Detailed Description

This funny bounding volume is an infinite plane that divides space into two regions: the part behind the normal, which is "inside" the bounding volume, and the part in front of the normal, which is "outside" the bounding volume.

Constructor & Destructor Documentation

BoundingPlane::BoundingPlane ( ) [inline]

Constructs an empty "plane" that has no intersections.

Member Function Documentation

const BoundingPlane * BoundingPlane::as_bounding_plane ( ) const [virtual]

Virtual downcast method.

Returns this object as a pointer of the indicated type, if it is in fact that type. Returns NULL if it is not that type.

Reimplemented from BoundingVolume.

Definition at line 81 of file boundingPlane.cxx.

int BoundingPlane::contains_box ( const BoundingBox * box ) const [protected, virtual]

Double-dispatch support: called by contains_other() when the type we're testing for intersection is known to be a box.

Reimplemented from BoundingVolume.

Definition at line 169 of file boundingPlane.cxx.

References BoundingBox::get_maxq(), BoundingBox::get_minq(), BoundingBox::get_point(), BoundingVolume::is_empty(), and BoundingVolume::is_infinite().

Referenced by BoundingBox::contains_plane().

int BoundingPlane::contains_hexahedron ( const BoundingHexahedron * hexahedron ) const [protected, virtual]

Double-dispatch support: called by contains_other() when the type we're testing for intersection is known to be a hexahedron.

Reimplemented from BoundingVolume.

Definition at line 243 of file boundingPlane.cxx.

References BoundingHexahedron::get_point(), BoundingVolume::is_empty(), and BoundingVolume::is_infinite().

int BoundingPlane::contains_line ( const BoundingLine * line ) const [protected, virtual]

Double-dispatch support: called by contains_other() when the type we're testing for intersection is known to be a line.

Reimplemented from BoundingVolume.

Definition at line 221 of file boundingPlane.cxx.

int BoundingPlane::contains_plane ( const BoundingPlane * plane ) const [protected, virtual]

Double-dispatch support: called by contains_other() when the type we're testing for intersection is known to be a plane.

Reimplemented from BoundingVolume.

Definition at line 231 of file boundingPlane.cxx.

int BoundingPlane::contains_sphere ( const BoundingSphere * sphere ) const [protected, virtual]

Double-dispatch support: called by contains_other() when the type we're testing for intersection is known to be a sphere.

Reimplemented from BoundingVolume.

Definition at line 142 of file boundingPlane.cxx.

References BoundingVolume::is_empty(), and BoundingVolume::is_infinite().

Referenced by BoundingSphere::contains_plane().

bool BoundingPlane::extend_by_plane ( const BoundingPlane * plane ) [protected, virtual]

Double-dispatch support: called by extend_other() when the type we're extending by is known to be a plane.

Reimplemented from BoundingVolume.

Definition at line 123 of file boundingPlane.cxx.

References BoundingVolume::is_empty(), and BoundingVolume::is_infinite().

static void BoundingPlane::init_type ( ) [inline, static]

This function is declared non-inline to work around a compiler bug in g++ 2.96.

Making it inline seems to cause problems in the optimizer.

Reimplemented from GeometricBoundingVolume.

Definition at line 73 of file boundingPlane.h.
