Detailed Description
- See also:
- Class PatchMesh,
Working with
Patches.
- 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).

Constructor & Destructor Documentation
| CoreExport PatchVec | ( | ) |
- Remarks:
- Constructor. The location is set to 0,0,0. The vertex owner is set to undefined. The patches using the vector is set to undefined. The flags are set to 0.
- Remarks:
- Constructor. The data members are initialized to those of the from patch vector.
- Parameters:
- PatchVec
&from
The vector to copy from.
Member Function Documentation
| void ResetData | ( | ) | [inline] |
| CoreExport BOOL AddPatch | ( | int | index | ) |
- Remarks:
- Adds the specified patch to this vector table.
- Parameters:
- int index
The index in the PatchMesh class patches table (patches) of the patch to add.
- Returns:
- Returns TRUE if the patch was added; otherwise FALSE.
- Remarks:
- Assignment operator.
- Parameters:
- PatchVec&
from
The patch vector to copy from.
| void Transform | ( | Matrix3 & | tm | ) | [inline] |
- Remarks:
- This method is available in release 3.0 and later only.
Transforms the vertex location p by the specified matrix.
- Parameters:
- Matrix3
&tm
The matrix to transform the vertex.
- Remarks:
- This is used internally to save the data to the .MAX file.
- Remarks:
- This is used internally to load the data from the .MAX file.
