Hello, here is what I would like to do and I don't know how to do it...

I want to "slice" an image in 4 horizontal bands (4 rows) and have those rows move horizontally independantly one of each other. Of course using openGL...

I tried to use :

[jit.gl.bgf @basis noise.checker @scale 0. 4.]

I have 4 rows/bands, but can't move each of them horizontally.

Thanks !

Not sure what you want exactly.

Here's an example giving you 1 layer for each horizontal slice that you can move, rotate, scale, etc. individually, based on [jit.gl.subtexture] and simple math to get the dim and offset of each slice.

Or if you want to strictly displace bands horizontally, you can use [jit.fx.repos]:
