The WebGLRenderingContext.uniformMatrix[234]fv() methods of the WebGL API specify matrix values for uniform variables.

The three versions of this method (uniformMatrix2fv(), uniformMatrix3fv(), and unifomMatrix4fv()) take as the input value 2-component, 3-component, and 4-component vectors, respectively.


WebGLRenderingContext.uniformMatrix2fv(location, transpose, value);
WebGLRenderingContext.uniformMatrix3fv(location, transpose, value);
WebGLRenderingContext.uniformMatrix4fv(location, transpose, value); 


A WebGLUniformLocation object containing the location of the uniform attribute to modify. The location is obtained using getUniformLocation().
A GLboolean specifying whether to transpose the matrix. Must be false.

A Float32Array or sequence of GLfloat values.

Return value



gl.uniformMatrix2fv(loc, false, [2,1, 2,2]);
