Apple wants its Vision Pro Personas to have more realistic hair

FIGS. 2B-2C are examples of projecting a plurality of hair strands to a hair mesh in order to generate a more realistic hair texture.

Apple wants its Apple Vision Pro Personas to have more realistic hair as evidenced by a newly granted patent (number US 11983810 B1) for “Projection Based Hair Rendering.”

About the patent 

Vision Pro users can create a digital Persona that allows others to see them while they’re wearing the headset. Apple says it’s “a dynamic, natural representation of your face and hand movements while you’re using FaceTime. However, the feature has been frequently criticized for offering “creepy” Personas. Apple wants to change this.

In the patent Apple notes that previously available hair rendering methods have various shortcomings. For example, rendering based on hair card data is computationally expensive due to a relatively large corresponding hair texture size and complexities associated with translating the hair texture. As another example, rendering based on hair strand data is associated with aliasing and strand deformation issues. Apple wants the Personas on the Vision Pro to overcome such limitations. 

Summary of the patent

Here’s Apple’s abstract of the patent: “A method is performed at an electronic device with one or more processors and a non-transitory memory. The method includes obtaining hair curve data that represents a plurality of hair strands. Each of the plurality of hair strands includes a respective plurality of hair points. The method includes projecting the plurality of hair strands to a hair mesh that is associated with a virtual agent. 

“The method includes rendering a first subset of the plurality of hair strands in order to generate a hair texture based on a corresponding portion of the projection. The method includes rendering the hair texture in association with the virtual agent in order to generate a display render. In some implementations, the method includes changing the number of hair strands rendered during a particular rendering cycle, enabling dynamic generation of hair textures across rendering cycles.”
