Member Function Documentation

void GU_Cookie::addPointToGroup	(	GEO_Point *	pt,
		GEO_PrimPoly *	poly
	)

UT_IntArray* GU_Cookie::buildConnectivityGraph

(

)

void GU_Cookie::buildTrimSegments	(	GEO_PrimPoly *	dst,
		GEO_PrimPoly *	src
	)

This adds all the isects of the second polygon into the trim list of the first:

void GU_Cookie::buildTrimSegmentsCoplanar	(	GEO_PrimPoly *	dst,
		GEO_PrimPoly *	src,
		bool	reverse
	)

void GU_Cookie::classifyPolygons	(	const GB_PrimitiveGroup &	originalgrp,
		GB_PrimitiveGroup &	ingrp,
		GB_PrimitiveGroup &	outgrp,
		GB_PrimitiveGroup &	overlapgrp,
		UT_IntArray *	edges,
		const GB_PrimitiveGroup &	othergrp,
		GU_RayIntersect *&	inter,
		bool	insidetest,
		bool	inter_closed
	)

void GU_Cookie::cookie	(	GU_Detail &	gdp,
		int	generatecrease,
		GB_PrimitiveGroup &	aingrp,
		GB_PrimitiveGroup &	aoutgrp,
		GB_PrimitiveGroup &	aoverlapgrp,
		int	aclosed,
		GB_PrimitiveGroup &	bingrp,
		GB_PrimitiveGroup &	boutgrp,
		GB_PrimitiveGroup &	boverlapgrp,
		int	bclosed,
		int	insidetest
	)

Invoke the cookie operation.

The group of polygons to cookie must be setup with the setGroups function.

The [a|b][in|out|overlap]grps are the primitive groups to classify each clipped polygon piece into.

If a set of connected polygons doesn't intersect, and the insidetest is enabled, the insidedness of the polygons will be determined by sending a ray with the winding rule.

If generatecrease is set, instead of clipping the polygons, the line segments generated by poly-poly intersection will be generated.

GEO_Vertex* GU_Cookie::createEdgeVertex	(	guTrimInfo *	base,
		int	edge,
		float	t,
		int	dir
	)

The edge is poly(edge-1) to poly(edge).

GEO_Vertex* GU_Cookie::createInteriorVertex	(	guTrimInfo *	base,
		const UT_Vector3 &	pt
	)

GEO_PrimPoly* GU_Cookie::createPoly	(	guTrimInfo *	base,
		const UT_PtrArray< GEO_Vertex * > &	vtxes,
		bool	closed,
		bool	preserve_groups = true
	)

void GU_Cookie::performIsect	(	int	primIdA,
		int	primIdB
	)

The call back from intersection tests: The two indices are the primitive numbers to intersect.

void GU_Cookie::punchHole	(	GEO_PrimPoly *	base,
		GEO_PrimPoly *	hole
	)

Punches a hole in the polygon base with the polygon hole. The appropriate bridges are formed.
