I've seen from the jit.gl.pix td.repos example that texture2Drect = sample(in1, norm);

Could someone point out what I'm missing.

what-is-texture2d-in-jit-gl-pix-codebox

The problem now is how to obtain a smooth "rain texture"... it seems there's some kind of antialiasing active in the shadertoy player, but I don't know how to reproduce it with Jitter.

super cool guys.
for the record, you can replace uv = cell / dim; simply with the gen operator norm


Thanks for taking the time to do this, its made (again !) a lot clearer to me how to convert things into codebox. :)

(plus for the wiki tuts that I'm working on converting)

Have to get in my head that codebox handles things like this

So in codebox is there no "real" difference between texture2D and texture2Drect ???

I think that the 1 plane 2d texture is just probably a high resolution image. If i put the dim setting on the jit.bfg to 256 256 I get a pretty smooth rain effect.

Have to get in my head that codebox handles things like this
vec2 where = (uv.xy-raintex.xy);
to this
where = uv-raintex;

I think the trick was that you didn't need the vec() wrapper in assigning to "where". This looks pretty similar to me:
