The WebGLRenderingContext.uniformMatrix[234]fv()
methods of the WebGL API specify matrix values for uniform variables.
The three versions of this method (uniformMatrix2fv()
, uniformMatrix3fv()
, and unifomMatrix4fv()
) take as the input value 2-component, 3-component, and 4-component vectors, respectively.
Syntax
WebGLRenderingContext.uniformMatrix2fv(location, transpose, value); WebGLRenderingContext.uniformMatrix3fv(location, transpose, value); WebGLRenderingContext.uniformMatrix4fv(location, transpose, value);
Parameters
location
- A
WebGLUniformLocation
object containing the location of the uniform attribute to modify. The location is obtained usinggetUniformLocation()
. transpose
- A
GLboolean
specifying whether to transpose the matrix. Must befalse
. value
-
A
Float32Array
or sequence ofGLfloat
values.
Return value
undefined
Examples
gl.uniformMatrix2fv(loc, false, [2,1, 2,2]);
