Title: Porsche 921 - WIP
Post by: yotah1 on May 31, 2013, 02:25:46 PM
Hi everybody.

I recently sketcheda Porsche 921 vision for, hum, well, Porsche  ;D

So here is the sketchboard I did :

(http://img845.imageshack.us/img845/5685/porsche921presentation.jpg) (http://img845.imageshack.us/i/porsche921presentation.jpg/)

And here are some work in progress renders and screenshots (I render it regularly when I've done some extensive work on the design, just to check it works well when lighted and shaded, it helps to see the problems).

Right now, this is for about 2 days of work. I've got to modify the windows as I'm not happy with their shape (top of windshield is too round, side window corner window don't align properly...), fix a bump on the shoulder area in the body, and later I will pull out the fenders a bit more. Tomorrow : bumpers (and the mods).
I hope to get it mostly finished by middle next week.

Thats really great work - I really like the concept sketches you have done. Could you tell us what software you are using for building the car? and what did you use for the concept work?
Title: Re: Porsche 921 - WIP
Post by: yotah1 on May 31, 2013, 02:36:25 PM
Handsketch and Photoshop for the design sketches / Autodesk Alias 2013 for the modeling.

Great work matey and thanks for the info - really like the PS renders and I like the concept of basing it on the 928, which I've always liked the look of.
Title: Re: Porsche 921 - WIP
Post by: edwardo on June 01, 2013, 10:03:47 AM
This is real nice, for several reasons. I'v always loved the 928, particularly the early ones, and thought it's well overdue a decent update. This is definitely on the right tracks in my opinion. Your small side on sketch is bang on - very faithful!

Thanks for sharing an insight into your process. Its really helpful to see how you go from sketch > sketch render > putting first surfaces together, and seeing how one might go about starting to build a car and communicate the form clearly using minimal surfaces.

I can see how keyshot can be used in parallel with modelling as basically the best surface evaluation tool in the biz.

Thanks
Ed

Thank you guys :)

Yes Ed, Keyshot is for me a really good and quick evaluation tool, especially as this is a sketch to 3D process, which I normally don't do (usually I go through a clay model before doing the CAD...).

Here's for today's work :

the fenders have been pulled out, wheels too and added a bit of camber to them, all the body side has been cleanly rebuilt as I had a little surface bump on the shoulder line. This was tricky to remove, it took me 6hrs and about a dozen tryouts! The windows have been changed (their shape, not the surfacing), and the rear bumper is getting it. The lower valance on the rear bumper will need a new design as soon as I clearly sort out what I want to do with the diffuser and exhausts. The tail lamps will need work (right now I have only the outer skin of the glass) inside and the body must be finished around them. Tomorrow I'll get on the front bumper, and finish the rear bumper.

Remains :

some interior for rendering purposes
mirrors
lamp details
underpanels
shutlines, etc

A few more renders are coming with the current setup, then I'll spend some time on HDR Light Studio 4.0 to get some cracking HDRIs and do more shots.

The headlights will be reworked, I just rushed something in in order to do the renders, didn't really do any design on it.

Last two for today :

Regarding sending it to porsche, well that's already done, as I've recently applied for a job there, and this project is kind of my "so, do you hire me or not?" card  ;D

Well, if I were George Porche (or whatever he's called) .. I'd hire you ... like yesterday.

Now just do a killer job on the lights, cuz as you probably know .. recent cars often have lights you could stare at for 20 minutes .. even KIA's for god sake !  Imagine, just a few years ago they were just flat glass or even with cat-eye structure, that's it ... now, some are little pieces of pure art.

Title: Re: Porsche 921 - WIP
Post by: John B on June 07, 2013, 12:25:30 AM
love the concept and there are few if any changes that I would personally make...

that being said, here my 2 cents

1. I would play around with the idea of a retractable spoiler (similar to those you see on most cars in this cars class, even the new Boxster has one)
2. There is something that bugs me about having the wheels be that solid orange color, I would suggest adding black (or dark grey) accents to them, it would make the wheels really pop
3. The windows at the moment seem a bit too flush with the body so it might not be a bad idea to recess them slightly
4. Tucking the front of the hood down below the front bumper (similar to the 918 Spyder concept) could also add some real flare to your car.

