dgl-shadertool

Set of tools / a pipeline for shader code transpilation: GLSL -> (SPIRV) -> GLSL/HLSL/MLSL

Build

Works only on macOS.

brew install glslang

./build.sh

Usage

./bin/glslcompile.sh ./test/shaders-src/test01.glsl ./test/shaders glsl100

Example shader

@vs MyShaderVS
layout(std140) uniform params
{
  mat4 uMVP;
};

in vec4 position;
in vec3 normal;
out vec3 vNormal;

void main()
{
  gl_Position = uMVP * position;
  vNormal = normal;
}
@end

@fs MyShaderFS
precision mediump float;
in vec4 color;
out vec4 fragColor;
void main() {
  fragColor = color;
}
@end

@program glsl300es MyShader MyShaderVS MyShaderFS

@vf @fs are followed by the name of a block, but the name is optional.

@program tag is optional, as well as its parameters can be skipped.

Credits

dgl-spirv-cross is based on the code from oryol-shdc by Andre Weissflog ( @floooh )

Shader .glsl file structure is taken from oryol-shdc, but parser is my own, so it may behave differently.

Main tools used in the pipeline:

• glslang
• Khronos SPIRV-Cross
