Apple Applies for a New Patent: Perspective Correct Vector Graphics with Foveated Rendering
The US Patent & Trademark Office has published a new patent application from Apple, titled “Perspective Correct Vector Graphics with Foveated Rendering”. It relates to devices, systems and methods that implement certain rendering processes.
Here’s more about it.
Apple’s New Patent Application
Apple had introduced its much-awaited and most anticipated Vision Pro Headset at the brand’s WWDC23 event keynote held on the 5th of June, 2023, and the VP of Apple’s Technology Development Group, Mike Rockwell explained to the audience the key components used in Apple’s Vision Pro Headset. While talking about the visionOS, Rockwell also spoke about the Foveated Renderer used in the operating system.
For those of you who didn’t know, a Foveated Renderer uses a rendering technique that with the help of the eye tracker that is integrated with the virtual reality headset, reduces the workload of the device by focusing on the point where the eyes are pointed to and reducing the quality of the images in the peripheral vision. This is exactly how Apple’s Vision Pro Headset too works by delivering the maximum image quality to exactly where the user’s eyes are looking in each frame.
On the 15th of June 2023, Apple submitted a new patent application to the US Patent & Trademark Office which the company titled “Perspective Correct Vector Graphics with Foveated Rendering” and the patent application relates to the devices, systems, and methods which are used in the rendering processes that perform vector graphic rendering for its Vision Pro, iPhones, and other devices. In most parts of the application, it is revealed as of the company is speaking about a head-mounted device (HMD) that has an optical see-through or an opaque display in it.
As understood, the “Perspective Correct Vector Graphics with Foveated Rendering” that the company is trying to get a patent for, based on the gaze direction will be increasing the image quality of the focused region and will reduce the amount of computation and memory used in providing perspective correct rendering. An illustrative image has also been given below, depicting how the rendering process works.
