Abstract :
Splatting is an important object-order direct volume rendering algorithm which projects each voxel onto the view plane and composite it into a accumulating image by using a preintegrated interpolation kernels called footprint. Popular sheet-buffer based splatting algorithms overcome most problems at the cost of leading to popping artifacts. In this paper we present a new splatting volume rendering method which integrates a new defined view-buffer which is most parallel to the image plane, a new voxel traversal ordering along created view-buffer and a new footprint function construction method which makes each voxel contribute to more than one view-buffer by using a preintegrated three dimensional lookup table. The proposed method can not only efficiently eliminate splatting artifacts expecially popping artifacts but also obtain higher quality and refined rendering images than the conventional Splatting at a optimized speed.
