Slitscan

Hi, I’m trying to build my slitscan patch modifing the tutorial one but, I can’t draw each row, there is some jumps in the scan…

Here is an image. You can find in the attachment the TOE file.

Thank you very much.

Not sure, but one thing is that if your project is not running at 60 frames per second, the dropping of image into the Feedback image is going to miss some scanlines since it rises by some fixed number of scanlines per second. Seems like I had to swap the Over TOP inputs too - I haven’t looked at the original example so cannot compare.

So, after switching the inputs in Over TOP you don’t get any problem?

My project isn’t running at 60fps using CHOP Peform I get 24/25fps, I’m on a laptop with an Intel Core2 Duo T5800 2Ghz and a GeForce 9300m GS 512mb

There is not a way to bypass this issue? For example something that, instead of CHOP Speed, augment it’s value every frame rendered. Maybe I’m saying something strange, I don’t know.
