block_compression

Crate API

Texture block compression using WGPU compute shader. The shaders are a port of Intel's ISPC Texture Compressor's kernel to WGSL compute shader.

Tested with the following backends:

  • DX12
  • Metal
  • Vulkan

Supported block compressions

Currently supported block compressions are:

  • BC1
  • BC2
  • BC3
  • BC4
  • BC5
  • BC6H
  • BC7

DX12 pipeline creation

The pipeline creation for BC7 and especially BC6H takes a long time under DX12. The DXC compiler seems to take a very long time to compile the shader. For this reason we moved them behind features, which are included in the default features.
