Simulating Free-form Volume Deformation by Inverse-deformed Ray
利用反向光线弯曲实现体数据模型的自由变形模拟*

A ray-deformation-based volume rendering technique for the simulation of free-form volume deformation was presented.In addition,the traditional optimization strategies for accelerating volume rendering were adopted in the deformation scheme,helping reduce the calculations which contribute nothing to the final rendering results.The experimental results show that the developed techniques can considerably accelerate the volume rendering and deformation procedure.
