After the stage of higher tailoring, the candidate triangle pairs are still need to be further reduced to eliminate redundant tests in the stage of lower tailoring.This paper aims to propose a method to improve performance and efficiency in lower tailoring for self-collision detection of arm cloth simulation.Lower tailoring is a primitive level of cutting off redundant and non-colliding primitive pairs.Our method includes two stages.Firstly this paper eliminate redundant primitive pairs and remove non-intersecting primitive pairs by carrying out feature-based distribution and making intersection test of primitive bounding box.Secondly a non-coplanar filter is used to filter out non-coplanar primitive pairs within time step through non-coplanar test which further reduce candidate primitive pairs.Test results show that, our method can effectively remove redundant and non-colliding primitive pairs and has, to some extent, improved the efficiency for self-collision detection.
