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..
