Abstract: Particular embodiments described herein present a technique for mesh simplification. A computing system may receive a request to render an image of a virtual scene including a virtual object. The system may determine one or more positions of the virtual object relative to one or more of a foveal focus point or a lens, respectively. The system may determine a screen coverage size of the virtual object. The system may then determine a simplification level for the virtual object based on the determined position(s) and the screen coverage size of the virtual object. The system may generate a mesh representation of the virtual object based on the determined simplification level, where the number of polygons used in the mesh representation depends on the determined simplification level. The system may render the image of the virtual scene using at least the generated mesh representation of the virtual object.

Abstract: Techniques are disclosed for generating and using a conformal or UV mapping between an object's 3D representation (e.g., a polygonal mesh model) and a corresponding 2D representation (e.g., texture memory). More particularly, techniques disclosed herein generate a conformal mapping that allows the rapid identification of disparate locations in texture memory (e.g., those that span a seam) that are spatially similar at the corresponding 3D locations. The ability to perform 2D-to-3D-to-2D mappings quickly, grants the ability to filter across a conformal map's seams—an action that has previously been avoided due to its high computational cost.
