Syntax
JavaScript
Copy Code
gl.getExtension('WEBGL_debug_shaders').getTranslatedShaderSource(shader);

has not yet been called or,- the translation for the shader failed.
Examples
JavaScript
Copy Code
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)); // }"
