Member Function Documentation

virtual void GEO_PrimTube::addToBSphere

(

UT_BoundingSphere *

bsphere

)

const [virtual]

Enlarge the bounding sphere with the primitive's bounds. By default, this will enlarge the bounding sphere by the primitive's bounding box (i.e. getBBox()). It may be possible to have a tighter bound (i.e. the vertex hull for many primitives is a much better metric).

Reimplemented from GEO_Primitive.

static GA_PrimitiveFamilyMask GEO_PrimTube::buildFamilyMask

(

)

[inline, static, protected]

Return the family mask for all quadric sub-classes.

Reimplemented from GEO_Quadric.

Definition at line 136 of file GEO_PrimTube.h.

virtual fpreal GEO_PrimTube::calcArea

(

)

const [virtual]

If the method isn't known, or doesn't make sense, we return 0.

Reimplemented from GEO_Primitive.

virtual fpreal GEO_PrimTube::calcPerimeter

(

)

const [virtual]

If the method isn't known, or doesn't make sense, we return 0.

Reimplemented from GEO_Primitive.

virtual fpreal GEO_PrimTube::calcVolume

(

const UT_Vector3 &

)

const [virtual]

If the method isn't known, or doesn't make sense, we return 0.

Reimplemented from GEO_Primitive.

static float GEO_PrimTube::computeCaptureRegionWeight	(	const UT_Vector3 &	pos,
		float	bcap,
		float	tcap,
		float	taperx,
		float	taperz,
		float	min_weight,
		float	max_weight
	)			[static]

virtual GEO_Primitive* GEO_PrimTube::copy

(

int

preserve_shared_pts = 0

)

const [virtual]

Reimplemented from GEO_Quadric.

virtual void GEO_PrimTube::copyOffsetPrimitive	(	const GEO_Primitive *	src,
		int	basept
	)			[protected, virtual]

Reimplemented from GEO_Quadric.

virtual void GEO_PrimTube::copyPrimitive	(	const GEO_Primitive *	src,
		GEO_Point **	ptredirect
	)			[virtual]

Reimplemented from GEO_Quadric.

virtual void GEO_PrimTube::copyUnwiredForMerge	(	const GA_Primitive *	src,
		const GA_MergeMap &	map
	)			[virtual]

Copy the specified primitive as part of the merge. The source primitive will be of the same type.

Since the vertex offsets will change for the merged geometry, the map should be used to lookup the new vertex offsets. For example

    map.mapDestFromSource( GA_ATTRIB_VERTEX, source_vertex );

Reimplemented from GEO_Quadric.

unsigned GEO_PrimTube::endcaps

		GA_AttributeRefMap &	hlist,
		fpreal	u,
		fpreal	v,
		uint	du,
		uint	dv
	)			const [protected, virtual]

Implements GEO_Primitive.

virtual int GEO_PrimTube::evaluatePointV4	(	UT_Vector4 &	pos,
		float	u,
		float	v = 0,
		unsigned	du = 0,
		unsigned	dv = 0
	)			const [protected, virtual]

Evaluate the position for the given parametric coordinates (with the given derivatives). Return 0 if successful, or -1 if failure. The default implementation returns {0,0,0,0};

Reimplemented from GEO_Primitive.

virtual int GEO_PrimTube::getBBox

(

UT_BoundingBox *

bbox

)

const [virtual]

Compute the bounding box of the primitive. Return 0 if unable to compute bounds (1 on successful computation)

Implements GEO_Quadric.

		const GA_ROAttributeRef &	tubeCaptAtrOffset
	)			const

virtual const GA_PrimitiveJSON* GEO_PrimTube::getJSON

(

)

const [virtual]

This method returns the JSON interface for saving/loading the primitive If the method returns a NULL pointer, then the primitive will not be saved to geometry files (and thus cannot be loaded).

Implements GA_Primitive.
