Neural network algorithm for solving ray-tracing problem
https://ieeexplore.ieee.org/document/1201979/
This work is dedicated to the study of neural network method for solving of ray-tracing task, which appears in 3D visualization algorithms. Physical representation of the task is the problem of finding the nearest point of the "vision" ray crossing with the surfaces of the scene. Application: Real time 3D visualization, rendering of the complex scenes, containing …

Neural Ray-tracing is an extension on top of NeRF & VolSDF to allow for efficient ray-marching, so that dynamic lighting conditions can be rendered. This is done by adding an additional network that accounts for lighting based on position and viewing direction, as well as learning correct surfaces such that an SDF can be quickly raymarched.
Points-connecting neural network ray tracing - PubMed
https://pubmed.ncbi.nlm.nih.gov/34469953/
Unsupervised neural network ray tracing (NNRT) to calculate a light ray path connecting given points in a gradient-index medium is proposed here. If two points are given, the NNRT can provide a light ray path passing through these points without knowledge of the light ray direction. Maxwell's fishey …
End-to-end sensor and neural network design using …
https://pubmed.ncbi.nlm.nih.gov/34809257/
The proposed ray tracing model makes no thin lens nor paraxial approximation, and is valid for any field of view and point source position. Using the gradient backpropagation framework for neural network optimization, any of the lens parameter can then be jointly optimized along with the neural network parameters.
