Note: This feature is available in Web Workers.

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

uniformMatrix2fv(location, transpose, value)
uniformMatrix3fv(location, transpose, value)
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

None (undefined).
