Mobile Game Event Replay Using Reusable Rendering Resources

The patent segments game resources into two categories: reusable resources (models, textures, materials, animations) and non-reusable resources (dynamic data). By separating resource management into these segments, the system can efficiently handle replay rendering without duplicating entire resource sets, thereby reducing memory overhead while maintaining replay functionality on mobile devices.

The patent creates a virtual copy of the game world for replay purposes by instantiating a replay camera and replay renderer that operate independently from the main game renderer. This virtual copy allows historical game events to be rendered without duplicating physical game objects, reducing CPU and memory overhead while enabling real-time replay on mobile devices.

The patent performs preliminary actions by pre-processing and storing game resources during the original game execution. The reusable game resources are prepared in advance and stored for later retrieval during replay, eliminating the need to recreate them during historical event rendering. This preliminary preparation ensures rendering accuracy while avoiding redundant operations during replay.

The patent implements a resource recovery mechanism where game resources are discarded after the original game execution completes but retained in a reusable pool. During replay, these recovered resources are reused rather than recreated, maintaining rendering accuracy while significantly reducing the computational overhead of redundant resource creation operations.
