FUNCTION SPECIFICATION
#include <Performer/pf.h>
pfSolid * pfNewSolid(void *arena);
pfType * pfGetSolidClassType(void);
void pfSolidAddSurface(pfSolid *solid, pfParaSurface *sur);
pfParaSurface * pfGetSolidSurface(pfSolid *solid, int i);
int pfGetSolidSurfaceCount(pfSolid *solid);
void pfSolidSolidId(pfSolid *solid, int solidId);
void pfGetSolidSolidId(pfSolid *solid);
PARENT CLASS FUNCTIONS
The OpenGL Performer class pfSolid is derived from the parent class
pfObject, so each of these member functions of class pfObject are also
directly usable with objects of class pfSolid. Casting an object of
class pfSolid to an object of class pfObject is taken care of
automatically. This is also true for casts to objects of ancestor
classes of class pfObject.
void pfUserDataSlot(pfObject *obj, int slot, void *data);
void pfUserData(pfObject *obj, void *data);
void* pfGetUserDataSlot(pfObject *obj, int slot);
void* pfGetUserData(pfObject *obj);
int pfGetNumUserData(pfObject *obj);
int pfGetNamedUserDataSlot(const char *name);
const char* pfGetUserDataSlotName(int slot);
int pfGetNumNamedUserDataSlots(void);
int pfDeleteGLHandle(pfObject *obj);
Since the class pfObject is itself derived from the parent class
pfMemory, objects of class pfSolid can also be used with these functions
designed for objects of class pfMemory.

DESCRIPTION
An pfSolid is a set of connected surfaces. The surfaces need not form a
closed surface, that is, the boundary of a solid, but may define a
surface with edges. You can find solids based on topology information
(See pfTopo::buildSolids).
pfNewSolid creates and returns a handle to a pfSolid. arena specifies a
malloc arena out of which the pfSolid is allocated or NULL for allocation
off the process heap. pfSolids can be deleted with pfDelete.
pfGetSolidClassType returns the pfType* for the class pfSolid. the
pfType* returned by pfGetSolidClassType is the same as the pfType*
returned by invoking pfGetType on any instance of class pfSolid. Because
OpenGL Performer allows subclassing of built-in types, when decisions are
made based on the type of an object, it is usually better to use
pfIsOfType to test if an object is of a type derived from a Performer
type rather than to test for strict equality of the pfType*'s.
pfSolidAddSurface add a surface to the solid.
pfGetSolidSurfaceCount returns the number of surfaces in this solid.
pfSolidSolidI sets the index of the solid in the solid list of the
topology.
pfGetSolidSolidId returns the index of the solid in the solid list of the
topology.
