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.

* Some parts of this feature may have varying levels of support.

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.
