templates/shader_metadata.h.j2 | 62 --- core/tests/testContactShadowPass.cpp | 2 +- core/tests/testFrameGraph.cpp | 2 +- core/tests/testMeshCache.cpp | 2 +- core/tests/testPipelineBuilder.cpp | 29 +- core/tests/testRendererRegistry.cpp | 2 +- core/tests/testShaderLoader.cpp | 2 +- core/tests/testShadowMapPass.cpp | 2 +- core/tests/testSlangCompiler.cpp | 2 +- core/tests/testWebGpu.cpp | 16 +- editor/src/editorApplication.cpp | 4 +- editor/src/include/editorApplication.h | 2 +- editor/src/passes/editorPass.cpp | 2 +- editor/tests/testAutoExposure.cpp | 16 +- hello_triangle/src/main.cpp | 22 +- renderers/forward/forwardPass.cpp | 2 +- renderers/pathtracer/pathTracerPass.cpp | 2 +- tmp_plan/README.md | 25 -- tmp_plan/cpp-shader-compiler-tool.md | 75 ---- tmp_plan/linux-tool-builds.md | 79 ---- tools/CMakeLists.txt | 32 ++ tools/conan/slang/conanfile.py | 2 +- tools/conan/usdz_pack/conanfile.py | 36 -- tools/conan/usdz_pack/conanfile.txt | 10 + tools/conanfile.txt | 13 + tools/pts_shaderc/main.cpp | 194 +++++++++ tools/repo_tools/build/__init__.py | 11 + tools/repo_tools/build/command.py | 173 +++++++- tools/repo_tools/shader_codegen.py | 320 -------------- tools/repo_tools/slangc.py | 407 ++++------------- tools/repo_tools/tests/test_slangc.py | 115 ----- 58 files changed, 1403 insertions(+), 1317 deletions(-) rename core/include/core/rendering/{ => shaderc}/shaderLoader.h (100%) create mode 100644 core/include/core/rendering/shaderc/slangMetadata.h create mode 100644 core/include/core/rendering/shaderc/slangRuntime.h create mode 100644 core/shaderc/CMakeLists.txt rename core/{src/rendering => shaderc}/shaderLoader.cpp (85%) create mode 100644 core/shaderc/slangMetadata.cpp create mode 100644 core/shaderc/slangRuntime.cpp delete mode 100644 core/templates/shader_metadata.h.j2 delete mode 100644 tmp_plan/README.md delete mode 100644 tmp_plan/cpp-shader-compiler-tool.md delete mode 100644 tmp_plan/linux-tool-builds.md create mode 100644 tools/CMakeLists.txt delete mode 100644 tools/conan/usdz_pack/conanfile.py create mode 100644 tools/conan/usdz_pack/conanfile.txt create mode 100644 tools/conanfile.txt create mode 100644 tools/pts_shaderc/main.cpp delete mode 100644 tools/repo_tools/shader_codegen.py delete mode 100644 tools/repo_tools/tests/test_slangc.py diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 4b6d0ab..7df1d3d 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -44,9 +44,6 @@ jobs: runs-on: ${{ matrix.os }} strategy: fail-fast: false - # Windows must finish before Emscripten starts (USDZ scene dependency). - # max-parallel: 1 ensures sequential execution in platform order. - max-parallel: 1 matrix: platform: [windows-x64, emscripten] build_type: [Release] @@ -108,30 +105,19 @@ jobs: restore-keys: | ${{ matrix.platform }}-conan-${{ hashFiles('conanfile.py') }} - # Windows prebuild generates USDZ scenes;

The C++ OutputSlot DSL duplicated what the shader already declares — silent drift when a shader binding changed and C++ didn't match. - pts_shaderc metadata emitter dispatches on TypeReflection::Kind — ConstantBuffer/ParameterBlock, SamplerState, Resource (StructuredBuffer / Texture* / RWTexture*). Generates correct WGPUBindGroupLayoutEntry unions per binding, previously all emitted as buffer type. - Slang user attributes [DynamicBuffer], [NonFilterable], [NonFiltering] registered via IGlobalSession::addBuiltins. Metadata emitter reads them to set WGPU flags reflection can't infer (hasDynamicOffset, sampler Filtering vs NonFiltering, texture sampleType). - FrameGraph::bind_group_layout(name, WGPUBindGroupLayout) registers a caller-built layout and caches by name for dep-tracked versioning. Lookup-only bind_group_layout(name) fails loud if not pre-registered. - ~28 callsites across forward, pathtracer, editor, gbuffer, shadow, contact_shadow, ssao, tone-mapping migrated to ::create_bind_group_layout_N(device). Consumer BGLs registered by the consuming renderer (forward registers shadow_map/consumer from forward shader's reflection; ShadowMapPass / ContactShadowPass look up by name). - iblResources stays open-coded — its compute shaders patch RWTexture2D storage format at runtime (rgba32float → rgba16float) which reflection cannot predict. - testSlangMetadata.cpp covers uniform/[DynamicBuffer]/texture+sampler/ StructuredBuffer RO/RW/RWTexture2D cases. - Deletes: core/include/core/rendering/outputLayout.h + core/src/rendering/outputLayout.cpp, OutputSlot class, consumer_slots() / producer_slots() static helpers, slot-list overloads of FrameGraph::bind_group_layout. Native Debug + Release builds green; 51/51 tests pass including editorSmoke (brdf_test, kitchen_set, shadow_test, primitives, test_cube) and ptSmoke_glass_test.

add ASCII-only rule Replaces all non-ASCII characters in project source with ASCII equivalents: - Box drawing (U+2500) -> '-' - Em dash (U+2014) -> '--' - En dash (U+2013) -> '-' - Right arrow (U+2192) -> '->' - Check mark (U+2713) -> '[OK]' - Cross mark (U+2717) -> '[FAIL]' - Approx equal (U+2248) -> '~=' - Degree sign (U+00B0) -> 'deg' - Plus-minus (U+00B1) -> '+/-' - Multiplication sign (U+00D7) -> 'x' - Windows-1252 em dash (0x97 in ltcData.h) -> '--' Runtime-visible changes: build log output uses [OK]/[FAIL] instead of Unicode check/cross marks. The string matching in build/__init__.py was updated to match. Adds ASCII-only-source coding rule to CLAUDE.md Code Conventions.
