Detailed Description

This is a special class object, similar to a TextureContext, that holds all the information returned by a particular GSG to cache the rendering information associated with one or more Geoms.

This is similar to, but different from, a GeomNode context, which is associated with the containing GeomNode class; a GSG might prefer to associate data with either the Geom or the GeomNode or both.

This allows the GSG to precompute some information necessary for drawing the Geoms as quickly as possible and reuse that information across multiple frames. Typically, only static Geoms (e.g. nonindexed) will be assigned GeomContexts.

virtual TypeHandle GeomContext::force_init_type void   )  [inline, virtual]
 

Reimplemented from SavedContext.

Definition at line 85 of file geomContext.h.

TypeHandle GeomContext::get_class_type void   )  [inline, static]
 

Reimplemented from SavedContext.

Definition at line 74 of file geomContext.h.

virtual TypeHandle GeomContext::get_type void   )  const [inline, virtual]
 

Reimplemented from SavedContext.

Definition at line 82 of file geomContext.h.

int TypedObject::get_type_index  )  const [inline, inherited]
 

Returns the internal index number associated with this object's TypeHandle, a unique number for each different type.

This is equivalent to get_type().get_index().

void GeomContext::init_type void   )  [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 SavedContext.

Definition at line 77 of file geomContext.h.

bool TypedObject::is_exact_type TypeHandle  handle  )  const [inline, inherited]
 

Returns true if the current object is the indicated type exactly.

Definition at line 101 of file typedObject.I.

bool TypedObject::is_of_type TypeHandle  handle  )  const [inline, inherited]
 

Returns true if the current object is or derives from the indicated type.
