This month's Graphics & Rendering category includes 4 granted patents across 4 companies: EA (1), Activision Blizzard (1), Nintendo (1), and Sony (1).
Activision Blizzard patented a system that dynamically budgets and scales per-light shadow map resolution while filtering softened shadows to maintain performance, and EA patented a neural network approach that predicts clothing mesh and normal maps from character joint rotations as a replacement for physics-based cloth simulation. Nintendo patented a vertex shader technique that fakes depth in orthographic 2D games by scaling objects without disrupting collision detection, while Sony patented a dedicated controller button that smoothly fades between graphics quality modes in real-time, giving players direct access to visual fidelity settings without navigating menus.
Activision Blizzard received 1 patent covering how shadow rendering is managed at runtime. Rather than setting shadow map resolutions in advance based on expected scene configurations, the system continuously monitors a memory budget and adjusts resolution per light source based on factors like light size and camera distance. It also converts percentage closer filtering values into a curved attenuation profile, which produces softer shadows while keeping the overall rendering load within defined limits.
EA received 1 patent for a method of handling clothing deformation without relying on physics simulation. A trained neural network takes in character joint rotations and produces compressed representations of both the clothing mesh and its normal maps in a single pass, with no dependence on what the previous frame looked like. The training data comes from running physics simulations over posed skeletons and baking those results into lower-resolution meshes paired with normal maps, effectively front-loading the computational cost rather than carrying it into real-time rendering.
Nintendo's 1 patent addresses a visual limitation in orthographic 2D games by applying size scaling exclusively at the vertex shader stage during rendering. Because the enlargement or reduction happens only in the graphics pipeline and never touches the underlying game logic, collision detection and gameplay calculations remain unaffected. Players perceive objects as closer or farther away based on their apparent size, while the game engine continues operating as though no depth displacement exists at all.
Sony received 1 patent describing a controller-level mechanism for switching between graphics quality modes. A dedicated physical button triggers a smooth interpolated fade from one rendering quality setting to another, avoiding the abrupt visual pop that would come from an instant switch. Unlike automated Dynamic Resolution Scaling tied to frame rate metrics, this approach puts direct, tactile control in the player's hands, with no menu navigation required.
