Abstract
A three-dimensional (3D) graphics clipping method, a 3D graphics displaying method, and a 3D graphics processing apparatus using the same are provided. The 3D graphics clipping method includes following steps. A plurality of vertexes of a triangle is obtained, wherein a 3D object is constructed by using a plane of the triangle. Whether a view point is located between a first near clipping plane and a far clipping plane is determined. A second near clipping plane is set according to the determination result, and a view field is set between the second near clipping plane and the far clipping plane. A near clipping procedure is executed on the triangle according to the second near clipping plane. In the 3D graphics clipping method, a correct view field is determined in advance so that a graphics processing procedure is efficiently sped up and the accuracy of the near clipping procedure is increased.
