Description

Data strategy for meshes that are handled inside a cache system. It collects usage data for the meshes and handles the cache movement between CPU and GPU memory.

enum missing_mode_t
Enumerator   Description
Enumerator   Description
NO_WAIT_DO_NOTHING   Do not wait until loading has been finished, and do nothing else.
NO_WAIT_DISPLAY_COLORED_BOX   Do not wait until loading has been finished, and display a colored bounding box.
NO_WAIT_DISPLAY_DEPTH_BOX   Do not wait until loading has been finished, and write a bounding box to the depth buffer.
WAIT_DISPLAY   Wait until loading has been finished, and display the cache object afterwards.

Mode for drawing a cache object that is currently not in memory.
