Detailed Description

Constructor & Destructor Documentation

SYS_FORCE_INLINE GU_PrimPoly::GU_PrimPoly ( GA_Detail gdp,
GA_Offset  offset = GA_INVALID_OFFSET 
)
inline

NOTE: This constructor should only be called via GU_PrimitiveFactory.

Definition at line 50 of file GU_PrimPoly.h.

SYS_FORCE_INLINE GU_PrimPoly::GU_PrimPoly ( GA_Detail gdp,
GA_Offset  offset,
const GA_OffsetListRef vertex_list 
)
inline

This constructor is for making a representation of a polygon on the stack, so that you can call GU_PrimPoly functions on the polygon without needing the detail to allocate one.

inline

Given a bit array representing the edges in the poly (1 meaning delete and 0 meaning keep) delete as many edges as possible. If a particular edge cannot be deleted then negate the value in removededges[edgenum]. DO NOT CHANGE THE MAGNITUDE! Returns 0 if successful, -1 if the poly becomes degenerate, and -2 if the poly should be removed. The signature for this method is consistent with those in other classes, but note that there is never a case where an edge cannot be removed from a polygon.

Definition at line 138 of file GU_PrimPoly.h.

int GU_PrimPoly::removeEdges ( const UT_BitArray edgemap,
GEO_Face *&  newpoly,
bool  del_bridges = true 
)

Same as above method, but instead of accepting an (unused) array of edge indices, it returns one (possibly one of many) polygons created because this polygon had to be split.

int GU_PrimPoly::removeEdges ( const UT_BitArray edgemap,
UT_Array< GEO_Face * > &  newpoly,
bool  del_bridges = true 
)

Same as above, but it returns all polygons created because of polysplit.
