Beautiful.
Did you do any optimization to minimize the way the ray has to run? Or does it just work well enough?
@deusfigendi Absolutely. I use a greedy solver to minimize the 'air travel' of the beam between lines. Without it, the refresh rate would tank because the beam would waste too much time jumping around.

Yea I guess so, but you still go back to 0/0 every frame?

@deusfigendi Good catch! Yes, I currently force a transit from center (0,0) at the start of the frame. It helps with centering on my specific scope setup, but avoiding it would definitely be more efficient.

@ut3usw bravo

xorox, you can draw a circle with two sine waves but you also get cool shapes if you change their frequencies and/or phases relative to each other

@ut3usw That is impressive work, congrats

@poleguy yes, ty! In real time wasd control.
On video below it’s how I see it on pc screen (with actual audio). -
@ut3usw do you have a way to contol the intensity? So you could switch off during the non-travel moves.
@gunstick i hope, i can! that oscilloscope has a z probe.

On the other hand this makes a cool "projection beem" effect

@ut3usw that is superb.
