generate/filter nodes

Happy new year!

Cant find any information what separates these nodes from the vanilla empty node?

Gustaf

generate and filter are template nodes that can be used when building your own geometry-related nodes. The default node (called "node") is used for general-purpose operations, such as math or string nodes.

generate:

• Sets the output type to geometry.

filter:

• Extends from the generate node.
• Has one input port, shape, that takes geometry data.

You can see the definition of the nodes in the corevector source.

so apart from having some extra presets on the input and output ports they do the same thing?

Yes, they have the same core functionality. The general idea is that if you write nodes that manipulate geometry, you extend from generate or filter. Otherwise, extend from core.node.
