Detailed Description

template<class ElemBasis>
class SCIRun::Core::Basis::Dim3Locate< ElemBasis >

Class for searching of parametric coordinates related to a value in 3d meshes and fields More general function: find value in interpolation for given value Step 1: get a good guess on the domain, evaluate equally spaced points on the domain and use the closest as our starting point for Newton iteration. (implemented in derived class) Step 2: Newton iteration. x_n+1 =x_n + y(x_n) * y'(x_n)^-1
