WebGL2RenderingContext: uniformMatrix[234]x[234]fv() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2021.

Note: This feature is available in Web Workers.

The WebGL2RenderingContext.uniformMatrix[234]x[234]fv() methods of the WebGL 2 API specify matrix values for uniform variables.

Note: There are no 2x2, 3x3, and 4x4 versions of this method. They are abbreviated in 2, 3, and 4, respectively. See the syntax below.

Parameters

location

A WebGLUniformLocation object containing the location of the uniform attribute to modify.

transpose

A GLboolean specifying whether to transpose the matrix.

data

A Float32Array of float values.

Return value

None (undefined).

Examples

js
gl.uniformMatrix2x3fv(loc, false, [1, 2, 3, 4, 5, 6]);
