The MeshDomain class provides geometrical information concerning the Mesh. It is called during surface meshes optimization to figure out the surface normal, how to snap vertices back to the surface, etc... .

Get degrees of freedom in vertex movement.
Given a vertex, return how the domain constrains the location of that vertex as the number of degrees of freedom in the motion of the vertex. If the domain is a geometric domain, the degrees of freedom for a vertex is the dimension of the geometric entity the vertex is constrained to lie on (e.g. point = 0, curve = 1, surface = 2, volume = 3.)
Implemented in ParaboloidDomain.

| virtual void MBMesquite::MeshDomain::snap_to | ( | Mesh::VertexHandle | entity_handle, |
| Vector3D & | coordinate | ||
| ) | const [pure virtual] |
Modifies "coordinate" so that it lies on the domain to which "entity_handle" is constrained. The handle determines the domain. The coordinate is the proposed new position on that domain.
Implemented in MBMesquite::DomainClassifier, MBMesquite::CircleDomain, MBMesquite::MsqIGeom, MBMesquite::PlanarDomain, MBMesquite::LineDomain, MBMesquite::XYRectangle, ParaboloidDomain, MBMesquite::ConicDomain, MBMesquite::SphericalDomain, MBMesquite::CylinderDomain, MBMesquite::XYPlanarDomain, MBMesquite::PointDomain, and MBMesquite::MsqIRel.

| virtual void MBMesquite::MeshDomain::vertex_normal_at | ( | Mesh::VertexHandle | entity_handle, |
| Vector3D & | coordinate | ||
| ) | const [pure virtual] |
Returns the normal of the domain to which "entity_handle" is constrained. For non-planar surfaces, the normal is calculated at the point on the domain that is closest to the passed in value of "coordinate". If the domain does not have a normal, or the normal cannot be determined, "coordinate" is set to (0,0,0). Otherwise, "coordinate" is set to the domain's normal at the appropriate point. In summary, the handle determines the domain. The coordinate determines the point of interest on that domain.
