Stencil buffer 模版缓冲

In this program the stencil buffer is filled with 1s wherever a white stripe is drawn and 0s elsewhere. Two versions of each oval, square, or triangle are then drawn. A black colored shape is drawn where the stencil buffer is 1, and a white shape is drawn where the buffer is 0.

A stencil buffer is an extra buffer, in addition to the color buffer and depth buffer (z-buffering) found on modern graphics hardware. The buffer is per pixel, and works on integer values, usually with a depth of one byte per pixel. The depth buffer and stencil buffer often share the same area in the RAM of the graphics hardware.
