这是 实验性技术
检查 浏览器兼容性表格 要小心谨慎在生产中使用这之前。

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

没有 2x2 , 3x3 ，和 4x4 versions of this method. They are abbreviated in 2 , 3 ，和 4 , respectively. See the syntax below.

句法 

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);

参数

location
A WebGLUniformLocation object containing the location of the uniform attribute to modify.
transpose
A GLboolean specifying whether to transpose the matrix. Must be false .
data
A Float32Array of float values.

返回值

None.

范例 

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