针对交互式动态体绘制算法生成图像质量差的问题,提出一种改进算法,在减少使用插值的同时,通过增加采样点数和使用采样点间距离作为权值等方法进行图像合成。改进的算法使结果图像的质量有了明显改善,同时保持了较快的速度。
A modified volume rendering algorithm is proposed to overcome problems existing in the interactive dynamic volume rendering algorithm, such as the blurred resulting image. By decreasing use of interpolation, increasing the number of sampling points and adopting the interval of sampling points as weight, the modified algorithm can improve the quality of the resulting image and can maintain the speed of the rendering process.