Other than that extreme nit picking I have to say you've hit the mark on this concept and I look forward to seeing your finished model :D Hopefully Porsche likes it as much as we do.

Title: Re: Porsche 921 - WIP
Post by: yotah1 on June 07, 2013, 03:53:52 AM
Thanks for the great feedback guys :)

John, I will answer point by point :

1. no retractable spoiler as the shape of the car offers already quite some downforce with the rear spoiler integrated behind the rear window. Also, it's a 928 modern interpretation, and the 928 was clean and simple, no extra stuff, no shiny shenanigans and so on, so I want to keep that way of thinking and do a "clean" design. Also, the 921 is more of a 4 seater autobahn cruiser or weekend driver than a full on sports car, so while a wing makes sens on a 911 with its heritage and philosophy, on a modern 928, it makes a lot less sense.

2. i personnally like the wheels painted like this, it stays simple. Once again, doing a diamond cut, or two tone treatment, would make the design of the wheels quite complex visually, something I want to avoid. I know everybody does super crazy finishes nowadays on cars, but I'm a guy who likes simple and efficient things :D

3. the windows are flush because it's easier to model, and on a "vision" model, I don't see the point of spending a lot of time on doing the gaps and all like a real car, as what i want to show is a design, not the windows rubber joints for example. And anyway, showcars are done with super flush windows :)

4. same as the previous points, i want to keep things clean, and that's not a racecar or supercar, so no vents on the hood, nothing crazy. Just stay clean.


But the headlights need work (but still with a simple and nice design).

Sir, you are truly a master of your 'game'. This is a beautiful outcome and by the looks of it a viable one. I think its neigh-on perfect, and I whole heartedly agree with you about avoiding fussy spoilers and 'floating' front ends. What you've done is thoroughly on brand and oozes porsche DNA. However, it is your process that impresses me the most. My hat is well and truly off!!

Im about to make the jump from rhino to alias (tentatively). Seeing your work has got me quite excited about this migration. Any suggestions of good books or resources would be very gratefully received as I will be 'teaching' myself.

Thanks again for sharing - there is some impressive work on this forum, but yours is in the next stratosphere!

Well, Alias is, how can I put it..., a PAIN to work with  ;D
But I'm a bit of a crazy guy according to my friends so I only work with Alias!

To make it simple, it's all about the quality of your initial curves, and always work with squares. This software only understands squares, and clean ones only! So clean basic surfaces, and then I basically use 2 tools for the rest : Tubular Offset to trim my surfaces where I want to put a radius, and then Freeform Blend in Curvature G2 or G3 mode for the radius itself. This way, it allows you quite some freedom of editing along the way. Apart from that, I pretty much have no idea what all the other tools in the software are here for, but they definitely aren't here for me  ;D
Title: Re: Porsche 921 - WIP
Post by: guest84672 on June 07, 2013, 07:06:25 AM
I heard that before from some true ALIAS masters. All they ever use is a handful of tools. Sounds like a great modeling tool to me once you get rid of all the other stuff. And it would be easy to use, and then it comes down to your craft and creativity. Kind of like KeyShot. ;-)
Title: Re: Porsche 921 - WIP
Post by: Speedster on June 07, 2013, 07:51:37 AM
I totally agree with the simplicity of line.  I keep coming back to these images, and "don't see" more every time.  Hard to describe, but my eye just flows right along the form, with no breaks.  The hardest part of good design is to know when to stop. 

I've had the privilege of working extensively with the great auto designer Tom Meade, now in his 70's, who is now working on his Thomassima IIII.  (Google Tom) He told me once that he draws his inspiration from classical art, like the flow of a windshield from studying the kneecap of Michelangelo's David.  It may sound strange, but that's where, in my opinion, great design originates, not from stealth fighters.  So much design today is what I call the "Suppository School of Design".  Again, that's just my opinion.

