"WebThe perspective projection describes perspective viewing of the scene. Points in the scene are projected onto a viewing plane perpendicular to the z axis. The Perspective () function computes this transformation; it takes a field-of-view angle in fov and the distances to a near z plane and a far z plane. " - Perspective projection matrix fov
