Detailed Description

An ObjectImp representing a conic.

A conic is a general second degree curve, and some beautiful theory has been developed about it. See a math book for more information. This class is in fact an abstract base class hiding the fact that a ConicImp can be constructed in two ways. If only its Cartesian equation is known, then you should use ConicImpCart, otherwise, you should use ConicImpPolar. If the other representation is needed, it will be calculated, but a cartesian representation is rarely needed, and not calculating saves some CPU cycles.

virtual

Implements ObjectImp.

bool ConicImp::equals ( const ObjectImp & rhs ) const

virtual

Returns true if this ObjectImp is equal to rhs.

This function checks whether rhs is of the same ObjectImp type, and whether it contains the same data as this ObjectImp.

It is used e.g. by the KigCommand stuff to see what the user has changed during a move.
