This is a laser projector, witch can project image, composed by lines programmatically. CAUTION PROTECT YOUR EYES AND THE EYES OF OTHERS https://youtu.be/9m3-xuqzcrI Primary thing is matrix_A. You can compose this matrix with any laser, any motor, any mirrors. Set point positions, distance to wall. To debug set to 1 variables: draw_samples = 1; draw_samples_p = 1; draw_samples_l = 1; You can set points count, matrix radius. Line width related to mirror size, matrix radius, distance to wall. To see the real line length, calculate math.tan(a_rad)*hx And update value at phrase CHECK IS THIS EQUAL. I don't know why openscad calculated it wrong..
