virtual void write_datagram(BamWriter *manager, Datagram &dg)
Writes the contents of this object to the datagram for shipping out to a Bam file.
This is the fundamental interface for writing binary objects to a Bam file, to be extracted later by ...
void write_pointer(Datagram &packet, const TypedWritable *dest)
The interface for writing a pointer to another object to a Bam file.
This is the base class for a number of render attributes (other than transform) that may be set on sc...
virtual int complete_pointers(TypedWritable **plist, BamReader *manager)
Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().
Applies a Fog to the geometry at and below this node.
bool is_off() const
Returns true if the FogAttrib is an 'off' FogAttrib, indicating that it should disable fog.
static WritableFactory * get_factory()
Returns the global WritableFactory for generating TypedWritable objects.
static size_t add_hash(size_t start, const void *key)
Adds the indicated key into a running hash.
static void register_with_read_factory()
Tells the BamReader how to create objects of type FogAttrib.
virtual void write_datagram(BamWriter *manager, Datagram &dg)
