Detailed Description
calculate quality of tetrahedral meshes
- Date:

2002/10/22 16:02:39
- Revision:
-
1.3
vtkMeshQuality will calculate the normalized quality ratio of the cells in a tetrahedral mesh according to the equation:
ratio = (radius of circumscribed sphere)/(radius of inscribed sphere)/3.
The minumum (and ideal) quality ratio is 1.0 for regular tetrahedra, i.e. all sides of equal length. Larger values indicate poorer mesh quality. The resulting quality values (and the tetrahedron volumes) are set as the Scalars of the FieldData of the output.
