Apply shader for entire context

reno-'s icon

Hello,

I'm trying to apply a transformation (like a keystone) on a render
which contains several objects (jit.gl.sketch, and rr.gl.ogre), but
it's not so easy !!!

We write the shader, but I don't understand how to apply it on the
render.

Maybe someone hav a clue?

hi, there is a known solution to capture the entire rendering context.
documented (if im right- for origin search for "usetexture targetx, to_texture" - on Andrew B recipes)
i used it my own keystone patch, which i shared recently, and cleaned lately so here is a repost.
see the keystone sub patch for more.

it is fairly large so its in pat format.
