Detailed Description

See also
Class PatchMesh, Template Class Tab, Patches and Faces.
Description:
This class stores the information associated with a patch vertex and provides methods to access the data associated with this vertex. All methods of this class are implemented by the system.
Data Members:
Point3 p;

The vertex location.

IntTab vectors;

The list of vectors attached to this vertex. There can be any number of vectors attached to a vertex. For example consider the north pole of a sphere made from a set of triangular patches. If there were 16 patches meeting at this point there would be 16 vectors. The table contains the indices of these vectors. This is set up automatically when a developer calls buildLinkages().

Note: typedef Tab<int> IntTab;

Note that the methods below allow a developer to manipulate the tables of this class. Developers must be careful when doing so as it is easy to corrupt the patch data structures. It may be easier for developers to manipulate the patches, delete vertices, etc., by manipulating them in the PatchMesh and then call buildLinkages() again. The methods below do work however and may be used.

IntTab patches;

The list of patches using this vertex.

IntTab edges;

This data member is available in release 4.0 and later only.

The list of edges using this vertex. This table will be set up automatically when a developer calls buildLinkages().

DWORD flags;

The patch vertex flags

PVERT_COPLANAR

This constrains things such that this vertex and all the vectors that are attached to it are coplanar. If this is set, and you call ApplyConstraints(), the system will adjust the vectors to the average plane that they are in and then constrain them to it.

PVERT_CORNER

The vertex is a corner.

PVERT_HIDDEN

The vertex is hidden.

int aux1;

Used to track topo changes during editing (Edit Patch).

int aux2;

Used to track topology changes during editing (PatchMesh).
