Ray Visualisation doesnt seem to always capture reflections

[tomflint22]

The VTK write-out of the ray paths doesnt always seem to be working correctly.

This can be replicated by running the Plate2D case and then observing the rayQ fields, which is what the code uses for the calculations and comparing this with the VTK paths as shown below for the 1st timesteps. Maybe this is just an issue when the beam is not normal to the surface as some reflections are picked up later.

Hi, Tom. To check, I understand: Is the problem that the reflected rays not being shown in the VTKs?

Hi,
Yeah so the code is working correctly in terms of calculating the reflections and deposition, it's just the VTK is not being written correctly. If you look at the VTK's they should lie on top of the rayQ (andrayNumber) fields; these 2 fields are the original way to visualise the rays.

That's what I was trying to show in the image above. So the VTK rays should come in and be reflected at 90 degrees like the rayQ field is
