Effective Method for Arbitrary Clip Plane Extraction and Texture Mapping Based on Contour Data of Images
Zhuang Chen · 2009
Targeted to arbitrary cutting of surface model by 3D reconstruction,this paper first removed the object’s background by its contour data,and then computed the intersecting polygon of cutting plane and bounding box of the model in model and image spaces.Then fast extracted the texture of section planes with vector superposition principle and cubic linear interpolation.Last the section texture passing alpha test was mapped to the clip section in the model space.Experiments’ testing shows the method solves the problem that inner data is invisible by surface rendering,effectively improving the texture rendering speed of arbitrary clip.
