What addons use node-editors as the main working space?
Animation nodes and Sverchok are only ones I can find in google. Are there any other addons out there?
I am trying to find a reference code for node editor addons, which I can use as base for building my own addon. Preferably ones that use blender 2.8 api
City builder is also node based…
Also ModularTree these are good ones i remember directly…
As far as i’ve found these:
(If you don’t end up to the “Nodes” Category, click on Free > nodes).
have you looked at built-in script templates in the blender text editor ? there is one about custom nodes
This is a bit too vague, since you can split node editor addons and scripts into different types…
If you tell us what you’re trying to do with the Node Editor, perhaps you’ll get more conclusive answers.
I have a framework which is used to assemble simple math ops to form a complex math op. The workflow is well aligned with nodal logic. After the computations are done, I have to visualize them. I am planning to do this entirely inside blender as a POC.
I found this snippet to be helpful.
Any other resources you can point me to will be greatly appreciated. I need more clarity how to implement loop functionality that is in animation nodes and also a way connect a node to itself for recursive computations.
If you’re using a Custom Nodetree, that you can implement the loop functionality as you want (not so many barriers here)… You can use a conjuction of nodes as in AN, and do the looping stuff in your eval/execute functions; You can use nodegroups and pile them one after the other like i did here… Or you can define any another interface if you need it… Plenty of choices here.
I did one for Blender 2.79 that uses the compositing nodes, available at https://github.com/RokenPrice/Shadow-Catcher
Note: It doesn’t work with 2.80, and I’m not so sure I need to update it to with the new shadow catcher functionality (though I hope it extends to include reflections and caustics like mine does).
