Activision Blizzard holds 3 granted patents spanning 2 categories: Graphics (1) and Game Engines (2).
The Graphics patent covers automated Level of Detail mesh generation using point clouds and virtual imaging probes to optimize rendering performance across different Hardware. The Game Engines patents describe an automated testing infrastructure that runs multiple game builds across diverse Hardware configurations to capture performance data, as well as a system for smoothly animating first-person weapon views around corners to eliminate visual discontinuities during tactical movements.
The Graphics patent addresses a longstanding challenge in game development by automating the creation of Level of Detail meshes, which allow games to adjust visual complexity based on how far objects appear from the player. The system positions virtual imaging probes in spherical or hemispherical patterns around game environments, then uses GPU acceleration to analyze these viewpoints and determine which geometric detail can be safely removed at various distances. This approach reduces the need for artists to manually create multiple versions of each asset while generating simpler geometry than traditional grid-based methods.
Two game engine patents tackle distinct aspects of development workflow and player experience. The testing infrastructure runs multiple builds of a game simultaneously across different Hardware setups, scripting avatar movement along predetermined paths through open-world environments to collect consistent performance metrics from each configuration. The weapon animation system eliminates the jarring visual snap that occurs when players peek around corners in first-person shooters by implementing an algorithm that scores nearby edges based on geometric relationships to the player's view direction and position, then smoothly interpolates weapon rotation and position using different parameters depending on whether the player aims down sights or fires from the hip.
