Abstract:

Volume rendering is an important technique in data visualization, but it has some problems, such as low sampling efficiency and slow drawing speed. This is especially true for the model of body visualization calculation, where the scene rendering speed is too large and the throughput rate is too high. To improve the drawing speed of the volume rendering algorithm, a method of parallel GPU computing is proposed to optimize the algorithm. A parallel volume rendering algorithm based on GPU is implemented to improve the rendering speed, and the experimental results show that the algorithm can improve the speed without affecting the image quality.
