TOP > CHOP > TOP How to do this conversion and get the same pixel dimension image output in TOP that you started with? I am trying to normalize an input image by going from
TOP > topto CHOP > Math CHOP (adjust range) > chopto TOP
but am getting just a single row of pixels output.
There is the Math TOP or maybe even the Level TOP that probably can achieve what you’re going for.
Going from TOP to CHOP and back to TOP again is extremely inefficient as TOPs work on the GPU and CHOPs on the CPU and anytime you go between the two there is a very computationally expensive “download” and “upload” process to get between GPU RAM and regular RAM.
I agree with Peeet, you can do all the calculation you need inside Top world (Math Top, Level etc.) And if you need something more elaborate, Glsl Top is you friend, with a very efficient GPU use. You can find many tutorials on how to do it.
