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

    Syntax

    void gl.uniform1ui(location, v0);
void gl.uniform1uiv(location, value);

void gl.uniform2ui(location, v0, v1);
void gl.uniform2uiv(location, value);

void gl.uniform3ui(location, v0, v1, v2);
void gl.uniform3uiv(location, value);

void gl.uniform4ui(location, v0, v1, v2, v3);
void gl.uniform4uiv(location, value);

    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").
    • A Uint32Array for unsigned integer vector methods (methods with "uiv").

    Return value