I'm just now getting my feet wet (soaked!) in subD modeling with MODO and nPower for SolidWorks.  Take a look again at the wireforms. There are so few polys!  No wonder the lines flow as they do.  I've learned a lot just studying them, and I thank you!

So- this design is perfect! Including the orange wheels.  End of story, in my book.  If you don't get your position at Porsche you should start your own car company!

I'm fingers corssed for the Porsche application, we'll see what they say.
I agree with you Speedster regarding the design philosophy, nowadays a lot of guys just draw more and more stuff, and what i've learnt in my little experience is that things that last are simple and clean, they go to the goal without taking any detours.

Yes indeed, Alias is a NURBS software, it doesn't do polygons.

But still, there aren't many nurbs on the model, I tried to keep the modeling as clean as possible to do a proper job.

I used to work with a guy that went upto G7 continuity at times. Could never really understand why, or in what circumstance you would need G7 surface continuity. never go beyond g3 myself

Yes, that's the right way to do it. :) However, the planning and thinking process before even drawing the first curve can be quite challenging.
I mostly use SolidWorks, in which complex surface modelling is guaranteed to become a frustrating and cumbersome process. Mostly because of how SolidWorks handles a history tree with zillions of complex features. Feature errors and basically broken parts upon rebuilding are common in SW when you're pushing its capabilities for creating complex geometry.

Hey, Dries- take a look at the nPower Surfacing for SolidWorks plug-in.  It's a mindblower, even in its infancy.  Been using it for about two months now.  subD for SolidWorks!  http://www.npowersoftware.com/NewPowerSurfacingOverview.html (http://www.npowersoftware.com/NewPowerSurfacingOverview.html)

Just caught this on FB, great work sir!

I'm just about to invest a small fortune on Alias (soon as I clear some backlog TT  ;) ), so wish me luck! I know it's a total pain to work with, but SolidWorks just doesn't cut it for surfacing. Time to move on.

Good luck with the job application.

Nice work yotah,!I read you are working with Alias,(uhuhu how much painfull is working with?)so i suppose you did with Class A Surface..i'm working on automotive "sector", so i know Alias, and his usage;but whi u didn't do with Catia V4 (unix os), it's more simple to use and friendly. Class A surface are made for real production product..that's needs it.
so it's mean all surfaces that a consumer normally seescan be considered class A surface. The outside of a an automotive floor console would be class A, but the inside surfaces which normally include manufacturing flanges and attaching surfaces would be class B.QUALITY - refers to surface topology. Position, tangency, and curvatureacross surface boundries, and internal patch structure.

I've been working as a car designer for 3 years now, so I'm quite familiar with Class A surfaces  ;D

I used Alias because that's the one I know how to use, and I've never used Catia in my life. And given that now I can quite quickly get my model done, and do it properly, I don't see the point of spending time learning a new software.

Beautiful... I love the first rear shot in what looks like gun metal grey...

Would you be able to divulge which Du Pont paint you used, if indeed you did ?

Also, did you use a standard HDR image that ships with KS ?

It's not a DuPont paint (I had a look at these, but you can't customize them, so for me, that's just plain stupid and useless). It's a metallic paint, customized.

HDR is one of the standard studios included in KS (don't remember the name of it, it's in the last 10 in the list...)

It's not a DuPont paint (I had a look at these, but you can't customize them, so for me, that's just plain stupid and useless)

That's because they're DuPont colours...why would you want to customize them?

Were the sketches posted on Simkom a while back? I feel like I've seen them before. I always liked the sketches, but seeing it in 3D with accurate proportions is great; it really is a very pretty car. I'd love for Porsche to bring out a 944 successor.

Great work!

This is an impressive model, and impressive renders too. NURBS is the way I like to do mechanical models, I know nowadays everyone in the VFX industry uses subdivision surfaces, that are good for their flexibility and ease of "sculpt" but if you have a design idea, and a clear design intent, starting from curves and building with NURBS is the most robust path. There's always a debate about what software to use: "why didn't you use NX, why didn't you use Catia, why not Alias"... in the end it all comes down to what you are more comfortable with as Yotah1 said (I use CREO Parametric for mechanical modeling, because I know it and I feel comfortable with it :D ).

