PKAssetTools

A repository of build tools used to cook assets for use in PKRenderer.

Features

• GLSL To spriv compilation.
• .obj to custom binary mesh format conversion.
• Lossless file compression (Huffman encoding).

Shader Format

• Converts glsl shader files to .pkshader files.
• Supports multiple compilation (in source glsl: #pragma pk_multi_compile VARIANT0 VARIANT1).
• The following attributes are parsed & stored from the source glsl:
  • Vertex attributes.
  • Descriptor sets.
  • Material property layout.
  • Rasterization parameters (blend mode, cull face, depth test mode, etc.).
  • multi compile keyword map.

Mesh Format

• Converts .obj files to binary files (.pkmesh) containing interleaved vertex data, index buffer & vertex buffer attributes.
• Optimizes output vertex & index buffers using zeux meshoptimizer.
• Generates meshlets and a directed acyclic graph lod structure.

Planned Features

• Add support for gltf conversion.
• Implement some form of asset packaging.

Dependencies

• C++ 17 support required
• mikktspace
• meshoptimizer
• tinyobjloader
• SPIRV-Reflect
• msdf-atlas-gen
• shaderc
• METIS
  • Due to the large sizes of the static libraries they were omitted from this repository. You can get them from the link above.
  • shaderc_combined.lib & shaderc_combinedd.lib specifically.
