All Known Implementing Classes:

ElementCircle

public interface ElementCircle
extends Element

Title: ElementSegment

Description: Draws a circle at its position with the given size. The default size is zero (which draws a point).

Because a circle is essentialy a 2D object, it doesn't behave completely as a 3D object. Thus, its center will be affected by transformations of the element, BUT ITS SIZE WON'T. Moreover, in 3D visualizations, the maximum of sizeX and sizeY is used for its horizontal size. In all other views, the corresponding size is used.
