Member Function Documentation

void closest_point ( Mesh::EntityHandle  handle, const Vector3D &  position, Vector3D &  closest, Vector3D &  normal, MsqError &  err  ) const

virtual

evaluate closest point and normal

Given a position in space, return the closest position in the domain and the domain normal at that point.

Parameters

entity_handle	Evaluate the subset of the domain contianing this entity
position	Input position for which to evaluate
closest	Closest position in the domain.
normal	Domain normal at the location of 'closest'

Implements MeshDomain.

Here is the call graph for this function:

DomainHint hint ( ) const

virtual

Give a hint about the nature of the domain for better performance.

For implementations, if unsure, return NO_DOMAIN_HINT. SMOOTH_DOMAIN is a good default choice if the domain is a single geometric surface.

Implements MeshDomain.

Definition at line 348 of file GeomTSTT.cpp.

References Mesquite::SMOOTH_DOMAIN.

  { return SMOOTH_DOMAIN; }

void normal_at ( Mesh::EntityHandle  entity_handle, Vector3D &  coordinate  ) const

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.

User should see also PatchData::get_domain_normal_at_vertex and PatchData::get_domain_normal_at_element .

Implements MeshDomain.

Here is the call graph for this function:

void normal_at ( Mesh::EntityHandle  handle, Vector3D  coordinates[], unsigned  count, MsqError &  err  ) const

virtual

evaluate surface normals

Returns normals for a domain.

Parameters

entity_handle	The domain evaluated is the one in which this mesh entity is constrained.
coordinates	As input, a list of positions at which to evaluate the domain. As output, the resulting domain normals.
count	The length of the coordinates array.

Implements MeshDomain.

Here is the call graph for this function:

void snap_to ( Mesh::EntityHandle  entity_handle, Vector3D &  coordinate  ) const

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.
