An Interactive Exploded View Generation using Block-based Re-rendering

Exploded view generation for volumetric object is a useful method in surgical simulation, but it is very hard to perform real-time operation. We present an interactive method to determine interesting regions and to render a scene with varying volume datasets in real-time. In general, since conventional methods are designed to solve the problem of occlusion of sub-volumes, they did not consider performance. Especially, exploded view generation methods are difficult to render a scene in real-time even in the case of exploiting highly optimized method. Because they perform volume rendering after defining rules to split an original volume and constraints to order sub-volumes. We present an interactive cutting operation using GPU-based parallel processing and real-time rendering using block-based re-rendering method.
