An improved subdivision algorithm using for heart model
2012
In this paper, we use a three-dimensional heart model which is reconstructed by cloud points. As the need of post-processing such as adding ablation line and opening on the model, we have to subdivide the grid model. After analyzing the characters of the model, basing on the loop algorithm, we propose a method in which we subdivide a triangle into 16 triangles, and through the experiment we get a very uniform sub-grid model and a much more smoothly 3D heart surface model. In this paper we also make a contrast by opening on the original model and the subdivided model, and we find the cross-section on subdivided model is much more smoothly. The speed of the postprocessing on the subdivided model also meets the needs of the project very well.
