## Detailed Description

Implementation of a 3D bounding box.

This class provides an implementation of a bounding box. A bounding box describes a volume in space that bounds a piece of geometry. The box is defined by two points which describe the minimum and maximum corners of the box.

Examples:

  apiMeshShape.cpp, apiMeshShape.h, apiMeshShapeUI.cpp, curvedArrowsNode.cpp, D3DViewportRenderer.cpp, D3DViewportRenderer.h, footPrintManip.cpp, footPrintNode.cpp, hwColorPerVertexShader.cpp, hwPhongShader.cpp, OpenGLViewportRenderer.cpp, OpenGLViewportRenderer.h, quadricShape.cpp, simpleFluidEmitter.cpp, squareScaleManip.cpp, squareScaleManip.h, and swissArmyManip.cpp.
