Finally got the slicing actually finished. I’d had a small bug in my bubble sort to fix the vertex winding which was messing up the polygon rendering.
One thing to note is that it has exactly the same bug as my c++ code where the translucent shadow volumes rotate as the camera rotates. I’ll probably be able to give this BP to @danielW and hope he can debug it.
Now I’ve exercised this demon, I can go to bed and sleep soundly before tackling ray marching tomorrow.
Take care all. Nighty night from NZ.
