Return whether this Curve contains the given point. This is implemented as a numerical approximation. lementations can/should use the value test_threshold in common.h as a threshold value. Implements Curve. |
|
|
Returns a copy of this Object. The copy is an exact copy. Changes to the copy don't affect the original. Implements Curve. |

|
Returns the ObjectType representing the Ray type.
Reimplemented from AbstractLine. |

Returns the lowermost ObjectType that this object is an instantiation of. E.g. if you want to get a string containing the internal name of the type of an object, you can do:
tn = object.type().internalName() Implements Object. |
