experiments for various octree construction schemes. We further compare our predicted cost to the average cost of shooting a ray while rendering the image using a simple ray tracer. Our experiments indicate that the accuracy of our predictor does not depend too much on the ray distribution, for distributions produced by the ray-tracing and

Ray tracing is extensively used in urban and indoor multipath radio channel prediction. A ray tracing model finds the dominant raypaths between a transmitter and the receiver, considering the geometry of the environment. ... but at the cost of increased preprocessing times. The Munich database is tested for grid resolutions of 50 m × 50 m, 100 ...

Ray-tracing predictions are good when detailed information of the area is available. But the predicted results may not be applicable to other locations, thus making these models site-specific. ... The COST 231 indoor model simply uses a line-of-sight path loss with an indoor component: (3.22) where S is the outdoor path, d is the indoor path, and
Intersection Prediction for Accelerated GPU Ray Tracing
https://dl.acm.org/doi/10.1145/3466752.3480097
We explore how to integrate our ray prediction strategy into existing GPU pipelines along with improving the predictor effectiveness by predicting nodes higher in the tree as well as regrouping and scheduling traversal operations in a low cost, judicious manner. ... On a mobile class GPU with a ray tracing accelerator unit, we find the addition ...
