Abstract: Embodiments are configured to render 3D models using an importance sampling method. First, embodiments obtain a 3D model including a plurality of density values corresponding to a plurality of locations in a 3D space, respectively. Embodiments then sample the color information from within a random subset of the plurality of locations using a probability distribution based on the plurality of density values. Embodiments have a higher probability to sample each location within the random subset of locations if the location has a higher density probability. Embodiments then an image depicting a view of the 3D model based on the sampling within the random subset of the plurality of locations.

Abstract: A system generates, based on a displacement bounds data structure and a triangle mesh modeling a surface of a 3D virtual object within a 3D virtual scene, a displaced triangle mesh including one or more displaced surface bounding prisms, each of the one or more displaced surface bounding prisms displaced from a respective base triangle of a plurality of base triangles of the triangle mesh structure based on displacement bounds defined in a displacement bounds data structure for an area of a 2D texture space corresponding to a location of the respective base triangle defined by the 3D virtual scene. The system performs, using the displaced triangle mesh structure, a ray tracing process for a ray associated with a pixel of a 2D image of the virtual scene including determining, responsive to determining the ray intersects the particular displaced surface bounding prism, a location of an intersection of the ray.
