MeshStats

Description

MeshStats is a program that prints various statistics about a surface mesh like resolution, bounding box and numbers of elements.

Files

MeshStats.c is the controlling function. It reads in the mesh and calls the function to compute the mesh statistics.

Usage

By typing 'MeshStats -' the following options (format description default) are printed:

Usage: MeshStats (see MeshStats.html for complete usage)

%S in mesh filename [required]

Detailed Usage

%S in mesh filename [required]

The name of the VRML indexed face set filename that you would like to analyze.

Examples

To print the statistics of a mesh valve.model.wrl enter:

MeshStats valve.model.wrl

Something like the following will be printed

  MESH STATISTICS 
  Number of meshpoints: 2433 
  Number of meshedges: 7329 
  Number of meshfaces: 4886 
  Mesh Resolution: 0.0268777 
  Average meshedge length: 0.0265886 
  StDev meshedge length: 0.00686257 
  Spread of length: 25.8102% 
  Max meshedge length: 0.0740893 
  Min meshedge length: 0.00825793 
  Bounding Box Minimum: -0.4925 -0.8375 -0.175 
  Bounding Box Maximum: 0.1775 0.035 0.174998 

Mesh resolution is the median edge length of all edges in the mesh. The bounding box is aligned with the XYZ axes of world coordinates. When the spread of length is small (25%) then the surface described is more or less uniformly sampled by the mesh. The rest of the mesh statistics are self explanatory.
