Detailed Description

This is a template for a planar domain that exists in the xy-plane (z=0). It will provide the normal information necessary for surface mesh optimization.

void MBMesquite::XYPlanarDomain::closest_point ( Mesh::VertexHandle  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_handleEvaluate the subset of the domain contianing this entity
positionInput position for which to evaluate
closestClosest position in the domain.
normalDomain normal at the location of 'closest'

}
void MBMesquite::XYPlanarDomain::snap_to ( Mesh::VertexHandle  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.

Implements MBMesquite::MeshDomain.

Definition at line 37 of file XYPlanarDomain.cpp.

{
    coordinate[2] = 0.0;
}
void MBMesquite::XYPlanarDomain::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:
handlesThe domain evaluated is the one in which this mesh entity is constrained.
coordinatesAs input, a list of positions at which to evaluate the domain. As output, the resulting domain normals.
countThe length of the coordinates array.
