ShaderConductor

ShaderConductor is a tool designed for cross-compiling HLSL to other shading languages.

Features

• Converts HLSL to readable, usable and efficient GLSL
• Converts HLSL to readable, usable and efficient ESSL
• Converts HLSL to readable, usable and efficient Metal Shading Language (MSL)
• Converts HLSL to readable, usable and efficient old shader model HLSL
• Supports all stages of shaders, vertex, pixel, hull, domain, geometry, and compute.

Note that this project is still in an early stage, and it is under active development.

Architecture

ShaderConductor is not a real compiler. Instead, it glues existing open source components to do the cross-compiling.

1. DirectX Shader Compiler to compile HLSL to DXIL or SPIR-V,
2. SPIRV-Cross to convert SPIR-V to target shading languages.

Prerequisites

• Git.
• Visual Studio 2017. Select the following workloads: Universal Windows Platform Development and Desktop Development with C++.
• CMake. Version 3.9 or up. It's highly recommended to choose "Add CMake to the system PATH for all users" during installation.
• Python. Version 2.7 or up. You need not change your PATH variable during installation.
• (Optional) Windows Driver Kit. DirectXShaderCompiler's tests are built using the TAEF framework. Unless you have the Windows Driver Kit installed, you should run the script at External\DirectXShaderCompiler\utils\hct\hctgettaef.py from your build environment before you start building to download and unzip it as an external dependency. You should only need to do this once.

Building

ShaderConductor has been tested on Windows. Linux and macOS support are coming soon.

The script way:

  BuildAll.py <BuildSystem> <Architecture> <Configuration>

where,

• <BuildSystem> can be ninja or vs2017. Default is vs2017.
• <Architecture> can be x64 or x86. Default is x64.
• <Configuration> can be Debug, Release, RelWithDebInfo, or MinSizeRel. Default is Release.

This script automatically grabs external dependencies to External folder, generates project file in Build/--, and builds it.

The manual way:

  mkdir Build
  cd Build
  cmake -G "Visual Studio 15" -T v141,host=x64 -A x64 ../
  cmake --build .

After building, the output file ShaderConductor.dll can be located in <YourCMakeTargetFolder>/Bin/<Configuration>/. It depends on dxcompiler.dll in the same folder.
