Member Function Documentation

virtual void GEO_PrimSphere::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_PrimSphere::buildFamilyMask

(

)

[inline, static, protected]

Return the family mask for all quadric sub-classes.

Reimplemented from GEO_Quadric.

Reimplemented in GEO_PrimMetaBall, and GEO_PrimMetaSQuad.

Definition at line 72 of file GEO_PrimSphere.h.

virtual fpreal GEO_PrimSphere::calcArea

(

)

const [virtual]

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

Reimplemented from GEO_Primitive.

virtual fpreal GEO_PrimSphere::calcPerimeter

(

)

const [virtual]

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

Reimplemented from GEO_Primitive.

virtual fpreal GEO_PrimSphere::calcVolume

(

const UT_Vector3 &

)

const [virtual]

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

Reimplemented from GEO_Primitive.

virtual int GEO_PrimSphere::evaluateNormalVector	(	UT_Vector3 &	nml,
		float	u,
		float	v = 0
	)			const [virtual]

Reimplemented from GEO_Primitive.

virtual bool GEO_PrimSphere::evaluatePointRefMap	(	GA_Offset	result_vtx,
		GA_AttributeRefMap &	hlist,
		fpreal	u,
		fpreal	v,
		unsigned	du,
		unsigned	dv
	)			const [protected, virtual]

virtual int GEO_PrimSphere::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_PrimSphere::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.

virtual const GA_PrimitiveJSON* GEO_PrimSphere::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.

Reimplemented in GEO_PrimMetaBall, and GEO_PrimMetaSQuad.

virtual int64 GEO_PrimSphere::getMemoryUsage

(

)

const [virtual]

Report approximate memory usage.

Implements GA_Primitive.

Reimplemented in GEO_PrimMetaBall, and GEO_PrimMetaSQuad.

virtual void GEO_PrimSphere::getUnitBoundingBox

(

UT_BoundingBox &

box

)

const [protected, virtual]

Return a bounding box for the "unit" primitive (i.e. untransformed).

Implements GEO_Quadric.

virtual int GEO_PrimSphere::hasGuideEdge	(	int	edgeid,
		UT_Vector4 &	a,
		UT_Vector4 &	b
	)			const [virtual]

Reimplemented from GEO_Primitive.

virtual int GEO_PrimSphere::hasXsectPoint	(	int	pointid,
		UT_Vector4 &	p
	)			const [virtual]

Reimplemented from GEO_Primitive.

static GA_IntrinsicManager::Registrar GEO_PrimSphere::registerIntrinsics

(

GA_PrimitiveDefinition &

defn

)

[inline, static, protected]

All subclasses should call this method to register the sphere intrinsics.
