Mesh Simplification Algorithms for Rendering Performance
Hongle Li, SeongKi Kim · International Journal of Engineering Research and Technology · 2020
In virtual worlds simulated by computers, all objects consist of complex 3D meshes, and it is important to simplify the meshes for rendering performance while maximally maintaining the original geometry.This research conducts a series of studies on the simplification of the triangular mesh model and proposes four different simplified algorithms and two hybrid algorithms.All of these algorithms are based on vertex aggregation, vertex removal, and iterative edge folding, and the common principle is to reduce vertex data in the original model that is not important to the model geometry.After reducing the data, the point cloud is retriangulated.This research implements these six algorithms and conducts an experiment.With the simplification algorithms in this paper, rendering performance improves by 25% ~ 35% while maintaining the geometry of the model to the greatest extent.To the best of our knowledge, the proposed algorithms in this paper (VT, FAD, SS, VTD, FASS) are the world-first.
