FIELD3D_NAMESPACE_OPEN bool isPointInField(const FieldRes::Ptr f, const V3d &wsP)
Checks whether the point is within the given field.
bool isLegalVoxelCoord(const V3d &vsP, const Box3d &vsDataWindow)
Checks whether the floating - point voxel coordinate is within the given (floating point) data window...
Contains the FieldInterp base class and some standard interpolation classes.
