class GraphicsStateGuardian

Detailed Description

A table of objects that are saved within the graphics context for reference by handle later.

Generally, this represents things like OpenGL texture objects or display lists (or their equivalent on other platforms).

This object simply records the pointers to the context objects created by the individual GSG's; these context objects will contain enough information to reference or release the actual object stored within the graphics context.

These tables may potentially be shared between related graphics contexts, hence their storage here in a separate object rather than as a part of the GraphicsStateGuardian.

void PreparedGraphicsObjects::begin_frame ( GraphicsStateGuardianBase *  gsg,
Thread *  current_thread 
)

This is called by the GraphicsStateGuardian to indicate that it is about to begin processing of the frame.

Any texture contexts that were previously passed to release_texture() are actually passed to the GSG to be freed at this point; textures that were previously passed to prepare_texture are actually loaded.

bool PreparedGraphicsObjects::dequeue_geom ( Geom *  geom)

Removes a geom from the queued list of geoms to be prepared.

Normally it is not necessary to call this, unless you change your mind about preparing it at the last minute, since the geom will automatically be dequeued and prepared at the next frame.

The return value is true if the geom is successfully dequeued, false if it had not been queued.

Sets an artificial cap on graphics memory that will be imposed on this GSG.

This limits the total amount of graphics memory, including texture memory and vertex buffer memory, that will be consumed by the GSG, regardless of whether the hardware claims to provide more graphics memory than this. It is useful to put a ceiling on graphics memory consumed, since some drivers seem to allow the application to consume more memory than the hardware can realistically support.
