Does Houdini have point NURBS curves?

[magneto]

I don't know if it's the right term but in Max, there are 2 sets of NURBS curves, point curves, and CV (control vertex) curves.

In point curves, the points lie directly on the curve:

as opposed to cv curves:

Just wondering if Houdini does support #1?

Thanks.

Try setting the Method to Breakpoints.

From the help: Breakpoints - Click to place breakpoints, and have Houdini calculate positions for the control vertices.

If you want to have points that lie on a NURBS curve in order for easier manipulation in viewport, then unfortunately no. At least not that I've ever seen it. Although I'd imagine this would definitely makes thing a little cleaner.

But if you want points on the curve as a resulting effect, then there are plenty of options allowing you to do this.

Thanks guys, Breakpoints do exactly what I need

But you're aware that Houdini has a great help?

You can access it by pressing F1.

Or just click on one of the many '?' icons.

Yes I know but I am following video tutorials for now. Only look up the help when I need direct help about a parameter I know about already.

'Oldschool' once gave me a precious advice - he said:

Open the help and read a random help card.

Do it everyday.

It will teach you things you didn't know.

It will remind you of lost gems.

This is how you learn Houdini.

There are example files for almost any node - demonstrating tricks beyond your imagination.

Stuff that can hardly be put into a screen cast.

That's a valid approach, but I learn differently.

I prefer to see things visually first, read later. I don't disregard the manual, but it makes little sense when you still don't know large areas of Houdini.

Also this forum is for asking questions about Houdini, right? If you don't wanna answer someone's question, that's fine.

A lot of the questions you seem to be asking have direct answers in the manual. So by deliberately ignoring the manual/help and just asking basic stuff here you are practically asking people to type that stuff for you.

This is indeed a forum to ask questions about Houdini, but it would be a better place if those would be valid questions about stuff not directly documented, not stuff that fits in the category of "I'm to lazy to search the help, you do the work for me".

The manual makes perfect sense no matter how many areas of Houdini you know.

if you turn on breakpoints under display options you can grab and move them around in the viewport. for selecting the points you need to right-click on the selection filter since there doesn´t exist a hotkey for breakpoints.
