Check the Browser compatibility table carefully before using this in production.
The WebGL2RenderingContext.uniformMatrix[234]x[234]fv() methods of the WebGL 2 API specify matrix values for uniform variables.
There are no 2x2, 3x3, and 4x4 versions of this method. They are abbreviated in 2, 3, and 4, respectively. See the syntax below.
Syntax
void gl.uniformMatrix2fv(location, transpose, data, optional srcOffset, optional srcLength); void gl.uniformMatrix3x2fv(location, transpose, data, optional srcOffset, optional srcLength); void gl.uniformMatrix4x2fv(location, transpose, data, optional srcOffset, optional srcLength); void gl.uniformMatrix2x3fv(location, transpose, data, optional srcOffset, optional srcLength); void gl.uniformMatrix3fv(location, transpose, data, optional srcOffset, optional srcLength); void gl.uniformMatrix4x3fv(location, transpose, data, optional srcOffset, optional srcLength); void gl.uniformMatrix2x4fv(location, transpose, data, optional srcOffset, optional srcLength); void gl.uniformMatrix3x4fv(location, transpose, data, optional srcOffset, optional srcLength); void gl.uniformMatrix4fv(location, transpose, data, optional srcOffset, optional srcLength);
Parameters
- location
- A
WebGLUniformLocationobject containing the location of the uniform attribute to modify. - transpose
- A
GLbooleanspecifying whether to transpose the matrix. Must befalse. - data
- A
Float32Arrayof float values.
Return value
None.
Examples
gl.uniformMatrix2x3fv(loc, false, [1, 2, 3, 4, 5, 6]);
