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.

@ut3usw

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

@ut3usw And I was thinking recently how to draw a circle with sinewave

@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.

@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.
