I'm actually working on some small shader (GLSL) in order to do some process on video. 

I currently fronting a small barrier. How can I make a multipass fragment shader ? How can I render my scene into a texture in order to repass them into my shader process ? 

If you got some examples patch, it will be really helpfull.

jit-gl-multipass-rendering-shader

perhaps you could use few connected jit.gl.slab objects?

it seems to be part of what I was searching for.

yes,
it seems to be part of what I was searching for.
I'm doing some experiments, right now.
Thanks,

If you want to render to texture, there are plenty of example patches. Most use 'to_texture' message to jit.gl.render, but you can also use @capture with jit.gl.sketch and its draw_objects method.

If you only need to render to texture a single object, @capture is the easiest method.
