Public Attributes | |
Vec3 | _min |
Minimum extent. | |
Vec3 | _max |
Maximum extent. |
Bounds leaf objects in a scene such as osg::Drawable objects. Used for frustum culling etc.
|
Creates an uninitialized bounding box.
|
|
Creates a bounding box initialized to the given extents.
|
|
Creates a bounding box initialized to the given extents.
|
|
Calculates and returns the bounding box center.
|
|
Returns true if this bounding box contains the specified coordinate.
|
|
Returns a specific corner of the bounding box. pos specifies the corner as a number between 0 and 7. Each bit selects an axis, X, Y, or Z from least- to most-significant. Unset bits select the minimum value for that axis, and set bits select the maximum. |
|
Expands this bounding box to include the given sphere. If this box is uninitialized, set it to include sh. |
|
Expands this bounding box to include the given bounding box. If this box is uninitialized, set it equal to bb. |
|
Expands the bounding box to include the given coordinate. If the box is uninitialized, set its min and max extents to Vec3(x,y,z). |
|
Expands the bounding box to include the given coordinate. If the box is uninitialized, set its min and max extents to v. |
|
Clear the bounding box. Erases existing minimum and maximum extents. |
|
Returns the intesection of this bounding box and the specified bounding box.
|
|
Return true if this bounding box intersects the specified bounding box.
|
|
Calculates and returns the bounding box radius.
|
|
Calculates and returns the squared length of the bounding box radius. |
|
Sets the bounding box extents.
|
|
Sets the bounding box extents.
