Copy Houdini :) #22

Open virtualritz opened 5 months ago

virtualritz commented 5 months ago

Houdini is probably the app to look at, as an example, what to implement for a node graph editor. They've been around the longest. TouchDesigner is btw a fork of Houdini. It's long enough ago they may also have added some novel ideas but I wouldn't know.

You can download and play arround with Houdini for free (Apprentice version).

Stuff of the top of my head:

(Grid) snapping
Comments
Underlying nodes with a named, colored rectangle (that stays)
Layouts
Adding vertices to connections to make stuff clearer/disentangle
Coloring nodes/vertices/edges of a graph
Changing node shapes

I suggest watching this video for some inspiration.

I forgot:

Buttons in the otherwise mostly unused space of a node's title bar.

Houdini uses them to turn nodes into templates, mark them for preview or for pass-through.
