[inline, static, protected]

We explicitly do not include the mask from the GEO_PrimSphere base.

(

)

const [virtual]

Reimplemented from GEO_Primitive.

virtual GEO_MetaPrim* GEO_PrimMetaBall::castToMetaPrim

(

)

[virtual]

Reimplemented from GEO_Primitive.

const [virtual]

virtual void GEO_PrimMetaBall::copyOffsetPrimitive	(	const GEO_Primitive *	src,

	)			[protected, virtual]

Reimplemented from GEO_Quadric.

virtual void GEO_PrimMetaBall::copyPrimitive	(	const GEO_Primitive *	src,

	)			[virtual]

Reimplemented from GEO_Quadric.

virtual void GEO_PrimMetaBall::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.

virtual const GA_PrimitiveJSON* GEO_PrimMetaBall::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).

Reimplemented from GEO_PrimSphere.

Report approximate memory usage.

Reimplemented from GEO_PrimSphere.

virtual int GEO_PrimMetaBall::localGetIntrinsicF	(	const GA_IntrinsicEval &	eval,

As this is a multiple-base class off GEO_MetaPrim, all intrinsic methods need to be defined (since the meta primitive intrinsics need to be considered).

Further sub-classes may simply override the specific methods for their attributes.

static GA_IntrinsicManager::Registrar GEO_PrimMetaBall::registerIntrinsics

(

)

[static, protected]

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

GA_AttributeIntrinsic

Reimplemented from GEO_PrimSphere.

virtual bool GEO_PrimMetaBall::savePrivateH9	(	ostream &	os,
		bool	binary
	)			const [protected, virtual]

Reimplemented from GEO_Quadric.

virtual void GEO_PrimMetaBall::stashed	(	int	onoff,
		GA_Offset	offset = GA_INVALID_OFFSET
	)			[virtual]

Stash (deactivate) or unstash (reactivate) the primitive.

Stashing a primitive will set its offset to that specified, typically GA_INVALID_OFFSET. Primitives are only stashed as part of clearing a detail, so there is no need to explicitly deallocate vertices. It is safe to delete a stashed primitive.

Unstashing a primitive will re-register that primitive with its parent detail at the specified offset (or a new offset if GA_INVALID_OFFSET).

Reimplemented from GEO_Quadric.
