一种基于约束Delaunay四面体剖分的四面体网格射线追踪方法

onventional ray tracing (RT) techniques face an obvious shortage of slow performance. Several acceleration methods have been proposed to address this problem and the tetrahedron meshed ray tracing (TMRT) method is verified superior to others in specific scenarios. In the TMRT method, Tetrahedralization is first required to preprocess the original scenario to trace rays through it. In this paper, we propose a TMRT method based on constrained Delaunay tetrahedralization. Compared with other RT method, the voxel method, we will see a marked acceleration effect of TMRT. We will also compare the CDT method with other tetrahedralization method to illustrate the impact of tetrahedralization on the TMRT acceleration effect in different scenarios.
