Bounds internal osg::Nodes in the scene, assists in view frustum culling, etc. Similar in function to BoundingBox, it's quicker for evaluating culling but generally will not cull as aggressively because it encloses a greater volume.

|
|
Returns the const center of the bounding sphere.
|
|
Returns the center of the bounding sphere.
|
|
Returns true if v is within the sphere.
|
|
Expands the sphere to encompass the given box. Repositions the sphere center to minimize the radius increase. |
|
Expands the sphere to encompass the given sphere. Repositions the sphere center to minimize the radius increase. If the sphere is uninitialized, set its center and radius to match sh. |
|
Expands the sphere to encompass the given point. Repositions the sphere center to minimize the radius increase. If the sphere is uninitialized, set its center to v and radius to zero. |
|
Expands the sphere to encompass the given box. Does not repositions the sphere center. |
|
Expands the sphere to encompass the given sphere. Does not repositions the sphere center. If the sphere is uninitialized, set its center and radius to match sh. |
|
Expands the sphere to encompass the given point. Does not reposition the sphere center. If the sphere is uninitialized, set its center to v and radius to zero. |
|
Clear the bounding sphere. Reset to default values. |

|
|
Returns the const radius of the bounding sphere.
|
|
Returns the radius of the bounding sphere.
|
|
Returns the squared length of the radius. Note, For performance reasons, the calling method is responsible for checking to make sure the sphere is valid. |
|
