Abstract:
1. A three-dimensional (3D) graphics clipping method, for clipping a visible portion of at least one stereoscopic object in a 3D space, the 3D graphics clipping method comprising: obtaining a plurality of vertexes of a triangle by a 3D graphics processing apparatus, wherein the stereoscopic object is constructed by using a plane of the triangle; determining whether a view point is located between a first near clipping plane and a far clipping plane to generate a determination result by the 3D graphics processing apparatus; setting a second near clipping plane according to the determination result and setting a view field between the second near clipping plane and the far clipping plane by the 3D graphics processing apparatus; and executing a near clipping procedure on the triangle according to the second near clipping plane by the 3D graphics processing apparatus, wherein the step of setting the second near clipping plane according to the determination result and setting the view field between the second near clipping plane and the far clipping plane by the 3D graphics processing apparatus comprises:
