The ray-tracing algorithm relies on 3D-model reconstructions of the urban ... The 3D scene is used to calculate the multipath (reflection and diffraction) caused by the buildings and objects around ...

The algorithm helps optimize a new imaging approach called intensity diffraction tomography (IDT). Jiabei Zhu from Boston University will present this research at the Optica Imaging Congress.

With Meta’s Acoustic Ray Tracing, the company says in a developer blog post it can simulate sound reflections, reverberations, and things like diffraction, occlusion, and obstruction—all ...

Topics will include paraxial optics, aberrations, two element systems (such as telescopes), and dispersive optics (such as diffraction gratings and binary optics). We will discuss transfer functions, ...

A ray tracing algorithm will track rays of light from a light source to an object. Once the light hits that object, the algorithm can account for how much light will be absorbed by the surface ...

In addition to this technique, Intel is also introducing an efficient path-tracing algorithm that it says, in the future, will make complex path-tracing possible on mid-range GPUs and even ...
