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.
