If you are in C++, use the function trace_rays () in the file ray_tracing.hpp to find out by how many rays each grid cell is hit. If you are in Python, install the library via the CMake file and use one of the functions raytracing.trace1d, raytracing.trace2d, and raytracing.trace3d, defined in raytracing.py. Also have a look at the test cases to verify your installation and to …

Grid Creation Strategies for Efficient Ray Tracing
https://www.sci.utah.edu/~thiago/papers/rgrid.pdf
when ray tracing a well-behaved model with N geometric primi-tives, the lowest ray tracing times using a grid acceleration struc-ture occurs when the grid has O(N) cells. This paper extends the theoretical analysis in two ways and then experimentally verifies that analysis for several geometric models. The first extension is

grid traversal by more than a factor of 10, and achieve ray tracing performance competitive with the fastest known packet-based kd-tree ray tracers. The ability to efficiently rebuild the grid on every frame enables this performance even for fully dynamic scenes that typically challenge interactive ray tracing systems. 1 Introduction and Related Work

A ray tracer can handle area lights in an approximate way, by replacing the area light with a grid of point lights. It can then cast a shadow ray towards each point in the grid. Using more point lights in the grid will give a better approximation. Of course, casting all those shadow rays can add significantly to the computation time.
