Abstract

Mesh Boolean is a basic operation in mesh modeling and the remeshing method is the key technology. This paper proposed an adaptive remeshing method with the hybrid of local edge length and curvature information, for high quality and efficient mesh Boolean in multi-resolutions. Firstly, calculate the local control length according to local edge length and curvature information. Then split too long edges, collapse too short edges, flip edges to minimize vertex valance, relax vertex position in tangent plane, project it back to the initial mesh. Iterate upper five steps to complete remeshing. Finally, to prove the efficiency and better control of mesh resolutions of the proposed algorithm, compare it with two art-to-date remeshing methods, using the models of dataset Thingi10k and apply it to an adaptive mesh Boolean method. The result shows that the average length is 55% shorter in high curvature area and 78% longer in low curvature area compared with uniform remeshing.
