Baseline
Widely available
*
This feature is well established and works across many devices and browser versions. It’s been available across browsers since 2021年9月.
{"* "}Some parts of this feature may have varying levels of support.
WebGL 2 API 的 WebGL2RenderingContext.uniformMatrix[234]x[234]fv() 方法向 uniform 变量中传入指定的矩阵值。
备注：
这个方法不用 2x2、3x3 和 4x4 版本，它们通常分别用 2、3、4 简写表示，详见下方语法。
