Focused on the display of the texture on the arbitrary clip plane of 3D reconstructed surface model,this paper presented a two-phase approach to solve the issue,namely,the 3D texture sampling phase and the section texture mapping phase.In the first phase,determined the 3D texture's position and removed its background by the bounding box and the transect outline of the cutting model,then weaved the multi-precision 3D texture by sampling.In the second phase,computed the intersecting polygons of cutting plane and the bounding boxes in the model and texture spaces,and the fast abstracted image of the texture space on it using vector superposition principle and cubic linear interpolation.Then mapped the section texture to the clip section in the model space after Alpha testing,thus formed the cutting model with section texture.Experiments show that the proposed method solves the problem that inner data is invisible in surface rendering,and effectively improves the texture rendering speed of arbitrary clip plane.
