/*
|
|
* Mesh quality metric functions that compute the shape, or weighted Jacobian, of mesh cells.
|
|
* The Jacobian of a cell is weighted by the condition metric value of the cell.
|
|
** These metric computations are adapted from the VTK implementation of the Verdict library,
|
|
* which provides a set of 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)
