Sampling Method on 3D Model Surface Based on Quasi Random Sequence
Fuyun Liu · Jisuanji gongcheng · 2008
Shape distribution algorithm of 3D model retrieve uses pseudo random numbers to sample points on the model surface, which makes the retrieve precision low and the result unstable. This paper proposes a method which employs quasi random sequence to sample points on the model surface. More uniformly distributed random sequences in zone [0, 1] are generated based on Halton sequence, and transformed into the proper sequences in the sampling space. The 3D model retrieve experimental results show that the retrieve efficiency is improved by using this method.
