void REveGeoShape::SetNSegments ( Int_t  s)

Set number of segments.

Definition at line 176 of file REveGeoShape.cxx.

◆ SetShape()

void REveGeoShape::SetShape ( TGeoShape s)

Set TGeoShape shown by this object.

The shape is owned by REveGeoShape but TGeoShape::fUniqueID is used for reference counting so you can pass the same shape to several EveGeoShapes.

If it if is taken from an existing TGeoManager, manually increase the fUniqueID before passing it to REveGeoShape.

◆ SubImportShapeExtract()

REveGeoShape * REveGeoShape::SubImportShapeExtract ( REveGeoShapeExtract gse,
REveElement parent 
)
staticprotected

Recursive version for importing a shape extract tree.

◆ WriteCoreJson()

Int_t REveGeoShape::WriteCoreJson ( nlohmann::json j,
Int_t  rnr_offset 
)
overridevirtual

Fill core part of JSON representation.

Reimplemented from ROOT::Experimental::REveElement.

◆ WriteExtract()

void REveGeoShape::WriteExtract ( const char *  name)

Write the shape tree as REveGeoShapeExtract to current directory.

FIXME: SL: no any write into gDirectory
