OpenGL 图ii形消隐质量的改善

摘要

分析了用一般方法在OpenGL中进行图形消隐时存在消隐质量问题的产生原因，提出了两种具体的改善消隐质量方法，即模板缓冲区校验法和多边形偏移量修正法。在方法说明之后，给出了具体开发过程实例，并对它们进行了比较，指出了其分别适用的条件。%This paper analyzes the quality problem of hidden - image using common method to draw images in OpenGL, putsforward two methods to improve on that: stencil buffer verification and polygon offset modification. The author explains them in detail,and gives two examples using the two methods. After that, the author compares them, and illuminates the conditions in which they canbe used.
