SimplifyMesh[mesh]

simplifies the mesh region mesh by reducing the number of polygons and keeping the overall shape.

SimplifyMesh[mesh,crit]

reduces the number of polygons using the specified criteria crit.

Details

  • SimplifyMesh is also known as mesh decimation or level-of-detail generation (LOD).
  • SimplifyMesh is typically used to reduce the complexity of a geometric model by decreasing the number of polygons or vertices while preserving its overall shape, improving rendering, processing and analysis.
  • SimplifyMesh[mesh] returns a mesh region obtained by reducing the number of polygons of mesh.
  • SimplifyMesh[mesh,crit] returns a mesh region satisfying the specified criteria crit.
  • Possible criteria crit include:
  • {"MaxVertexCount",n}at most n vertices
    {"MaxEdgeCount",n}at most n edges
    {"MaxTriangleCount",n}at most n triangles
    {"MaxIncidentEdgeCount",n}at most n incident edges to a vertex
  • For n between 0 and 1, SimplifyMesh[mesh,{type,n}] simplifies a mesh with approximate size proportion n of type.
  • Possible criteria crit for minimal cells measures include:
  • {"MinEdgeLength",l}minimal edge length
    {"MinTriangleArea",a}minimal triangle area
  • Possible mesh structural criteria crit include:
  • {"TriangleQuality",q}square of the maximal edge length over area
    {"MaxNormalDeviation",d}maximal ....
    {"MaxHausdorffDistance",d}maximal Hausdorff distance from the given mesh
