- Model I/O
Model I/O automatically derives this property from the
field properties. A renderer uses this matrix, along with view and model matrices derived from the camera’s position and orientation (its inherited
transform property) and the content to be rendered, to transform vertex data to the renderer’s 2D screen space at render time.
