This study introduces FastMesh, an efficient framework for generating interactive level-of-detail (LOD) for large triangle meshes. It enables real-time, view-dependent mesh simplification with minimal visual artifacts.

Area of Science:

  • Computer Graphics
  • Geometric Modeling

Background:

  • Multiresolution mesh representations are crucial for managing complexity in interactive rendering.
  • View-dependent simplification is ideal for interactive visualization, adapting to user perspective.

Purpose of the Study:

  • To present FastMesh, an efficient, topology-preserving multiresolution meshing framework.
  • To enable interactive level-of-detail (LOD) generation and real-time mesh simplification.

Main Methods:

  • Developed a hierarchical multiresolution triangulation framework using a half-edge data structure.
  • Implemented optimized view-dependent and visual mesh simplification heuristics.

Main Results:

  • FastMesh achieves efficient, view-dependent LOD generation and real-time mesh simplification.
