Member Function Documentation

static short GetBoundaryPatchRingsize ( )

inlinestatic

Ringsize of Boundary Patches in table.

Definition at line 376 of file patchTables.h.

static short GetCornerPatchRingsize ( )

inlinestatic

Ringsize of Boundary Patches in table.

Definition at line 379 of file patchTables.h.

unsigned int const * GetFaceVertices ( int level = 0 ) const

inline

Returns a pointer to the vertex indices of uniformly subdivided faces.

In uniform mode the PatchTablesFactory can be set to generate either a patch array containing the faces at the highest level of subdivision, or a range of arrays, corresponding to multiple successive levels of subdivision.

Note : level '0' is not the coarse mesh. Currently there is no path in the factories to convert the coarse mesh to PatchTables.

Parameters

level the level of subdivision of the faces (returns the highest level by default)

Returns: a pointer to the first vertex index or NULL if the mesh is not uniformly subdivided or the level cannot be found.

Definition at line 744 of file patchTables.h.

FVarPatchTables const* GetFVarPatchTables ( ) const

inline

Returns the face-varying patches.

Definition at line 434 of file patchTables.h.

static short GetGregoryPatchRingsize ( )

inlinestatic

Ringsize of Gregory (and Gregory Boundary) Patches in table.

Definition at line 382 of file patchTables.h.

int GetMaxValence ( ) const

inline

Returns max vertex valence.

Definition at line 391 of file patchTables.h.

int GetNumControlVertices ( ) const

inline

Returns the total number of control vertex indices in the tables.

Definition at line 693 of file patchTables.h.

int GetNumFaces ( int level = 0 ) const

inline

Returns the number of faces in a uniformly subdivided mesh at a given level.

In uniform mode the PatchTablesFactory can be set to generate either a patch array containing the faces at the highest level of subdivision, or a range of arrays, corresponding to multiple successive levels of subdivision.

Note : level '0' is not the coarse mesh. Currently there is no path in the factories to convert the coarse mesh to PatchTables.

Parameters

level the level of subdivision of the faces (returns the highest level by default)

Returns: the number of faces in the mesh given the subdivision level or -1 if the mesh is not uniform or the level is incorrect.

Definition at line 756 of file patchTables.h.

int GetNumPatches ( ) const

inline

Returns the total number of patches stored in the tables.

Definition at line 795 of file patchTables.h.

Definition at line 310 of file patchTables.h.

PatchTables::PatchArray const * GetPatchArray ( int level = 0 ) const

inline

brief Returns a pointer to the PatchArry of uniformly subdivided faces at 'level'

Parameters

level the level of subdivision of the faces (returns the highest level by default)

Returns: a pointer to the PatchArray or NULL if the mesh is not uniformly subdivided or the level cannot be found.
