Hair design and rendering

A non-transitory computer-readable medium with instructions stored thereon that, responsive to execution by a processing device, cause the processing device to perform operations comprising:

• receiving, at a user device that participates in a virtual experience, a hair model for a 3D object, wherein the hair model includes a plurality of curves, hair geometry metadata associated with one or more curves of the plurality of curves, and hair simulation metadata;
• generating, at the user device, hair geometry for the 3D object based on the hair model, the hair geometry metadata, and a type of the user device;
• simulating, at the user device, hair for the 3D object based on the hair geometry, the hair simulation metadata, and one or more physics parameters of the virtual experience;
• and
• rendering the 3D object with the simulated hair on the user device.

A system comprising:

• a memory with instructions stored thereon;
• and
• a processing device, coupled to the memory, the processing device configured to access the memory and execute the instructions, wherein the instructions cause the processing device to perform operations comprising:
• receiving, at a user device that participates in a virtual experience, a hair model for a 3D object, wherein the hair model includes a plurality of curves, hair geometry metadata associated with one or more curves of the plurality of curves, and hair simulation metadata;
• generating, at the user device, hair geometry for the 3D object based on the hair model, the hair geometry metadata, and a type of the user device;
• simulating, at the user device, hair for the 3D object based on the hair geometry, the hair simulation metadata, and one or more physics parameters of the virtual experience;
• and
• rendering the 3D object with the simulated hair on the user device.
