A Hidden Surface Removal Algorithm for 3D Finite Element Meshes
Qing Yang · Mechanical Science and Technology · 2004
The commonly used hidden line and/or hidden surface removal algorithms are unsatisfactory in 3D finite element meshes rendering, as they are less efficient due to the lack of consideration of relativity of 3D finite element meshes. In this paper, the relativity of 3D finite element meshes is discussed and an efficient hidden surface removal algorithm based on the relativity is presented. Contiguous surfaces among finite element meshes are removed before rendering by quick sorting algorithm. With the amount of data to be rendered is minimized, the rendering speed increases remarkably. The algorithm is put into practice and the result shows that it is an efficient hidden surface removal approach for 3D finite element meshes.
