Member Function Documentation

int GU_Decompose::fillComponentIDAttribute ( GA_RWHandleI attrib)
GA_Offset* GU_Decompose::getBoundary ( int  idx,
int length 

Returns a pointer to an array of half-edges which form the boundary cycle of numbered idx among all boundary cycles.

int GU_Decompose::getBoundaryComponentID ( int  idx)

Returns index of the primitive component to which the idx-th boundary cycle belongs.

Iterator GU_Decompose::getBoundaryIterator ( int  bd)

int GU_Decompose::getBoundarySize ( int  idx)
int GU_Decompose::getBoundarySizesSum ( )
GA_Offset* GU_Decompose::getComponent ( int  idx,
int length 
GA_Offset* GU_Decompose::getComponentBoundary ( int  comp,
int  idx,
int length 

Returns a pointer to an array of half-edges which form the idx-th boundary cycle among all boundary chains for the patch comp. (first index is zero).

int GU_Decompose::getComponentNumBoundaries ( int  comp)

Returns the number of boundary components of a given component.

int GU_Decompose::getNumBoundaries ( )

Returns the total number of boundary chains (cycles) in all the components. Note that some components may have no boundary chains and other may have multiple. For a 2-manifold maximal patch, i.e. one made of primitives, each boundary chain is a closed cycle of edges. For a 1-manifold maximal patch, i.e. oen made of edges, the boundary chain (when non-empty) consists of the two endpoints.

int GU_Decompose::getNumComponents ( )

Returns the number of maximal manifold components.

bool GU_Decompose::isComponentClosed ( int  idx)
