Projector

Projector is a WIP highly experimental asynchronous reprojection demo application built on Vulkan.

Usage

The application features user-controllable first-person camera view in a basic 3D scene. Also included is a user interface that can be used to control various reprojection and rendering parameters.

Controls

Key	Use
Mouse move	Look around
WASD	Move camera/character
ALT	Release mouse cursor (use UI)
ALT + ENTER	Toggle fullscreen
ESC	Quit application

Prerequisites

Hardware

A graphics card with Vulkan 1.3 and variable rate shading support. A non-exhaustive and largely untested list of suitable cards:

• Nvidia: Turing architecture or newer
  • GeForce 20/16 series or newer
  • Quadro RTX 3000 or newer
• AMD: RDNA 2 architecture or newer
  • Radeon RX 6000 or newer
  • Radeon Pro W6000 or newer
• Intel: Xe (Gen12) architecture or newer
  • Arc 300/700 series or newer
  • UHD Graphics 700 series or newer
  • Iris Xe Graphics G7 or newer

Tools

• CMake: https://cmake.org/download
• (Highly recommended) vcpkg: https://github.com/microsoft/vcpkg

SDKs

• Vulkan SDK: https://vulkan.lunarg.com

Libraries

• Vulkan libktx: https://github.com/KhronosGroup/KTX-Software
• glwf3: https://www.glfw.org/download
• glm: https://github.com/g-truc/glm
• Dear ImGui: https://github.com/ocornut/imgui

If using vcpkg, the libraries can be installed with

vcpkg install

Generating build targets

cmake -B build

If using vcpkg, you may need to additionally provide the vcpkg toolchain file via the DCMAKE_TOOLCHAIN_FILE flag, e.g.

cmake -B build -DCMAKE_TOOLCHAIN_FILE=<path_to_vcpkg>/scripts/buildsystems/vcpkg.cmake

Building

cmake --build build
