I have a SPS from a digested mesh. I try to detect which particle is in the path between a point and a box. But when I draw the ray with rayHelper, the rays are not passing through the particle but close to it. Below is a playground to illustrate.
As you can see, some rays are missing the SPS mesh.
And when I try do detect ray intersection with one box, I have some rays tagged as intersecting the box which are missing it when I draw them as in the playground below.
Am I missing something?
Thank you for you help.
