Todd's sim screenshots

Hi everybody, A couple of you wanted to see some screenshots from my race sim project. The base OpenGL graphics engine only took about 3 days to get and running, then longer of course to decide on textures and make a couple cars, get the physics engine plugged in, etc.. Right now, this is just what I use to develop the physics for an RC car racing game that'll be a free download for everybody (whenever we finish ;-)) After that, work will continue on this. Perhaps I can "borrow" some of Ruud's cars! http://performancesimulations.com/scnshot2.htm FWIW, Todd Wasson --- Performance Simulations Drag Racing and Top Speed Prediction Software http://PerformanceSimulations.Com

Pretty cool... Wish I had it in me to do somethin' like that! Warlock! "J. Todd Wasson" wrote:

Love the detailed instrumentation! Does the odometer really work? :-P Keep up the good work. -- Fester

Tis looking nice :) How do you mean 'plugged-in', have you purchased a 3rd-party physics engine? Just curious. (btw looks like your tex coords are in the wrong order on the second tri of each track section) "J.

I've tried it every which way and it always seems to have a seam (seams to have a seem?) Part of my difficulty is I've made a little track editor that generates all the triangles automatically based on inputs like track width and corner radius, etc.. So it's tricky making it work the same way as the graphics part. Any suggestions? Is it probably just a couple numbers flipped around somewhere?

Thanks, Fester :-) No, the odometer was disconnected to keep the value of the simulated cars from depreciating as the race continues. Don't tell anyone :-) Todd Wasson --- Performance Simulations Drag Racing and Top Speed Prediction Software http://PerformanceSimulations.Com

That's not from your Ferrari, really, honest 0;-) I put a picture of a Hooter's girl on the hood once.

> A couple of you wanted to see some screenshots from my race sim project. I have a question about the suspension geometry which is clearly visible in some of the shots, how would you be calculating your wishbones? Are you using constraints or some other ( string / mirrors maybe :-) ) method? Colin P.s. 'Tis looking good, and I say this from the point of view that the physics are clearly visible in the shots ( if that is possible :-) )

Nice work Todd, I'm looking forward to testing your first beta release :0) As for your texture problem, if you assume the texture U axis is "the width of the road" and the V axis is "the road centreline" then I think you have the U coords the wrong way around for the "second" triangle in each triangle pair.... Cheers Jim

Hmm I take that back, looking at the "F1 doughnut" picture it's more complicated than that. I suggest you paste writing over your texture and then fiddle with your track generator code until the writing lines up as it's supposed to. Hope that helps Jim

Ok, thanks. I didn't spend too much time on that because I really didn't know if the textures I have would ever show up seemless like they do in other sims. I'm new to this 3-D stuff :-) Todd Wasson --- Performance Simulations Drag Racing and Top Speed Prediction Software http://PerformanceSimulations.Com

It's a really simple model right now, but don't think most folks could tell by the way it drives.
