In this paper, by projecting onto right image plane the intermediate images composited from the images on successive slicing planes, while rendering the left image based on a series of parallel slicing planes [Yage96] , the computation of composition in rendering the right image can be reduced, and the efficiency of stereoscopic rendering can be improved.

为此，本文在采用基于一组平行切割平面的体绘制方法生成左视图的过程中[Yage96]，通过将连续若干层切割平面上的中间采样图像先进行合成，将合成后的结果再投影到右图像平面上，从而减少右视图生成过程中对图像合成的计算量，提高立体绘制效率。
