ABSTRACT:
In an image processing method to form a predetermined image with an image processing unit having a frame-buffer and z-buffer corresponded to the frame-buffer, a main-model and a sub-model containing at least one part of the main model are arranged at a predetermined position in a virtual 3-dimensional space. The sub-model is rendered in the frame-buffer in a write-protected state to the z-buffer, after that, the main-model is rendered in the frame-buffer in a released write-protected state to the z-buffer and updating a memory content of the z-buffer according to depth information that the main model has.
