Web/API/WebGLRenderingContext/uniformMatrix

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 uniformMatrix4fv()) take as the input value 2-component, 3-component, and 4-component square matrices, respectively. They are expected to have 4, 9 or 16 floats.

Syntax

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

Parameters

location: A WebGLUniformLocation object containing the location of the uniform attribute to modify. The location is obtained using getUniformLocation().
transpose: A GLboolean specifying whether to transpose the matrix. Must be false.
value: A Float32Array or sequence of GLfloat values. The values are assumed to be supplied in column major order.

Return value

undefined

Examples

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