Modeling challenge: vehicular models.

[JSantocono]

Hi Audiophile,
T is the default hotket to change pivot of manipulator.......maybe you have another key set. Run tsOptions and on >T-Splines >Hotkey you can set it to the key you want. Remember that the T-Splines functions hotkeys are only avaliable when you are in EditMode ( HUD display on the viewport).
You can also use the Change pivot Icon.
Does this helps?

Hi All

A last minute entry, not sure if you are allowed more than one entry. Thought I would make something more organic see what Tsplines could allow me to make. Sort of ran out of time on this one but thought id show it anyway.
I have emailed the file to Matts address for evaluation.

Hi everybody!

JuanS, Thanks for your comment .......I am leaving another post for you to look at, it's a car concept, with rims and steering wheel.

I hope you guys like it and I'll be expecting your comments.

hy matt,
i send u a concept car yesterday, as u know...but i can not see it on the web page the real reasons why im writins to u is: it is very nice to help t-splines and partecipate to the vehicle competition but few of us can not really send the 3d model to the judges due to copyright/patent reasons. if they need some images in wireframe no problem but the model send to them is a limit for the competition itself.
keep going rhino should thanks u day and night, without it, the program would be a bit better then autocad for organic modelling eheheh

Hi Stef,

Sorry that I've been slow uploading your image. Here it is now (attached). Great work, as always. Thanks for sending this.

The purpose of the competition was to show that T-Splines is different from other modelers that produce organic shapes, in that T-spline models are smooth and able to be passed downstream to solid modeling packages. Unfortunately, it's hard to tell that from just an image. If you are able to share your model with me to pass onto our judges, I can assure you they will destroy it after completing the judging. However, I understand your concerns.

Best,
Matt

Excellent job, Fabio. Thanks for making a video--I've embedded it with my comments here:

Nice steering wheel, too. I was hoping to see a component like that. Just curious--did you use the bridge command?

Hi Matt:

Thanks for your comment .... Answering to your question, yes, i made, i developed the steering wheel and the wheel using the bridge command.

Kind regards,

Fabio Rios

Thank you to everyone who participated in the challenge. The winners have been announced on our blog

Congratulations to everyone!

Matt - regarding your comments on topology differences between SubD-models and Tsplines...
Is it in your plans to at some point add an automatic analysis which optimizes the Edge-Flow of a Model built following SubD-paradigms while converting it to Nurbs? As the topology-differences appear in a predictable manner this to me seems to be a suitable area of at least partial automation...
Maybe it's just me, but it feels kinda painful to manually destroy the harmonic lines of a well made
Mesh model by deliberately creating T-Points.And - frankly - I am equally hesitant to add these odd looking T-Junctions when starting a Tspline-Model from scratch...

cheers, Holger

Hi Holger,

Thanks for your note. The problem is that models created following strict subd-paradigms are not as smooth when converted to NURBS as those that use T-points. Since star points (which abound in subd modeling) are only g1 smooth, Rhino will not allow us to do anything besides split up the NURBS at every star point.

Also, regarding adding "odd-looking T-junctions", I think this might be an area of user education that we need to do a better job at. I frankly think they look prettier than star points for ending detail since they are smoother! But, seriously, thanks for voicing your concern--what makes you hesitant to add T-points in your model? Does it somehow make it seem like you have less control over the surface since T-points might still be somewhat foreign?

Yes, I understand that problem, at least at a superficial user-level .

Yes, when looked at in Rendered Viewmode...

I was talking about the mesh-flow.
Every Mesh-modelers instinct is to keep a model all Quads, to avoid Ngons and Tris. The result is beautiful to look at. While the the car-model you altered performs way better at conversion time it looks - ugly and "wrong" in comparison, at least when judging from the mesh-topology alone. This is
why I am hesitant to add these modifications manually - and I guess I am not alone with this.
That is why I proposed to perform the necessary mesh-adaptions as a - at least partially automated
process - when converting from imported meshes.


Edit: I should have said "when Converting from Tsplines to Nurbs". I guess it was the easiest for everyone who is trained in SubD-modeling to simply go on working like he/she is used to from
Modo/Silo/Hexagon... whatever SubD-package.

i like the alloy looking car, these are very creative stuff, if these are the cars of the future, id be scared. they look like they're gona come to life any minute. car parts are getting more innovative, led headlights, heated carpet, driver free cars.. future automotive would be very interesting.
