from panda3d.core import GeomCacheManager
- class GeomCacheManager
This is used to keep track of, and limit the size of, the cache of munged vertices, which would otherwise be distributed through all of the
GeomVertexDataobjects in the system.
The actual data in the cache is not stored here, but rather it is distributed among the various
GeomVertexDatasource objects. This allows the cache data to propagate through the multiprocess pipeline.
This structure actually caches any of a number of different types of pointers, and mixes them all up in the same LRU cache list. Some of them (such as GeomMunger) are reference-counted here in the cache; most are not.
Immediately empties all elements in the cache.
- getMaxSize() int
Returns the maximum number of entries in the cache for storing pre- processed data for rendering vertices. See
- setMaxSize(max_size: int)
Specifies the maximum number of entries in the cache for storing pre- processed data for rendering vertices. This limit is flexible, and may be temporarily exceeded if many different Geoms are pre-processed during the space of a single frame.
This is not a limit on the actual vertex data, which is what it is; it is also not a limit on the amount of memory used by the video driver or the system graphics interface, which Panda has no control over.
