Abstract

The mesh approximation of solid models is an important and necessary step for several applications. Particularly when surfaces with T-junctions are presented in the model. In this situation, the surface boundaries can have different number of segment approximations. Such a surface can be filled by an irregular mesh. The paving algorithm is one of the best mesh generators, however its implementation is not easy. This work redesign the paving algorithm with a specific implementation to mesh quadrilaterals with different segmentaion in each side. Several results are shown demonstrating that the redesigned paving algorithm was successfully implemented.
