Nintendo filed 3 patents this month across 2 categories: Game Engines (2) and Hardware (1).
The Game Engines patents describe voxel-based systems for dynamically changing terrain and object appearances in response to environmental conditions like light exposure, as well as instantly modifying material properties and physics without altering underlying geometry. The Hardware patent covers a directional pad design that uses optical sensors and photo detectors instead of conventional rubber switches for input detection in game controllers.
Nintendo's 2 game engine patents both tackle the challenge of transforming virtual materials and terrain without the performance cost of rebuilding geometry. The first describes a voxel system that tracks materials at a per-voxel level and swaps them based on gameplay triggers such as light exposure from shadow buffers or geometric intersection tests, allowing terrain to visibly react to in-game events rather than relying on pre-designed states. The second takes a different approach by remapping material IDs to new rendering settings and physics properties, enabling instant transformations across entire virtual spaces that affect both how objects look and how they behave during gameplay, all without touching the underlying voxel data or regenerating meshes.
The single Hardware patent replaces the traditional rubber dome switches found in directional pads with an optical detection system that uses photo sensors to register input. This design maintains tactile feedback through a mechanical cushion and stopper arrangement while positioning the optical sensor on the outer side of the detection target, which allows for a smaller footprint and reduces the chance of incorrect input readings compared to conventional mechanical switch designs.
