For something like 'path' shelf setup, I think the best place to ask is Houdini forum, maybe there is someone from SideFX team able to say about reasons for such setup. Don't believe a lot of Houdini users use this thing.It is setup, by structure (not by functionality) similar to Maya shelf setups like Flow Path. It creates a bunch of SOP nodes and CHOPs, in order to get 'oriented' curve, suitable for calculating the orientation of objects constrained to path. By using MMB over 'ordinary' curve created by Line or Curve SOP, you'll see only the P (position) attribute, while last SOP in 'path object' displays calculated normal and few more. By the way, some created SOPs are old, deprecated versions.

But putting that aside, the thing I really wanted to know is, what’s the practical difference between a path and curve in Houdini? I’ve learned I can path animate on both, but each creates a “curve” in different ways and I’ve been unable to determine what might be common or similar between them. I’m finding paths to be very cumbersome because they create so many cv objects that are not part of a unified path object. I can see advantages to that but the disadvantage is that large paths are difficult to manage. And curves seem significantly difficult to edit with precision, at least easily compared to paths. So whats the difference? Why one vs the other and what uses are they best for. Joey ------ Softimage Mailing List.
