Activision Blizzard received 1 granted patent in Graphics.
The patent addresses shadow rendering optimization in video games by dynamically allocating and scaling resolution for individual light source shadow maps within each frame. The technology applies filtered softening to the shadows while maintaining consistent performance across different gaming Platformss.
A single Graphics patent tackles the challenge of rendering realistic shadows without overwhelming system resources. The technology allocates a runtime memory budget for shadow maps, then adjusts the resolution for each individual light source based on factors like the light's size and its distance from the camera. This approach means shadow quality adapts automatically during gameplay rather than relying on fixed settings that assume where players will be looking. The system also applies a transformation to filtering values that creates smoother shadow edges while reducing visual artifacts, connecting the memory budget directly to image quality improvements.
