try dim and adapt 0:

Unfortunately it doesn't do anything. Source image is still pixelated as you can see on the left Can't a large image be smoothed in a smaller jit.window size?

you can load into a matrix first-- patch and image attached. for speed with this method convert your image to a .jxf in max first, then use read instead of importmovie.

i think you need to use mipmap filtering when down-sampling textures, which is only available with non-rectangular textures.

Great, thanks! But it seems jit.gl.cornerpin doesn't like the idea, unfortunately

Otherwise I can't understand why it is not possible to smooth GL edges in this configuration :

i would do it like this:

Mmm okay I understand the process but I think only a Cycling74 programmer knows what happens inside the objects. Indeed, there is nothing saying why cornerpin is not able to process the GL stream. Some documentation about what are the possibilities and restrictions of that kind of hybrid GL objects will be great. Max XX? Anyway, the patch help much, thank you.

cornerpin not displaying non-rectangular textures is a bug, and this is the first time that I've seen it.

the technique i demonstrated for you requires no special insider knowledge. my answer came from having to solve a very similar problem for a recent project.

I have a similar problem with texture quality with jit.gl.model:

I would also be glad to know more about the possibilities and restrictions of Max' OpenGL.

similar solution, you probably want to enable mipmap filtering. you probably also want to enable @fsaa, and if on a Mac retina display enable @high_res.

Thanks a lot Rob.
