Abstract: Aspects and features of the present disclosure provide a direct ray tracing operator with a low memory footprint for surfaces enriched with displacement maps. A graphics editing application can be used to manipulate displayed representations of a 3D object that include surfaces with displacement textures. The application creates an independent map of a displaced surface. The application ray-traces bounding volumes on the fly and uses the intersection of a query ray with a bounding volume to produce rendering information for a displaced surface. The rendering information can be used to generate displaced surfaces for various base surfaces without significant re-computation so that updated images can be rendered quickly, in real time or near real time.

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.
