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

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

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.
