句法

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

参数

shader: WebGLShader to get the translated source from.

返回值

A 字符串 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.

范例

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));
// }"
