WebGL2RenderingContext：uniform[1234][uif][v]() 方法

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⁩.

备注： 此特性在 Web Worker 中可用。

WebGL API 的 WebGL2RenderingContext.uniform[1234][uif][v]() 方法指定了 uniform 变量的值。

备注： ui 指无符号整数，i 指整数，f 指浮点数，而 v 则指向量。并不是所有的组合都是有效的：u 不能与 f 组合。详见下方语法表格。等价的正则表达式：uniform[1234](u?i|f)v?
