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

{{APIRef("WebGL")}} {{AvailableInWorkers}} 

The WebGL2RenderingContext.uniform[1234][uif][v]() methods of the WebGL API specify values of uniform variables.

Note: ui stands for unsigned integer, i for integer, f for float, and v for vector. Not all combinations are valid: u cannot be combined with f. See the syntax table below. Equivalent Regex: uniform[1234](u?i|f)v?

Parameters

• location

  • : A {{domxref("WebGLUniformLocation")}}  object containing the location of the uniform attribute to modify.

• data, v0, v1, v2, v3

  • : A new value to be used for the uniform variable. Possible types:

    • A {{jsxref("Number")}}  for unsigned integer values (methods with ui), for integer values (methods with i), or for floats (methods with f).
    • A {{jsxref("Uint32Array")}}  for unsigned integer vector methods (methods with uiv).

Return value

None ({{jsxref("undefined")}} ).
