Class PatchEdge

Class PatchEdge

See Also: Class PatchMesh, Working with Patches.

class PatchEdge

Description:

This class describes a patch edge using the vertices at the edge ends, and the indices of the patches sharing the edge. All methods of this class are implemented by the system.

Data Members:

public:

int v1;

Index of the first vertex.

int vec12;

Vector from v1 to v2.

int vec21;

Vector from v2 to v1.

int v2;

Index of second vertex.

IntTab patches;

Index of the patches using this edge. If the edge is only used by one patch, patches[1] will be less than zero. Note: Previous to R4.0 two separate integer variables (patch1 and patch2) were used.

int aux1;

This is used to track topology changes during editing (Edit Patch).

int aux2;

This is used to track topology changes during editing (PatchMesh).

Methods:

Prototype:

PatchEdge();

Remarks:

Constructor. The data members are initialized as undefined.

Prototype:

PatchEdge(PatchEdge &from);

Remarks:

Constructor. The data members are initialized from the PatchEdge passed.

Prototype:

PatchEdge(int v1, int vec12, int vec21, int v2, int p1, int p2, int aux1=-1, int aux2=-1);

Remarks:

Constructor. The data members are initialized to the values passed.

Prototype:

IOResult Save(ISave* isave);

Remarks:

This is used internally to save the data to the .MAX file.

Prototype:

IOResult Load(ILoad* iload);

Remarks:

This is used internally to load the data from the .MAX file.

Prototype:

void Dump();

Remarks:

You may call this method to dump the patch edge structure via DebugPrint(). See Debugging.
