const GEO_MetaPrim* GEO_PrimMetaBall::castToMetaPrim ( ) const

overridevirtual

GEO_Primitive* GEO_PrimMetaBall::copy ( int preserve_shared_pts = 0 ) const

Reimplemented from GEO_Primitive.

void GEO_PrimMetaBall::copyPrimitive ( const GEO_Primitive * src )

overridevirtual

Implements GEO_Primitive.

void GEO_PrimMetaBall::copySubclassData ( const GA_Primitive * source )

overridevirtual

Copy all subclass data from source to this.

The vertex lists of source and this must already be equivalent in some manner, though possibly referring to different vertices.

If some subclass data is dependent on the vertex list contents, (such as GEO_PrimPolySoup::myPolygonVertexList), it should be mapped based on the correspondence between the two. GEO_PrimPolySoup is currently the only primitive type with this sort of dependence, so it's probably best not to add more.

NOTE: This must be safe to call on different primitives in parallel at the same time.

void GEO_PrimMetaBall::getBBox ( UT_BoundingBox & bbox ) const

overridevirtual

Implements GEO_MetaPrim.

bool GEO_PrimMetaBall::getBBox ( UT_BoundingBox * bbox ) const

inlineoverridevirtual

Compute the bounding box of the primitive. Return 0 if unable to compute bounds (1 on successful computation). This function should always initialize bbox, even if returning false, in which case, the bbox->isValid() may be false, representing an empty bounding box. This function should also not use any initial value of bbox, so it does not need to be initialized beforehand.

Implements GEO_Quadric.

const GA_PrimitiveJSON* GEO_PrimMetaBall::getJSON ( ) const

overridevirtual

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).
