Live viewer refresh during transformation

[Francois-Grassard]

Hi,

Is there a way to refresh the viewer during the transformation of an image, instead of refresh it only when we release the mouse buton ?

I don't see any option for that. :o)

Thanks ... :)

Live preview requires a lot more of opengl code, because the preview should not trigger a render (which may have motion blur, etc.). It's feasible, though (fetch the image and texture-map it with projective texture mapping)

Ok, I see how difficult it is to implement this kind of features.
Definitivly not on the top of the Todo-List ... :o)

As mentionned in another post, I'd prefer to be able to move an image using the arrow keys, first ... :)

After Effects uses adaptive resolution to help with the realtime positioning of things, or seeing what's happening when you scrub the timeline. Perhaps something like that could be implemented someday?

Moving an image with the arrows keys, great request! I second that request! :)

Natron already uses adaptive resolution, but preview drawing is in the OpenFX plugin, in the part called "interact".
