How do you add extra front wheels to "*.car" file?

[Geo3]

Needing a little advice on how to add extra front wheels to a model, using the "*car" file. Looking at a 70s Tyrell P34 6-wheeler idea.

[joevenzon]

VDrift only supports 4 wheels -- it's hard-coded into the physics engine so it'd be tough to change. Interesting idea, though, I hadn't heard of that 6-wheeled F1 car before.

Pity, but thanks for response.

Here's a link to some info on the Tyrell 6-wheeler :

That is a very interesting car. In order to properly model it, VDrift would have to model the complex custom front suspension which allowed all four front wheels to steer. Unless there is some technical data available about the car, it would be nearly impossible for someone programming VDrift to guess how it should be modeled.

Trying to get some steering and suspension details on the P34. Check out those links :

I have managed to convert a P34 from "Racer" files and have it running in "Vdrift", but with only one set of front wheels.

I have found the following :

Engine: Ford Cosworth DFV, 3-;itre, 465 bhp
Gearbox: Hewland FG400
Fuel/tanks: 42 imp. gallons
Wheels: Front: Twin wheels. 10" dia. 9" wide.
Rear: 13" dia. 18" wide.
Tyres: Goodyear (special fronts with 16" OD)
Suspension: Front: Twin double wishbones with outboard coils.
Rear: Parallel lower links, single top link, twin radius rods, outboard coils.
Steering: Single rack with slave link to each axle.
Weight: 575 kgs.
Top speed: 175 mph.

Note steering (highlighted above), is directly linked from front pair to next pair, so reacts in identical fashion. Could it not be possible to duplicate a normal front layout but moved rearwards and in "car" file named "wheel-FR-2" and "wheel-FL-2" to denote different position. In my vdrift model, I have place front wheels well forward, hoping to be able to add the rear set of front wheels later......

I'll try to upload my P34 conversion somewhere...Geo.

I have sent an email with my P34 zip file attachment to :

admin@vdrift.net

Hope this works!

[joevenzon]

I don't think it worked. I'm not sure where that e-mail points but it didn't get to me. Can you upload it somewhere?

[Geo3]

I have uploaded Tyrell P34 car to my web site :

http://www3.sympatico.ca/gmacgruer/Index.html

It is near top of main page under "Vdrift Tyrell P34 Car Download", and is in a small zip file.

OK cool, I added it to the SVN data repository. Do you have a sourceforge account? If so I can add you to the SVN data repo so you can update the files directly, etc.

[Geo3]

Yes, I have created a Sourceforge Account, and I would be happy for you to add me to the SVN data repo.

[joevenzon]

What's your username? Geo3? Just want to be sure....

[Geo3]

No, for Sourceforge Account, I had to use "geo53" as my username.

[joevenzon]

OK, you've been added!

[Geo3]

Many thanks...Geo.