In my opinion, the problem with not being able to tweak the DuPont paints is that they are so highly dependent on the HDR.  Perhaps several "DuPont Optimized" HDRI's would be helpful, but...

Hey Anthony,
What kind of HDRI did you use for your scene?
Did you use HDR Light Studio?
Title: Re: Porsche 921 - WIP
Post by: yotah1 on June 10, 2013, 11:12:48 AM
Ryno : no my sketches weren't posted on SimKom, I never post on that website. Besides, the design was done about 2 weeks ago, so i doubt you saw them somewhere before...

itc : the HDRI I used for the last 2 renders is from Dosch Design HDRI Car Backgrounds. The studio renders were done with one of the studio HDR included in KeyShot.

Post by: itc on June 10, 2013, 02:00:22 PM
Thanks for the quick reply.
I was talking about the studio shots.
You said it was one of the default hdris in keyshot.
Would you be able to tell me which one it is?
If you are too busy it's okay.
I will figure out :)
btw, are you using the default material as it is or are you changing the paint flake size and other parameters?
Thank your for your time!
Title: Re: Porsche 921 - WIP
Post by: yotah1 on June 10, 2013, 03:57:17 PM
I tweak about 90% of the materials i use, mostly for the textures and the reflections when it is a paint (metal flakes are way too important for my taste on the base setup).

The HDR, i think it's studio008 or something. White-ish floor, dark ceiling with several neon-like shapes in it. It's one of the coolest for my taste as the lines in the ceiling help describw the shapes of the volumes.

I have more renders coming as i've now built a showroom around the car but they will only be available in mid-July as they are for a magasine.

That's right..i was one asked him because .didn't do with Catia.....
Well is simple because i asked...Alias is a powerfull software like Ug or Catia..(and price is not low...sure is not for a private use), ..and i thought was strange to use a complicate software as Alias, for a project that is not finalized to a real production..
Alias is able to works with Class A Surface..and was born for automotive sector, to make surface that will need to make a real car..so is not like 3ds Max... ;D..i was just curious...everyone uses the more confortable software..as i'm using Nx..starting to works on past century with Computervision and silicon graphics...then Pro-E...then Catia..then Alias and Ideas..then Ug Nx..etc etc.. ;)
So who remember Computervision????? the most complicate software i have never used on my life
Title: Re: Porsche 921 - WIP
Post by: edwardo on June 11, 2013, 03:16:28 PM
Oh hell, i remember computervision, in fact that and wildfire 1-3 still cause me post traumatic stress syndrome! Hate them!!! in fact i hate all parametric software (although I'v never tried Siemens NX). Unless your an engineer or work in an environment where tiny, iterative changes constantly need made, or huge assemblies then surfacing is the way forward! So rhino or alias do it for me.

ARRRRGGGG, why did you have to remind me of PTC's devilware?  :-\

I got some news back from the Porsche design director : they loved the project, everybody loved it, but right now VW has locked all hiring possibilities throughout the group, so it means no job until at least early 2014.

It's ok, as long as they loved it, that's what I wanted.
Now off to the future job in Italy at MV, it's going to be nice to do some bikes for a while.

Post by: Speedster on June 13, 2013, 05:55:08 AM
Sorry to hear about Porsche, but it's their loss, even temporarily.  With you on board they wouldn't need a hiring freeze!  Best of luck at MV, and man, if you do for bikes what you've done here- well, we know the answer!

Another render of the 921 done today (just a quick one hour shot for the body, and 30 min for the rims).

For the previous one in the sunset, I can't remember, it's from on HDRI package I got online.

Design reminds a little of the Mazda RX7 too - especially the fender line to DLO and the door/B pillar area.
I really like the high lights your getting in the render - may I ask what environment your using?
