WEBGL_debug_shaders.getTranslatedShaderSource()
The WEBGL_debug_shaders.getTranslatedShaderSource()
method is part of the WebGL API and allows
you to debug a translated shader.
Syntax
getTranslatedShaderSource(shader)
Parameters
shader-
A
WebGLShaderto get the translated source from.
Return value
A String containing the translated shader source. An empty string is
returned, if:
- no source has been defined or,
WebGLRenderingContext.compileShader()has not yet been called or,- the translation for the shader failed.
Examples
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));
// }"
