PatchVec Class Reference

#include <patch.h>

Class Description

See also

Class PatchMesh, Patches and Faces.

Description:

This class represents a patch vector. This can be either an interior vector or an edge vector. All methods of this class are implemented by the system.

Data Members:

Point3 p;

The vertex location.

int vert;

The vertex which owns this vector.

IntTab patches;

These are the patches that share this vector. If the edge is open there will only be one patch. In this case patches[0] will be used and patches[1] will be -1. Note: As of R4.0 the previous array of [2] has been replaced with the IntTab because vectors can now be used by more than two patches.

DWORD flags;

The patch vector flag:

PVEC_INTERIOR

This indicates the vector is an interior vector. These are the three vectors inside a tri patch or the four inside a quad patch.

int aux1;

This data member is available in release 3.0 and later only.

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

int aux2;

This data member is available in release 3.0 and later only.

Used to track topology changes during editing (PatchMesh).
