## Detailed Description

Allows the rendering of a wireframe bounding box.

This class builds a wireframe renderable from a given aabb. A pointer to this class can be added to a render queue to display the bounding box of an object.

## Member Function Documentation

## setupBoundingBox()

void Ogre::WireBoundingBox::setupBoundingBox | ( | const AxisAlignedBox & | aabb | ) |

Builds the wireframe line list.

Parameters

  aabb | bounding box to build a wireframe from.

## getSquaredViewDepth()

Real Ogre::WireBoundingBox::getSquaredViewDepth | ( | const Camera * | cam | ) | const

override virtual

Returns the squared distance between the camera and this renderable.

Implements Ogre::Renderable.

## getBoundingRadius()

Real Ogre::WireBoundingBox::getBoundingRadius | ( | void |  | ) | const

inline override virtual

Retrieves the radius of the origin-centered bounding sphere for this object.

Implements Ogre::MovableObject.
