Having issues with the ray tracer

[andrestoga]

Hi,

I'm testing the ray tracer on a occupancy grid map and I'm getting the following results:

which shows a weird pattern because the walls are flat, as you can see in the following image:

I'm using 720 beans for the ray tracing. Any idea on what is happening?

Best,
