Member Enumeration Documentation

enum Shape::ShapeType [inherited]

This is the list of identifiers used for shapes. Identifiers are mean to be explicit ...

  • union_ is used instead of 'union' because 'union' is a C++ keyword.
  • not_ is used instead of 'not' because 'not' is a C++ keyword.
Enumerator:
sphere 
cylinder 
cone 
cube 
plane 
torus 
union_ 
difference 
intersection 
not_ 
infiniteCylinder 
infiniteCone
