三维立体显示中的纹理误差消除

在两步纹理映射算法中,一般以半球面作为中介面来进行立体投影,由于球体的不可延展性,在映射的过程中不可避免的会产生较大的纹理形变,严重影响了立体显示的真实感.分析了传统的基于立体投影映射的方法产生纹理形变的原因,将纹理不变形准则与半球面纹理映射技术相结合,并采用了双中心立体投影算法进行三维立体显示,提高了立体显示中纹理映射的质量,有效的消除了立体显示中的纹理误差,具有较好的真实感.

Elimination of texture distortion in three-dimensional display

In the two-part texture mapping algorithms,hemisphere is used as an intermediary surface,because of the untractility of the ball,the texture distortion is unavoidable,and a serious impact on the stereoscopic display realistic.By analyzing the traditional method,we find the reason why the texture distortion will be produced.After combining the principle of invariability of ratio of areas with the hemisphere texture mapping technique,and using the double-center three-dimensional display algorithms,the quality...
