Image Based Interactive Visualization and Data Compression
基于图象的交互绘制和数据压缩

The speed of volume rendering is the bottleneck of interactive visualization. In the paper, an original fast rendering system using image based rendering is presented, which greatly improves the speed of interactive visualization by combining the image based rendering and previous volume rendering. At first, a list of sample images is generated by ray tracing. Next these images are compressed by warping transformation. At last, random new view images can be rendered in speed of faster than 50 frames per second. In order to improve the speed more, a fast warping formula is developed
