| 摘 要： | 传统的光线投射算法能够得到清晰的体绘制图像,但由于其运行量巨大,导致速度慢,性能低。J.Krüger等人提出了基于GPU的光线投射算法大幅度地提高了绘制性能,但在图像融合阶段仍未能充分利用GPU的向量运算的优势。为此,本文将图像融合阶段部分标量运算转换为向量和矩阵运算,绘制性能得到了进一步提升。

| Abstract: | Traditional RaY-casting algerithm can get clear image,but the performance is low because of the huge computing. J.Krue get and other igeople posed a new algorithm based on GPU which make a big step on performance.But in the stage＇of image composition,the advantages of the vector computing on GPU can not be used very well.So,this thesis transfer the scalar computing into vector computing on image composition stage,which make further progress. |
