Can you please explain what you mean by "...stops working"?
Also can you compile the code (unaltered) and run that or does it only work with some pre-compiled version of the program? (Some of the image files have dates that are about 18 months earlier than the source file.)
Finally does this work in real hardware? If so then it could be a bug in th

When you say "movable" it is supposed that you mean to scroll the picture either at an horizontal or vertical direction. Although Codevision supports many graphical display chipsets, each one having its own features, the generic option to code that, irrespective to the LCD manufacturer, could be by plotting the same picture at each new update but s

Your attachments don't work.
Just because you used the same software and physical setup doesn't mean you should expect the same results. What convergence criteria did you use? Did you specify a seed mesh? What's your final tetrahedron count?
The mesh quality has the possibility of drastically altering results.

I know it's probably a bad idea regarding blinding someone.
But as opposed to phased array design that would probably mean more expensive.
What about spinning a laser and creating a 3D map of the image returned from this spinning laser.

Could you describe more specifically what you are doing? I'm not sure what you mean when you say you want to quantise an FFT signal. Any digital signal is quantised, so the input to the FFT and the output are, in general, quantised already.
If you want to compress it, I suppose there could be many ways of doing that. Does your compression need t

I guess you mean whorls and ridges?
You could compare the slopes of lines (following a line pixel by pixel). Where slope changes, that must be a singular point.
However following a line may not always be possible, since you cannot be sure of the quality of the image, and you cannot be sure there won't be gaps in lines.

If so then you need to change the operator to '>0' (or '>=1').
