WebGL2RenderingContext.uniform[1234][uif][v]()

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?

Syntax

void gl.uniform1ui(location, v0);
void gl.uniform2ui(location, v0, v1);
void gl.uniform3ui(location, v0, v1, v2);
void gl.uniform4ui(location, v0, v1, v2, v3);
void gl.uniform1fv(location, data, optional srcOffset, optional srcLength);
void gl.uniform2fv(location, data, optional srcOffset, optional srcLength);
void gl.uniform3fv(location, data, optional srcOffset, optional srcLength);
void gl.uniform4fv(location, data, optional srcOffset, optional srcLength);
void gl.uniform1iv(location, data, optional srcOffset, optional srcLength);
void gl.uniform2iv(location, data, optional srcOffset, optional srcLength);
void gl.uniform3iv(location, data, optional srcOffset, optional srcLength);
void gl.uniform4iv(location, data, optional srcOffset, optional srcLength);
void gl.uniform1uiv(location, data, optional srcOffset, optional srcLength);
void gl.uniform2uiv(location, data, optional srcOffset, optional srcLength);
void gl.uniform3uiv(location, data, optional srcOffset, optional srcLength);
void gl.uniform4uiv(location, data, optional srcOffset, optional srcLength);

Parameters

location

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

Return value

None.
