Aspects of the present disclosure involve a system for performing ray tracing between augmented reality (AR) and real-world objects. The system accesses, by the mobile device, a video depicting a first object. The system obtains, by the mobile device, a three-dimensional (3D) model of the first object. The system applies, by the mobile device, a ray tracing process to the 3D model of the first object to estimate an optical effect on a portion of the first object relative to a second object that is depicted in the video. The system modifies a visual property of the portion of the first object based on the optical effect relative to the second object.

Ray tracing between AR and real objects

The present invention teaches a real-time hybrid ray tracing system for non-planar specular reflections. The high complexity of a non-planar surface is reduced to low complexity of multiple small planar surfaces. Advantage is taken of the planar nature of triangles that comprise building blocks of a non-planar surface. All secondary rays bouncing from a given surface triangle toward object triangles keep a close direction to each other. A collective control of secondary rays is enabled by this closeness and by decoupling secondary rays from primary rays. The result is a high coherence of secondary rays.

System for non-planar specular reflections in hybrid ray tracing

Accelerating structure for hybrid ray tracing is characterized by high locality, wherein scene changes are updated locally in one of its hierarchies, without effecting other locations in the structure. Reconstructions of accelerating structures of prior art are replaced by low-cost updates. The efficiency of traversals is improved by a double step traversal.

Method for constructing and traversing accelerating structures

Hybrid ray tracing method for generating photorealistic reflections while keeping coherence of secondary rays. The coherence is achieved by decoupling secondary rays from primary rays, handling bundles of secondary rays with collective origin and collective destination, attaining high parallelism and high utilization of GPU.

Coherent secondary rays for reflections in hybrid ray tracing

A computer-based method for hybrid ray tracing to generate photorealistic reflections of objects on a non-planar reflective surface. Each triangle of the reflective surface is handled separately for secondary rays to generate its own physically correct reflection. A final gathering of partial reflections results in an aggregated non-planar surface reflection.
