Nuke Python - Get viewport/DAG size
show user profile  br0t
Heya,

I want to center my Nuke view on a group of nodes, zooming in exactly that much so that all nodes are visiblei in the view.

I have not found a way to get the current viewport size or similar though, which I need to calculate the correct zoom level :/

I know there is nuke.pan() and nuke.zoom() and I can get node positions and centers and such, but that bit is missing.

Any ideas? Can you even get that information?

never get low & slow & out of ideas

You want to move the viewport during a script? Or is that the whole script, because you could just pres 'f' :)

these examples seem quite useful though?

Yes I know, I want that exact functionality, but not for the whole script, just a subset of it, e.g. my currently selected nodes.

Haha I did the most weird workaround now: I wrote a function decorator that before calling a function (which creates the bunch of nodes I want my view to zoom/fit to) will buffer and remove the whole scene, execute the function, zoom to fit ('f' basically), then recreate the buffered DAG afterwards.

Still wondering why that works :D Feels dangerous, but I just used it successfully on a very complex script with lots of expressions etc.
Nuke is really awesome in its possibility that you can simply copy a node tree and have it as text fully functional in the clipboard.

Heh that does sound scary but as you say.. just text so can't go too wrong you'd hope!

really helpful having ascii

I've made tools at work for all kinds of things, copy and paste over network, build nuke scripts with a text file rather than command line, useful!

Hm for some reason there is a problem though.

I have this giant node tree, that I buffer to a temp file and remove. Then I create a few hundred nodes based on some file. Afterwards I use nuke.scriptReadFile(...) to get back my old DAG.

For some reason it connects one of the new nodes with two of the nodes that come in with the restored DAG. Oo"

I have to finish my task today, so for now I will not use this hack :/
