MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

WebGL2RenderingContext.getUniformIndices()

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 WebGLProgram containing uniforms whose indices to query.
uniformNames
An Array of DOMString specifying 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']);
