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

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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

ui stands for unsigned integer, i for integer, f for float, and v for vector.
Not all combination are valid: ui can be combined with v, but not i or f. See the syntax table below.

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.
value, 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.
