Disclosed is an interactive non-uniform translucent object rendering method. The method supports the operations such as object model carving, material editing and the like, and all operations can be interactively conducted. The present invention mainly has two technical breakthroughs and innovations: firstly, proposing a novel diffusion equation solving method, overcoming the defect that the former methods cannot generate a rendering result via interaction when the topology structure of the object changes; and secondly, adopting a parallel multi-grid acceleration technology, enabling a rendering process to achieve the interactive or even real time level. The whole solving process is highly parallelized and extraordinarily easy to realize on a GPU, and the rendering result thereof is almost identical with the rendering result of a finite element method consuming more time. |
