The WebGLRenderingContext.uniformMatrix[234]fv() methods of the WebGL API specify matrix values for uniform variables.
Syntax
void gl.uniformMatrix2fv(location, transpose, value); void gl.uniformMatrix3fv(location, transpose, value); void gl.uniformMatrix4fv(location, transpose, value);
Parameters
- location
- A
WebGLUniformLocationobject containing the location of the uniform attribute to modify. - transpose
- A
GLbooleanspecifying whether to transpose the matrix. Must befalse. value-
A
Float32Arrayor sequence of GLfloats.
Return value
None.
Examples
gl.uniformMatrix2fv(loc, false, [2,1, 2,2]);
