/*
|
|
* Mesh quality metric functions that compute the shape and size of a cell. This
|
|
* takes the shape metric and multiplies it by the relative size squared metric.
|
|
*
|
|
* These metric computations are adapted from the VTK implementation of the
|
|
* Verdict library, which provides a set of mesh/cell metrics for evaluating the
|
|
* geometric qualities of regions of mesh spaces.
|
|
*
|
|
* See: The Verdict Library Reference Manual (for per-cell-type metric formulae)
|
|
* See: vtk/ThirdParty/verdict/vtkverdict (for VTK code implementation of this
|
|
* metric)
