- Adding execution code for Node trees. Was a bit a puzzle, since I want
it to be multithreading by design. This now is solved by defining a
stack per tree for all data that's being written into. This stack, which
resides now in the NodeTree itself, then can be allocated per thread.
- For testing pleasure, I've added a 'mix node' and a 'show node', so
you can already see it do something. :)
- reshuffled structure, to put things nice together, and have easier node
adding. Current state is still WIP though, structure might change.
For the record; new file node_shaders.c will contain all shader node
definitions, apart from the drawing callbacks.
Next: I'm going to check on Andrea's work on icons now, since this is very
much needed for true shader/composit work.
Now back to release work...
- delete/duplicate with connection links
- type awareness for sockets
- make connections checks for max amount of possible connections
- added dependency sorting of node list
- cyclic connections are drawn red now, press Ckey to see the other bad
cycles.
- added UI toolkit support in nodes (try shift+a)
So, almost ready for execution code. :)
- Sunday merger with bf-blender
- Foundations for new Node editor in Blender, generic framework that can
be used for Material/Texture, Compositing, Logic or maybe even Sequencer.
Note: this doesn't do anything yet, nor save! Is just to get this nice
in CVS now. :)
