Which curve to use?


(Vidigiani) #1

Hey all, been forever since I’ve been here, or blending for that matter, but I am flirting with the idea of getting back into it. Since its been a while, I’ve forgot all the cool tricks… this should be a basic question tho.

I want to create a nurbs curve that is closed and have in interpolate the faces in the curve. An example of what I mean:

Any help is greatly appreciated! Thanks all!

P.S. looks like the images might not have transfered well… To get to them:

  1. go to www.suurland.com.
  2. go to “gallery”
  3. click on “new beetle”
  4. click on “modelling part 1”

Fig 07 and Fig 08 are the figures I am using as an example.

good luck. blender’s nurbs are by no means extraordinary. infact, i’d go as far as to say that they’re pretty awful.

I’ve never really used nurbs, never think I will. Subsurfs are pretty nice.

Welcome back…

Add a nurb circle

Subdivide it,

Move nodes…

Nodes are interpolatory when they lye on the line going from previous node to following node

Hey S68, its good to be back… and good to see that some of the Blender greats are still around :). I will give the NURBs circle idea a shot.

I used to use subsurfs a lot and they rock cause you can work with a low number of faces and then render with a much higher number… Just wanted to try something new >:].

Also, if NURBs are somewhat weak in Blaneder, is there a good alternative shareware/freeware app out there that does them well? If I could do some work there and import into Blender that would be pretty cool :).

Hey man! Long time no Blend!

I woul tend to stay away from nurbs at all cost in blender. Do this in poly’s with sub-d. You will have more control over the mesh that way. But it is your decision. So good luck and I can’t wait to see it!

For NURBS I heard of NURBANA, but never seen it :wink:

Heh, I was just about to say nurbana as well. I know rhino is one of the bigger ones, I don’t know of many free ones, but I’m sure they are out there.

to make a car i think meshes are still the best option in blender…until you have something like what other 3d programs call patches.but you certainly have to be a good mesh-modeller.


(mrmunkily) #10

there are no half decent free nurbs modelers. Nurbana is not good at interpolations, unfortunately, and has really none of the tooos neccesary for anything remotely complicated.

I’ve used it recently. at least the thing started. last time it refused to even do that.

try rhino3D

http://www.rhino3d.com.

satish.

Yeah, Rhino3D looks awesome. I downloaded it, but its too bad you only get 25 saves before you have to fork out $700+… I’m just not that rich lol.

What was Spatch, spline based? isnt’ that the same thing? It was one of the first modelers I found years ago, and there are still people using it.

http://www.geocities.com/getspatch/index.html is the home page

and this guy has a lot of links, etc…

it’s really a basic modeler, but you may like it? you can export to vrml then into blender. Of course that turns it back into polys.

Well, at least your question reminded me of it, hee hee hee, like an old friend, I think I’ll play abit here… LOL

Love Ingie

If you really want to model nurbs/splines, go get Hamapatch!

You can get it at http://www.geocities.com/hamapatch/program/index.html

Personnally I find splines rather hard to model anything non-organic with. But I´ve seen really great models made with Hamapatch.
