RectangleBoundingBox Class

The RectangleBoundingBox class represents a bounding box for an object, i.e. the surrounding box of the object. The bounding box contains the calculated corner points of the box. The rectangle bounding box is inherited from the axis-aligned bounding box. The AABB also contains methods for getting the center point of the box.

[SerializableAttribute]
public sealed class RectangleBoundingBox : AABB, 
	IIsEqual

<SerializableAttribute>
Public NotInheritable Class RectangleBoundingBox
	Inherits AABB
	Implements IIsEqual

The RectangleBoundingBox type exposes the following members.

Properties

	Name	Description
	AngleToAxis	The angle of the bounding box in relation to the axis (the coordinate system's X-plane).
	Height	The height of the bounding box.
	LowerLeft	The lower left corner point of the bounding box.
	LowerRight	The lower right corner point of the bounding box.
	MaxPoint	The maximum point of the axis-aligned 3d bounding box. (Inherited from AABB.)
	MinPoint	The minimum point of the axis-aligned 3d bounding box. (Inherited from AABB.)
	UpperLeft	The upper left corner point of the bounding box.
	UpperRight	The upper right corner point of the bounding box.
	Width	The width of the bounding box.

Methods

	Name	Description
	Collide	Checks if the current axis-aligned 3d bounding box collides with another given axis-aligned 3d bounding box. Both axis-aligned 3d bounding boxes need to be in the same coordinate system or in the same workplane, so that they are defined using the same axes. (Inherited from AABB.)
	CreateRectangleBoundingBox	Creates a new RectangleBoundingBox with the given values.
	GetCenterPoint	Returns the geometric center point of the current axis-aligned 3d bounding box. (Inherited from AABB.)
	GetCornerPoints	Returns all corner points of the current axis-aligned 3d bounding box. (Inherited from AABB.)
	IsEqual	Compares the current object with an object of the same type.
	IsInside(LineSegment)	Checks if the given line segment is inside the current axis-aligned 3d bounding box. (Inherited from AABB.)
	IsInside(Point)	Checks if the given point is inside the current axis-aligned 3d bounding box. (Inherited from AABB.)
	ToString	Returns the rectangle bounding box values as a string. (Overrides ObjectToString.)

Examples

The following example is about how to draw a polygon around an object's bounding box:

Copy

using Tekla.Structures.Drawing;

public class Example
{
       static bool DrawBB(ViewBase DrawView, RectangleBoundingBox boundingBox, DrawingColors Color)
       {
           PointList points = new PointList();
           points.Add(boundingBox.LowerLeft);
           points.Add(boundingBox.UpperLeft);
           points.Add(boundingBox.UpperRight);
           points.Add(boundingBox.LowerRight);
           Polygon MyPolygon = new Polygon(DrawView, points);
           MyPolygon.Attributes.Line.Color = Color;
           MyPolygon.Insert();

           return true;
       }
}
