Description
Nintendo continues to push the boundaries of visual technology with its recently approved US Patent US 2025/0090952, which outlines an innovative method for rendering video game graphics that blend three-dimensional and two-dimensional visual styles.
The patent, granted on March 20, 2025, under the title 'Non-Transitory Computer-Readable Storage Medium Having Game Program Stored Therein, Game System, Game Processing Method, and Game Apparatus', spotlights Nintendo’s ongoing commitment to technical experimentation for its current and future game libraries on platforms like the Nintendo Switch and beyond.
At its core, the patent describes a software-based approach that allows a 3D virtual space to be depicted in a way that visually feels two-dimensional.
This is achieved through sophisticated manipulation of visual elements, particularly in the rendering of shadows.
The technique employs Screen Space Ambient Occlusion (SSAO) to cast block-like shadows on background objects, deliberately minimizing the distance between the character and its corresponding shadow.
This creates a "flattened" aesthetic, mimicking the depth and perspective of 2D art while retaining the advantages of 3D game environments.
The official documentation provides further detail, noting that the rendering system can "deform and display a predetermined object so that its normal vector aligns more closely with the direction of the virtual camera." In practical terms, this adjusts how characters and objects interact with lighting, allowing them to be rendered in a visually 2D manner without sacrificing the depth cues and dynamic elements afforded by 3D engines.
Although accompanying diagrams are sparse on specifics about where this technology might be implemented, some industry observers have drawn comparisons to Square Enix’s celebrated HD-2D visual style used in titles like 'Octopath Traveler.' Social media voices, including influencer Mike Odyssey, have even speculated about the potential to use the system for future remakes of beloved Nintendo games such as 'The Legend of Zelda: A Link to the Past.'
However, a closer look at prior patent filings reveals that Nintendo has previously explored similar visual techniques, with related applications dating back to 2022 and 2023.
These earlier incarnations include diagrams evocative of established Nintendo franchises, particularly the Paper Mario series and mobile titles like Mario Kart Tour, both known for their interplay between 2D and 3D presentation.
Nintendo enthusiasts hoping for direct connections to upcoming remakes or new game styles should temper expectations for now.
While the patented technology demonstrates Nintendo’s interest in novel graphic rendering techniques, there are no official indications of imminent deployment in first-party titles.
As Nintendo Wire reported, such patents highlight ongoing internal research rather than guaranteed product features.
With Nintendo Switch and its future successor commonly referred to as "Switch 2" on the horizon, this patented visual tech underscores the company's drive to evolve its game presentation.
As the gaming industry awaits further announcements from Nintendo Direct events and potential software showcases, all eyes will be on how these innovations may eventually materialize in future titles.
