Abstract:

Simulation results are presented with vertices and polygons which did not adequately support display of complex scenes of point-cloud data when using traditional methods. Thus we use a hierarchical point-based representation algorithm for rendering, and introduce a mesh-interpolation algorithm to fill the gaps in the advance of the surface. Meanwhile, a model for lithography development based on the Dill algorithm, the Kim model and the ray algorithm is established. Experimental results show that the hierarchical point-based rendering algorithm is effective for the real-time realization of large-scale 3D visualization.

Key words: point based rendering, lithography development, level of detail hierarchy
