VisualizationFoundation CAT2DBoundingSphere
Usage: you must use this class as is. You should never derive it.
public class CAT2DBoundingSphere
Class to manage bounding surface of 2D elements.
Role:This class is used to manage the space used by a 2D
element. This information is used at the rendering time to know if a given
element is visible on the screen and needs to be drawn or not.
2DBoundingSpheres are Circles.
For performance issues BoundingSpheres need to be as close to the object they are linked
to as possible. Idealy they represent the smallest circle containing the object.
You can add 2 2DBoundingSpheres using the += operator inherited from boundingElements.

Copy constructor
o CAT2DBoundingSphere
| public CAT2DBoundingSphere( | const | center, |
| const | radius, |
| const | radius_mm | = 0.f) |
-
Constructs a 2DBoundingSphere with a given center, radius and radius in mm.
- Parameters:
-
- center
- The center of the boundingSphere.
- radius
- The radius of the boundingSphere in model unit.
- radius_mm
- This is used for elements with fixed size on the screen on which
zoom has no effect. Default is 0.
