Detailed Description
A bounding volume that forms a volume of zero size and location.
When applied to a node, this volume will never intersect any other bounding volumes, and will never be considered inside the camera's frustum.
Member Function Documentation
| - (BOOL) doesIntersect: | (CC3BoundingVolume *) | aBoundingVolume |
Returns whether this bounding volume intersects the specfied other bounding volume.
This implementation always returns NO.
Implements CC3BoundingVolume.
| - (BOOL) doesIntersectConvexHullOf: | (GLuint) | numOtherPlanes | |
| planes: | (CC3Plane *) | otherPlanes | |
| from: | (CC3BoundingVolume *) | otherBoundingVolume | |
Returns whether a convex hull composed of the specified global planes intersects this bounding volume.
The planes may be the face planes of a mesh, or they may be the sides of an oriented bounding box (OBB), or frustum, etc.
This implementation always returns NO.
Implements CC3BoundingVolume.
| - (BOOL) doesIntersectLocation: | (CC3Vector) | aLocation |
Returns whether the specified global location intersects (is inside) this bounding volume.
This implementation always returns NO.
Implements CC3BoundingVolume.
| - (BOOL) doesIntersectRay: | (CC3Ray) | aRay |
Returns whether the specified global-coordinate ray intersects this bounding volume.
This implementation always returns NO.
The shouldIgnoreRayIntersection property has no effect on this implementation.
Implements CC3BoundingVolume.
| - (BOOL) doesIntersectSphere: | (CC3Sphere) | aSphere | |
| from: | (CC3BoundingVolume *) | otherBoundingVolume | |
Returns whether the specified global-coordinate sphere intersects this bounding volume.
This implementation always returns NO.
Implements CC3BoundingVolume.
| - (BOOL) isInFrontOfPlane: | (CC3Plane) | aPlane |
Returns whether this bounding volume lies completely outside the specified normalized global coordinate plane.
This implementation always returns YES.
Implements CC3BoundingVolume.
Property Documentation
- (BOOL) shouldDraw [read, write, assign] |
Indicates that this bounding volume should draw itself over the node.
The null bounding volume will never be drawn. This property will always return NO, and setting this property will have no effect.
Implements CC3NodeBoundingVolume.
