Class Description

See also
Class Patch, Class PatchVec, Class PatchEdge, Class PatchVert, Class BitArray, Class TessApprox, Class PatchTVert, Patches and Faces.

Description:
A patch mesh can be made up of any number of patches. Each of these patches can be three or four sided. Each edge of a patch can only be used by either one patch (which makes it an open edge) or two patches (which makes it a transitional edge between the two).

All methods of this class are implemented by the system.
Topology:
int numVerts;

The number of vertices.

int numVecs;

The number of vectors.

int numPatches;

The number of patches.

int numEdges;

The number of edges.

Patch *patches;

The list of patches.

PatchVec *vecs;

The list of PatchVecs.

PatchEdge *edges;

The list of PatchEdges.

Tab<HookPoint> hooks;

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

This table is used internally
Geometry:
PatchVert *verts;

The list of PatchVerts.
Texture Coordinate Assignment:
Tab<int> numTVerts;

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

A table containing the number of texture vertices for each channel.

Tab<PatchTVert *> tVerts;

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

A table containing pointers to the texture vertices for each channel.

Previous to R4.0 this was a Tab<UVVert *>.

Tab<TVPatch *> tvPatches;

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

A table containing pointers to the texture vertex patches for each channel.
Material Assignment:
DWORD mtlIndex;

The object level material.
Selection:
BitArray vertSel;

The selected vertices.

BitArray edgeSel;

The selected edges.

BitArray patchSel;

The selected patches.

int bezVecVert;

This is used internally.

DWORD dispFlags;

The display attribute flags. See Patch Flags.

DWORD selLevel;

The current selection level. One of the following values:

PATCH_OBJECT - Object level.

PATCH_VERTEX - Vertex level.

PATCH_PATCH - Patch level.

PATCH_EDGE - Edge level.

int cacheSteps;

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

The meshSteps used for the cache.

BOOL cacheAdaptive;

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

The adaptive switch used for the mesh cache.

Tab<Point3> extrudeDeltas;

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

This data member is for internal use only.

Tab<ExtrudeData> extrudeData;

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

This data member is for internal use only.

Constructor & Destructor Documentation

Remarks
Constructor. Initializes data members (see Init() below).
CoreExport PatchMesh ( PatchMesh fromPatch)
Remarks
Constructor. This PatchMesh is initialized from the specified PatchMesh.
Remarks
Destructor. Frees up allocated arrays.

Member Function Documentation

CoreExport int HookFixTopology ( )
CoreExport void Init ( )
Remarks
Initializes the data members to default values.
CoreExport PatchMesh& operator= ( PatchMesh fromPatchMesh)
Remarks
Assignment operator from another PatchMesh.
CoreExport PatchMesh& operator= ( Mesh fromMesh)
Remarks
Assignment operator. This operator will do the conversion from a Mesh to a PatchMesh. Note that this can get very slow if there are a lot of faces in the mesh. When the system does the conversion is must do a fair amount of work with its interior connection lists. It builds a data base of what is connected to what and makes sure that the PatchMesh doesn't have any places where an edge is used by more than two patches. Also, for every face in the mesh it generates a triangular patch. Therefore use this method with some caution as it can create some very complex PatchMesh objects.
CoreExport void CopyPatchDataFrom ( PatchMesh fromPatchMesh)
Remarks
This method is available in release 3.0 and later only.

The following is similar to operator=, but just takes the major components, not the display flags, selection level, etc.
Parameters:
PatchMesh &fromPatchMesh

The patch mesh to copy from.
CoreExport BOOL setNumVerts ( int  ct,
BOOL  keep = FALSE 
)
Remarks
Sets the number of vertices in the patch mesh.
Parameters:
int ct

The new number of vertices.

BOOL keep = FALSE

If TRUE any old vertices are copied to the new array; otherwise they are freed.
Returns
TRUE if the number of vertices was allocated; otherwise FALSE.
int getNumVerts ( void  )
inline
Remarks
Returns the number of vertices in the patch mesh.
1302 { return numVerts; }
int numVerts
Definition: patch.h:1202
void setVert ( int  i,
const Point3 xyz 
)
inline
Remarks
Sets the 'i-th' vertex.
Parameters:
int i

The index of the vertex to set.

const Point3 &xyz

The vertex location.
1310 { verts[i].p = xyz; }

The index of the vertex to set.

float x, float y, float z

The vertex location.

Parameters:
int i

The index of the vertex to retrieve.
1323 { return verts[i]; }
PatchVert * verts
Definition: patch.h:1222

PatchVert * verts
Definition: patch.h:1222
CoreExport BOOL setNumVecs ( int  ct,
BOOL  keep = FALSE

Sets the number of map patches in the original TV or vertex color channels. (Note that setNumMapPatches() is called from setNumPatches(), so this doesn't need to be called separately once a map channel is active.)

If the map patches are non-NULL and ct = 0 they are set to NULL (and freed)

CoreExport BOOL buildLinkages ( int  patch = -1)
Remarks

This option is available in release 4.0 and later only.

This optional parameter allows you to only update adjacency information for a single new patch. If the plugin code is adding new patches and not removing any others then you can call this method with the new patch index and the various adjacency information in vertices, vectors, and edges will be built. If you call this method for the entire object (no parameter or patch < 0) it will destroy all adjacency information and rebuild it from scratch.

CoreExport BitArray VertexTempSel ( )
Remarks
Constructs a vertex selection list based on the current selection level. For example if the selection level is at object level all the bits are set. If the selection level is at vertex level only the selected vertex bits are set. See Class BitArray.
CoreExport void ApplyConstraints ( BOOL  selOnly = FALSE)
Remarks
This method may be called to apply the coplanar constraints to the patch mesh. The constraints may optionally only apply to selected vertices. There is a flag that may be set for a patch vertex (PVERT_COPLANAR). For example, you can set this flag to make a vertex coplanar with its vectors. If this is done, then when this method is called, the patch code will then go through the PatchMesh and find the average plane that is used by the vertex and all the vectors associated with it. It will then constrain all the vectors to lie in this plane (by rotating them so that they lie on the plane). In this way there will be a consistent transition between the patches sharing the vertex.
Parameters:
BOOL selOnly = FALSE

If TRUE the constraints are only applied to the selected vertices; otherwise all vertices.

CoreExport void AutoSmooth ( float  angle,
BOOL  useSel,
BOOL  preventIndirectSmoothing 
)
Remarks
This method is available in release 4.0 and later only.

This method will perform automatic smoothing on the patch mesh. The smoothing angle is determined for each patch by computing the normals at each corner of the patch (using the corner vertex and the two edge vectors connected to that vertex), then averaging the normals of the two corners of each edge to arrive at a normal for that edge. These normals are used to determine whether adjacent patches are within the auto-smooth threshold angle.
Parameters:
float angle

The minimum angle between surface normals for smoothing to be applied, in radians.

BOOL useSel

If this parameter is set to TRUE then only the selected patches are smoothed.

BOOL preventIndirectSmoothing

TRUE to turn on; FALSE to leave it off. This matches the option in the Smooth Modifier UI – use this to prevent smoothing 'leaks" when using this method. If you use this method, and portions of the patch mesh that should not be smoothed become smoothed, then try this option to see if it will correct the problem. Note that the problem it corrects is rare, and that checking this slows the automatic smoothing process.
