Detailed Description

A MBMesquite::MeshDomain implemented on top of the ITAPS iGeom API.

Simple MeshDomain class implementatation that queries a single iGeom entity for all geometric queries. Suitable for use when the entire mesh to be smoothed lies on a single geometric surface.

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'

void MBMesquite::MsqIGeom::snap_to	(	Mesh::VertexHandle	entity_handle,

	)		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.

void MBMesquite::MsqIGeom::vertex_normal_at	(	Mesh::VertexHandle	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.

evaluate surface normals

Returns normals for a domain.

Parameters:

handles	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.
