The WebGL2RenderingContext.uniformMatrix[234]x[234]fv() methods of the WebGL 2 API specify matrix values for uniform variables.

Note: There are no 2x2, 3x3, and 4x4 versions of this method. They are abbreviated in 2, 3, and 4, respectively. See the syntax below.


uniformMatrix2fv(location, transpose, data)
uniformMatrix2fv(location, transpose, data, srcOffset)
uniformMatrix2fv(location, transpose, data, srcOffset, srcLength)

uniformMatrix3x2fv(location, transpose, data)
uniformMatrix3x2fv(location, transpose, data, srcOffset)
uniformMatrix3x2fv(location, transpose, data, srcOffset, srcLength)

uniformMatrix4x2fv(location, transpose, data)
uniformMatrix4x2fv(location, transpose, data, srcOffset)
uniformMatrix4x2fv(location, transpose, data, srcOffset, srcLength)

uniformMatrix2x3fv(location, transpose, data)
uniformMatrix2x3fv(location, transpose, data, srcOffset)
uniformMatrix2x3fv(location, transpose, data, srcOffset, srcLength)

uniformMatrix3fv(location, transpose, data)
uniformMatrix3fv(location, transpose, data, srcOffset)
uniformMatrix3fv(location, transpose, data, srcOffset, srcLength)

uniformMatrix4x3fv(location, transpose, data)
uniformMatrix4x3fv(location, transpose, data, srcOffset)
uniformMatrix4x3fv(location, transpose, data, srcOffset, srcLength)

uniformMatrix2x4fv(location, transpose, data)
uniformMatrix2x4fv(location, transpose, data, srcOffset)
uniformMatrix2x4fv(location, transpose, data, srcOffset, srcLength)

uniformMatrix3x4fv(location, transpose, data)
uniformMatrix3x4fv(location, transpose, data, srcOffset)
uniformMatrix3x4fv(location, transpose, data, srcOffset, srcLength)

uniformMatrix4fv(location, transpose, data)
uniformMatrix4fv(location, transpose, data, srcOffset)
uniformMatrix4fv(location, transpose, data, srcOffset, srcLength)



A WebGLUniformLocation object containing the location of the uniform attribute to modify.


A GLboolean specifying whether to transpose the matrix. Must be false.


A Float32Array of float values.

Return value

None (undefined).


gl.uniformMatrix2x3fv(loc, false, [1, 2, 3, 4, 5, 6]);
