from panda3d.core import GraphicsStateGuardianBase
- class GraphicsStateGuardianBase¶
This is a base class for the
GraphicsStateGuardianclass, which is itself a base class for the various GSG’s for different platforms. This class contains all the function prototypes to support the double-dispatch of GSG to geoms, transitions, etc. It lives in a separate class in its own package so we can avoid circular build dependency problems.
GraphicsStateGuardiansare not actually writable to bam files, of course, but they may be passed as event parameters, so they inherit from
TypedReferenceCountfor that convenience.
- static getDefaultGsg() GraphicsStateGuardianBase ¶
Returns a pointer to the “default” GSG. This is typically the first GSG created in an application; in a single-window application, it will be the only GSG. This GSG is used to determine default optimization choices for loaded geometry.
The return value may be NULL if a GSG has not been created.
- static getGsg(n: int) GraphicsStateGuardianBase ¶
Returns the nth GSG in the universe. GSG’s automatically add themselves and remove themselves from this list as they are created and destroyed.
