Hello Rômulo, sorry to bother you with another question.

When creating a bowl-shaped object such as the cube with a hole, I was expecting to get multiple echoes back from the object as sound bounces back and forth within the bowl and then back to the receiver. I am however only seeing the primary reflections. Do you have any idea what this could be caused by? hollowcube sonar

Hi @AronNoren, this is a known issue: https://github.com/romulogcerqueira/simulation-normal_depth_map/issues/20

Feel free to contribute!

Thanks for the answer Rômulo, I see the issue now, complexity would grow very fast if all rays were kept and It's not trivial to determine which rays to keep if we allow for some self-reflection?
