球的描绘与遮挡。

简介：
The rendering of MFC balls and their occlusion techniques are presented here. This document details the processes involved in generating visual representations of these spherical objects, alongside the methods used to manage their visibility within a scene – specifically addressing how they become obscured or hidden from view. A thorough examination of the drawing procedures for MFC balls is provided, encompassing the specific steps taken to create accurate and realistic depictions. Furthermore, the mechanisms for controlling their occlusion are explored, outlining strategies and algorithms employed to ensure proper visual behavior when these balls interact with other elements in a 3D environment.
