3D geometric model region partition method

Focusing on detail preserving in triangle mesh model simplification, a novel 3D geometric model region partition method based on self-organizing feature map is proposed. Firstly, computing the character vector of each vertex of 3D geometric model. Next, segmenting 3D geometric model preliminarily based on self-organizing feature map. Finally, merging over-segmentation regions used max-relativity rule and getting the last result. Experiment shows that this approach is effective and meets the requirement of keeping local features in model simplification.
