Detailed Description

template<class Basis>
class SCIRun::StructQuadSurfMesh< Basis >

Declarations for virtual interface.

Functions for creating the virtual interface Declare the functions that instantiate the virtual interface

These declarations are needed for a combined dynamic compilation as as well as virtual functions solution. Declare that these can be found in a library that is already precompiled. So dynamic compilation will not instantiate them again.

If there are no nodes we cannot find the closest one

Test the one in face that is an initial guess

As we computed an estimate, we use the Newton's method in the basis functions compute a more refined solution. This function may slow down computation. This piece of code will calculate the coordinates in the local element framework (the newton's method of finding a minimum), then it will project this back THIS CODE SHOULD BE FURTHER OPTIMIZED

This looks incorrect - but it is correct We need to do a full shell without any elements that are closer to make sure there no closer elements in neighboring searchgrid cells
