Parameters

shader

A WebGLShader to get the translated source from.

Return value

A String containing the translated shader source. An empty string is returned, if:

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));
// }"
