openGL中基于位图填充的图案掩模分析与设计

Pattern Mask Analysis and Design Based on Bitmap Filling in openGL

open GL中多边形的填充主要包括色彩填充、纹理插值图案填充和位图图案填充,主要对位图图案的填充方式进行讨论,掩模的设计是位图填充中的关键,重点讨论掩模的构成,并以实例介绍的掩模的设计方法,分析了图案填充的应用效果。

The polygon filling in openGL mainly includes color filling, texture interpolation pattern filling and bitmap pattern filling. This paper mainly discusses the filling mode of bitmap pattern, and the design of mask is the key in bitmap filling. The composition of mask is discussed emphatically, and the application effect of pattern filling is analyzed with the method of mask design introduced by an example.
