Convert GLSL to HLSL with 100% precision!

Have you tried translating GLSL code to HLSL and for some reason it never works, even through you've gone through it line by line? For example with noise functions.

Then do this!

• Save your shader to a file and add to the top:

  #version 460
  precision mediump float;

  and make sure to add a main() function, calling your function such as:

  void main() {
    // code here so it doesn't get optimized away
  }
  

• Download glslcc and run

  glslcc.exe --frag=shader.glsl --output=shader --lang=hlsl

• Now you have cursed hlsl but working code! float param_1 = youreWelcome.z.xxxx

D:\glsl-shaders\crt\shaders>I:\glslcc-1.7.6-win64\glslcc.exe --frag=crtgeom.glsl --output=CRTshader --lang=hlsl
Link failed:
ERROR: Linking fragment stage: Missing entry point: Each stage requires one entry point

@0wwafa did you add void main() {} with code calling to the functions you need translated? glslcc will optimize unused code away.
