The WEBGL_debug_shaders.getTranslatedShaderSource() method is part of the WebGL API and allows you to debug a translated shader.
getTranslatedShaderSource(shader)shaderA WebGLShader to get the translated source from.
A String containing the translated shader source. An empty string is returned, if:
WebGLRenderingContext.compileShader() has not yet been called or,const canvas = document.getElementById("canvas");
const gl = canvas.getContext("webgl");
const shader = gl.createShader(gl.FRAGMENT_SHADER);
gl.shaderSource(
shader,
"void main() { gl_FragColor = vec4(gl_FragCoord.x, 0.0, 0.0, 1.0); }",
);
gl.compileShader(shader);
const src = gl
.getExtension("WEBGL_debug_shaders")
.getTranslatedShaderSource(shader);
console.log(src);
// "void main(){
// (gl_FragColor = vec4(gl_FragCoord.x, 0.0, 0.0, 1.0));
// }"
