Member Function Documentation

virtual void UT_Convex::beginPolygon	(	int	npoints,
		bool	lastone
	)

pure virtual

beginPolygon will be told when the last polygon is being added

Implemented in GU_TrimTesselator.

static bool UT_Convex::canSplitQuad02	(	const UT_Vector3 &	p0,
		const UT_Vector3 &	p1,
		const UT_Vector3 &	p2,
		const UT_Vector3 &	p3
	)

inlinestatic

Returns true if splitting the specified quad along the line from point 0 to point 2 is possible

Definition at line 68 of file UT_Convex.h.

void UT_Convex::convex	(	exint	maxsides,
		bool	allowinterrupt = `true`,
		bool	avoiddegeneracy = `false`
	)

virtual void UT_Convex::earlyTermination ( )

virtual

If the last polygon to be added won't be added after all, e.g. if it is degenerate and avoiddegeneracy is true, the earlyTermination() method will be called. This is so that the caller can clean up properly, since beginPolygon will not have been called with lastone==true. By default, this method does nothing.

virtual void UT_Convex::endPolygon ( )

pure virtual

Implemented in GU_TrimTesselator.

virtual int64 UT_Convex::getMemoryUsage ( bool inclusive ) const

virtual

Reimplemented in GU_TrimTesselator.

virtual void UT_Convex::getPoint	(	int	num,
		float &	x,
		float &	y
	)		const

pure virtual

Implemented in GU_TrimTesselator.

virtual int UT_Convex::getPointCount ( ) const

pure virtual

It's the sub-class responsibility to fill these out...

Implemented in GU_TrimTesselator.

virtual void UT_Convex::initialize ( )

virtual

bool UT_Convex::isConcave ( )

static bool UT_Convex::isQuadConvex	(	const UT_Vector3 &	p0,
		const UT_Vector3 &	p1,
		const UT_Vector3 &	p2,
		const UT_Vector3 &	p3
	)

inlinestatic

Returns true if the specified quad is convex. NOTE: This may return false negatives for highly non-planar quads, since the definition of convex breaks down.

Definition at line 84 of file UT_Convex.h.

virtual void UT_Convex::polyVertex ( int num )

pure virtual

Implemented in GU_TrimTesselator.

UT_Convex::UT_NON_COPYABLE ( UT_Convex )
