VSB Migration Scripts

This directory contains C# scripts for UVTools, migrating functionality from Voxel-Stack-Blender (VSB) and adding new features.

Script: Enhanced EDT Blending (ScriptEnhancedEDT.cs & ScriptEnhancedEDTParallel.cs)

Purpose: Anti-aliasing along the Z-axis using an Enhanced Euclidean Distance Transform. Smooths transitions between layers.

UI Options:

• Fade Distance: Max distance (pixels) for blending.
• Receding Layers: Number of previous layers to consider.
• Factor Anisotropy: Account for non-square pixels.
• X/Y Pixel Size (µm): Pixel dimensions.
• Thread Count: (Parallel) Number of threads.

Threading: Parallel version uses Parallel.For.

Script: Exposure Calibration Masking (ExposureCalibrationMasking.cs)

Purpose: Creates a calibration file by splitting each layer into multiple sub-exposures with incremental masking. This allows testing multiple exposure times on a single print by partitioning the build plate.

UI Options:

• Divisions X/Y: Number of partitions along X and Y axes. Total partitions = X * Y.
• Align Left/Top: Controls the ordering of the incremental exposure.

Logic: Each original layer is replicated TotalDivisions times (at the same Z height). For each subsequent sub-layer, one additional partition is masked out (black). This results in the first partition receiving 1 exposure unit, the second 2 units, and so on. Lift movements are disabled between sub-layers.

Script: LUT Engine (ScriptLUTEngine.cs)

Purpose: Applies a 1D Look-Up Table (LUT) to layer brightness.

UI Options:

• LUT File: Path to .lut file (JSON array of 256 ints).

Threading: Uses Parallel.For.

Script: SDF Generation (ScriptSDF.cs)

Purpose: Generates a 2D Signed Distance Field from the layer image.

UI Options:

• Spread: Max distance.
• Inside: Generate inside/outside.

Threading: Uses Parallel.For.

Script: SDF Generation (Enhanced) (ScriptSDF-Enhanced.cs)

Purpose: Advanced SDF with anisotropic scaling and grayscale mapping.

UI Options:

• Factor Anisotropy: Enable scaling.
• X/Y Pixel Size: Dimensions in µm.
• Thresholds: Lower/Upper distance limits for mapping.
• Gamma: Correction curve.

Threading: Uses Parallel.For with unsafe code for performance.

Script: NanoDLP Multi-Exposure Import (NanoDLPMultiExposureImport.cs)

Purpose: Imports NanoDLP slice files (Zip or Folder) with multi-exposure per layer. Handles custom JSON arrays and file naming.

UI Options:

• NanoDLP File/Folder: Source.
• Packed RGB (3:1): Unpack RGB images to high-res grayscale.

Threading: Batched Multi-threading. reads files sequentially in batches, then processes (decodes/unpacks) them in parallel to balance IO and CPU usage while managing RAM.

Script: NanoDLP Multi-Exposure Export (NanoDLPMultiExposureExport.cs)

Purpose: Exports to NanoDLP multi-exposure format (.nanodlp zip).

UI Options:

• Output File: Destination zip.
• Divisor: Sub-layers per layer.
• Exposure Times: Comma-separated list.
• Pack into RGB: Pack grayscale to 3:1 RGB.

Threading: Batched Multi-threading. Processes layers (encodes/packs) in parallel batches, then writes to Zip sequentially.
