Detailed Description

This functions similarly to a LightAttrib.

It indicates the set of clipping planes that modify the geometry at this level and below. A ClipPlaneAttrib can either add planes or remove planes from the total set of clipping planes in effect.

int ClipPlaneAttrib::complete_pointers ( TypedWritable **  p_list,
BamReader manager 
)
virtual

Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().

Returns the number of pointers processed.

Reimplemented from TypedWritable.

int ClipPlaneAttrib::get_num_off_planes ( ) const
inline

Returns the number of planes that are disabled by the attribute.

int ClipPlaneAttrib::get_num_on_planes ( ) const

Returns the number of planes that are enabled by the attribute.

Referenced by PGItem::activate_region(), GraphicsStateGuardian::fetch_specified_part(), get_num_planes(), and write_datagram().

int ClipPlaneAttrib::get_num_planes ( ) const

Returns the number of planes listed in the attribute.

This method is now deprecated. ClipPlaneAttribs nowadays have a separate list of on_planes and off_planes, so this method doesn't make sense. Query the lists independently.

NodePath ClipPlaneAttrib::get_off_plane ( int  n) const

Returns the nth plane disabled by the attribute, sorted in arbitrary (pointer) order.

Referenced by PGItem::activate_region(), GraphicsStateGuardian::fetch_specified_part(), and get_plane().

ClipPlaneAttrib::Operation ClipPlaneAttrib::get_operation ( ) const

Returns the basic operation type of the ClipPlaneAttrib.

If this is O_set, the planes listed here completely replace any planes that were already on. If this is O_add, the planes here are added to the set of of planes that were already on, and if O_remove, the planes here are removed from the set of planes that were on.

This method is now deprecated. ClipPlaneAttribs nowadays have a separate list of on_planes and off_planes, so this method doesn't make sense. Query the lists independently.

PlaneNode * ClipPlaneAttrib::get_plane ( int  n) const

Returns the nth plane listed in the attribute.

This method is now deprecated. ClipPlaneAttribs nowadays have a separate list of on_planes and off_planes, so this method doesn't make sense. Query the lists independently.

bool ClipPlaneAttrib::has_all_off ( ) const

Returns true if this attrib disables all planes (although it may also enable some).

bool ClipPlaneAttrib::is_identity ( ) const

Returns true if this is an identity attrib: it does not change the set of planes in use.

References ordered_vector< Key, Compare, Vector >::empty().

void ClipPlaneAttrib::register_with_read_factory ( )
static

Tells the BamReader how to create objects of type ClipPlaneAttrib.

Definition at line 942 of file clipPlaneAttrib.cxx.

References BamReader::get_factory(), and Factory< Type >::register_factory().

bool ClipPlaneAttrib::require_fully_complete ( ) const
virtual

Some objects require all of their nested pointers to have been completed before the objects themselves can be completed.

If this is the case, override this method to return true, and be careful with circular references (which would make the object unreadable from a bam file).

Reimplemented from TypedWritable.
