Abstract

In this paper, we introduce a new deformable volume rendering algorithm. By embedding deformation into the visualization loop, we render the deformedvolume directly without going through the expensive and noninteractive volume reconstruction process. The volume deformation is done using a radial basis function that is piecewise linearly approximated by an adaptive space subdivision of the octree encoded target volume. The octree blocks in the target volume are reverse morphed and projected in a front-to-back order. A template based ray-block intersection method is used to speed up the rendering process. Our algorithm renders the morphing of a 256(3) volume in seconds. While the resultant timings is slower than real time, it is much fasterthan existing volume morphing/rendering pipelines, (C) 2000 Elsevier Science B.V. All rights reserved.
