Interactive Visualization of Large and Arbitrary Polygonal and Polyhedral Meshes with OpenGL 4

This paper describes an efficient strategy to visualize polygons and polyhedra using OpenGL 4 flexibility. Such meshes offer flexibility as the number of vertices and faces are arbitrary. Dual meshes are examples of polygonal and polyhedral meshes. We give explanations on how polygons and polyhedra can efficiently be stored in mesh files. Algorithms to tessellate polygons into triangles are described. Many examples and comparisons with another visualization software show that our methodology is efficient (about 40 times faster than ParaView). Interactivity is also ensured with post-processing tools such as picking and cut planes.
