Detailed Description

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... .

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

pure 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'

Implemented in GeomEntTSTT, DomainTSTT, SphericalDomain, SphericalDomain, PlanarDomain, and PlanarDomain.

Here is the caller graph for this function:

virtual DomainHint hint ( ) const

pure 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.

Implemented in GeomEntTSTT, DomainTSTT, PlanarDomain, PlanarDomain, SphericalDomain, and SphericalDomain.

Referenced by MeshSet::get_next_elem_on_vert_patch(), and MeshSet::get_next_global_patch().

Here is the caller graph for this function:

virtual void normal_at	(	Mesh::EntityHandle	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.

Implemented in GeomEntTSTT, DomainTSTT, SphericalDomain, SphericalDomain, PlanarDomain, and PlanarDomain.

Referenced by PatchData::get_domain_normal_at_element(), PatchData::get_domain_normal_at_vertex(), PatchData::get_domain_normals_at_corners(), and PatchData::update_cached_normals().

Here is the caller graph for this function:

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

pure 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.

Implemented in GeomEntTSTT, DomainTSTT, SphericalDomain, SphericalDomain, PlanarDomain, and PlanarDomain.

virtual void snap_to	(	Mesh::EntityHandle	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 GeomEntTSTT, DomainTSTT, SphericalDomain, SphericalDomain, PlanarDomain, and PlanarDomain.
