Abstract:
This paper presents a new medical data visualiz ation method called multi-resolution blending rendering which has been deve lope d for visualizing the large medical volume data sets. Different from those multi -resolution rendering methods which simplify the structures by polygon mesh opt imization technique, the new method uses different resolution levels to represen t different parts of a structure at the same time. So, it can preserve the integ rality of the structure and emphasize the important part of the structure when simplifying the structure. The new method also takes advantage of the good qualit ies of the wavelet transform and constructs the multi-resolution blending model of the structureby orthogonal wavelet transform and transition operator. The experiment proves that our method can effectively simplify the model of the structure, enormously reduce the number of the triangle of the structure and speedup the structure rendering. It is especially suitable for interactive observations on a complex medical structure.
