Parameters

location

A WebGLUniformLocation object containing the location of the uniform attribute to modify.

value, v0, v1, v2, v3

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

• A floating point Number for floating point values (methods with "f").
• A Float32Array for floating point vector methods (methods with "fv").
• An integer Number for integer values (methods with "i").
• An int32Array for integer vector methods (methods with "iv").

Return value

None.

Examples

gl.uniform1f(u_alpha, 0.8);
