How to bend or curve a video?

Hi everyone,

I’m looking for a solution in Jitter…

Does anyone know how to bend a videoplane (curve along the Z axis), or may be “spherize” a video?

Any help would be appreciated. Thanks in advance!

Create your own ModelMesh with the desired UV-mapping, load it with jit.gl.model and send a videomatrix or texture to it.

Or start having a look at jit.gen / jit.pix / jit.gl.pix – There are some tutorials out there that describe how to create displacement solutions. Like this one here: https://www.youtube.com/watch?v=AFyBW5mpRkc

As you can see, there are several ways. Here’s another — it uses jit.gl.mesh and jit.gl.gridshape:

Wow! Thank you for your quick responses!

As I can see, there are several possibilities; and I did not know the jitter recipe 18. It’s exactly what I needed!

Again, thanks for your help!

hm – may i suggest here a custom version, which uses a custom abstraction, which is just slightly more handy, in that circumstance, than jit.cellblock – just slightly :

you’ll need the attached abstraction “matrixctrlf+-”
