  • Patent number: 12131503
    Abstract: Virtual creation and visualization of a physically based virtual material swatch includes identifying a capture device model to support for use in the generation of the virtual material swatch, determining camera response of the capture device model, determining lookup tables of linearly transformed cosines for a plurality of parameters of a shading model, identifying a sample physical material, and determining material description for the sample physical material. A system and method may also include scanning a user physical material, selecting one or more of material preset, geometry preset, environment preset, and camera preset, and creating a virtual material swatch for the user physical material based on the selections.

  • Patent number: 9177419
    Abstract: A simulation application models a surface of a fluid in motion. The simulation application selects a mesh point from a plurality of mesh points that is associated with the surface of the fluid. The simulation application retrieves a first texture element from a set of uv texture maps, and attaches a first displacement value to the mesh point based on the first texture element. The simulation application advects the first displacement value over a first duration represented by a first quantity of image frames such that the first displacement value remains attached to the mesh point as the plurality of mesh points moves in response to a motion of the fluid.
