Webinar: May 7: How to approach modeling with T-Splines

A support and feedback forum for Autodesk T-Splines Plug-in for Rhino users.

Webinar: May 7: How to approach modeling with T-Splines

Postby Matt Sederberg » Wed Apr 17, 2013 3:51 pm

Register now for this free webinar on Tuesday May 7, 10 AM Pacific.

Are you a fan of "Car Talk" on National Public Radio? In this popular radio show, "Click and Clack" demystify the complex challenges of everyday people trying to understand their cars.

In the spirit of this radio show, we offer "T-Splines talk." T-Splines gurus Kyle Houchens and Sky Greenawalt (aka "Click and Crash") will demystify the challenges of ordinary designers trying to understand T-Splines.

T-Splines offers designers the chance to make and edit beautiful aesthetic shapes easier than in NURBS, but we've found that designers well-versed in NURBS often have questions about how to best approach modeling with T-Splines.

In this webinar, Kyle and Sky will review user-submitted design images and walk through the process of drawing out a T-Splines-suitable topology on the images. This process of thinking through the topology layout (ie, how the faces and edges hook together) before beginning your model is a key practice that will greatly improve the quality of your models. Then, they will take one of the designs forward and actually create a 3D T-Splines model out of it.

Beginning and intermediate T-Splines users will benefit from seeing the thought process of Kyle and Sky as they approach creating these models in T-Splines.

Do you have a design you'd like some pointers on? Post it below. We'll try to pick 5-6 to use in the webinar, then get through as many as we can. If you have an interesting backstory to the design, your life, or your question, include that as well and we might read it on air!

Hooray for that. I enjoy hearing these guys share practical work methods and hints 8)
OK then an example... hmmmm.. lets take a streamlined HPV shell. Lets say I wanted to commercialise a HPV for daily use, add some stylish lights/indicators, vents, flares for some pop out low speed wheels and some subtle edges/creases for aesthetics and blend in a cool rubber running strip/bumper. The basis needs to remain aerodynamic though because that's a selling point. There is a mix of purpose in that there is a precise engineered form to adhere to but also the 'designer's artistic intent to satisfy.
In the past when I have tried to do stuff like this I have found my approach gradually makes a mess of the initial faired shape or that the bits I add somehow don't end up being as specific or perhaps designer cool as intended. I just can't seem to make/keep things sweet and the more I try to fix things the more small discrepancies I end up with or the topology just becomes unruly and then I get frustrated. The more intricate details I add the harder it becomes to retain my initial shape as well especially if then say I want to make a change in one particular region and it ripples out...
If I run a small business I cant really afford to make errors, be inefficient or have a substandard product. If I am going to mold quite a few shells from the geometry I want them to be as clean as possible and right first time. How do I do tackle this sort of tspline mission well?
Feel free to add other potentially problem modelling acts you can think to include with this example. Hope that is useful :wink:

Neil,

Great example! To help us talk more effectively to this, do you have any images/screenshots/models you should share to illustrate the problem?

Matt

Um not particularly. I rustled up a 3 min doodle for you though - attached. I'm sorry I didn't have enough time to make this a workable sketch. The front is a bit of a mess. :roll:
At the tail there is a stop light and indicators blended into a spoiler and around the cockpit an integrated wrap around headligh/indicators/mirrors/entry handle The sides have a flare/pod for the wheels, and if I had drawn it better there is a slightly raised bumper strip at the waist. Possibly there is a subtle crease along the upper part of the canopy to the tail deck. The nose has some vents. These items need to work closely with the initial teardrop shape. Hope this helps. Sorry its pretty rough. Feel free to use it or not or just talk on about various aspects of using Tsplines and typical problems. I think Kyle did a car tutorial or two along similar lines but holding the exact shape wasn't critical and Skye has done some keeping the shape exact for aero reasons but not doing purposeful styling along with it.

The flares added along the sides should bulge and blend in nicely in all directions and sweep out the back with the general taper of the body.
The vents at the front also need to be a distinct shape and blend in. They might have a slight outward flare before going in, nostril like, but the actual slots need to be geometric.
The canopy crease should be distinct but not sharp and taper in, perhaps with a conic rounding.
There shouldn't be any ripples or imprecision even though we are trying to do things with some style....better style than my sketch anyway ;)

Not sure, but you can get the answer from Wolfram Alpha.

Hi All,

Here's another example... It involves a fender that I've digitized in Rhino, cleaned up the wireframe, and wish to utilize TSplines to generate the surfaces. Any input the experts can provide here is greatly appreciated.

Someone had asked in the webinar registration about how to model a face in T-Splines. We'll touch on this briefly in the webinar, but here's a reference that can be helpful from Juan Santocono:

Hi,

Has this webinar been recorded and posted online anywhere? I can't find it in the Community > Webinars section of the site.

Yes I was wondering the same thing. I couldn't attend the webinar but I would still like to view the recording of it it. :wink:

We had some technical issues during the webinar so I don't have a recording of the whole thing, but here are the two main sections of the webinar:

Thanks, there's enough there for me to appreciate why I have been having trouble 8)
Aside from my usual struggles to make clean topology I can see I have been trying to achieve too much in one hit and all within the tsplines toolset. Wood for the trees I guess. :roll:

This was awesome and much needed.

The verdict I take from this is: Do several T-Splines, not one.

Makes sense. My problem though is that I've sort of become addicted to the smoothness T-Splines produces, to the point where I just don't ever want to have to deal with blending in traditional NURBS.

So that's created a strong desire to ALWAYS use T-Splines, and preferably one single T-Spline, for whatever I model, resulting in the trouble that Sky was talking about when he showed his car model.

Recently I've dabbled with meshes in Rhino only, so as to create T-Splines from them later. Not too successful though.

Thanks for posting the webinar.

Interesting to see the guys recommending using multiple t-splines or combinations of converted t-splines and regular nurbs. I started off trying to model everything in T-splines and got exactly the type of problems they described: overly dense meshes, the odd peculiar surface wobble etc.

Part of the problem was following tutorials for other software (like Modo) to learn quad-modelling. In those packages you can't use nurbs for simple things, so of course they model everything as a mesh (even nuts and bolts!).

Juan actually taught me last year that a combined approach is the best. I'm yet to master the combined approach such that I have flexibility in the model, i.e. avoiding a lot of rework if I need to make changes later on.

Good luck to everyone else on this modelling adventure!
