The WEBGL_debug_shaders.getTranslatedShaderSource() method is part of the WebGL API and allows you to debug a translated shader.

Syntax

gl.getExtension('WEBGL_debug_shaders').getTranslatedShaderSource(shader);

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:

Examples

var canvas = document.getElementById('canvas');
var gl = canvas.getContext('webgl');

var 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);

var 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));
// }"
