WEBGL_debug_shaders: getTranslatedShaderSource() method
The WEBGL_debug_shaders.getTranslatedShaderSource()
method is part of the WebGL API and allows
you to debug a translated shader.
Syntax
js
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:
- no source has been defined or,
WebGLRenderingContext.compileShader()
has not yet been called or,- the translation for the shader failed.
Examples
js
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));
// }"
