This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The WebGL2RenderingContext.getUniformIndices() method of the WebGL 2 API retrieves the indices of a number of uniforms within a WebGLProgram.
Syntax
sequence<GLuint> gl.getUniformIndices(program, uniformNames);
Parameters
program- A
WebGLProgramcontaining uniforms whose indices to query. uniformNames- An
ArrayofDOMStringspecifying the names of the uniforms to query.
Return value
An Array of GLuint containing the uniform indices.
Examples
var uniformIndices = gl.getUniformIndices(program, ['UBORed', 'UBOGreen', 'UBOBlue']);
