2d grid distorted when viewed in 3d?

@piinthesky I modified my code above. It runs at about 56 FPS with 320 spheres. The spheres don’t look as good as @Ignatz , but I increased my speed.

EDIT: Changed my code again to add the white verticle posts back. FPS now about 52.

Mine does nearly 500 before slowing down, but I do have a slightly faster iPad, and I didn’t draw posts

Just an update on my efforts to make a 3D neutrino event display with Codea. This time for the KM3NeT telescope with 116 detection strings…


To keep the fps high, in the end i used full 3d spheres (not billboarding), but only display the spheres close to camera. Very happy with the performance.
