Need for Speed (1) Track Conversion Tool

Postby Nem » Sun Apr 06, 2014 9:44 pm

Hi,
I'm rewriting from scratch a very old project of mine that I've never distributed. I'm developing a tool converts the tracks from the first Need for Speed to Torcs. You can find the tool and some information visiting my site https://sites.google.com/site/2torcs/.
Since Speed Dreams is a fork of Torcs, I'd like to give support for it. I've tried to import a track in Speed Dreams and, after some crashes, I did it. To achieve this result I made, by "hand", some changes in my .XML and .ACC files.
Beside the track is playable in Speed Dreams, there still some problems. The first is that it have the wrong background image (Sky version = 1). If a change to "sky version = 0" the background is ok, but the game crashes after few seconds. The second problem is that the shadow map is wrongly mapped on the road. I think that it depends from "raceline" mapping, seems that for the shadow map the game uses the mapping of the raceline texture. The raceline texture is correctly mapped, so I think that Speed Dreams allow only 1 texture mapping coordinates.
Any ideas? There is manual or a tutorial for track editing?

I read somewhere that Speed Dreams use a different set of values for road parameters (Friction, rolling resistance, ...). Is that true? Where I can find this information?

In the folder of the Espie track I found 2 more shadow textures, shadow3 and shadow4, but this files are not used by the track files .acc, .xml. Are they needed by the cars?

Any help will be appreciated.

Thank You in advance

Regards

Raul

P.S. If You are wondering why I'm doing this, it's only for my own fun. I aware of the fact that the results will be not comparable to modern Speed Dreams tracks.

Thanks menycsab. I saw only yesterday your reply. If You still interested, I will release a new version in the next days.

Thanks!

Is there a program like this which can convert the VDrift tracks for TORCS/Speed Dreams? VDrift has many good tracks!

It would be nice if there were other tools like mine that convert tracks from other games to Torcs/SD. I hope that someone will start one in a near future.
My tool is almost finished, only some tuning to do and, with a very low priority, some scenery enhancements.
My future plans are to convert another old game, I'm looking for file formats.
Vdift it's a very good game with great tracks, maybe someone else can start a convertion project for it.

The problem with converting tracks from other games is that they have variances in track width in a lot of cases, which SD doesn't support directly. You could port the track models, but you'd need to carefully fit the track XML data and modify the 3D model to fit the track data. At that point, it's probably easier to just make the tracks from scratch.

You're right, once created a 3d road model compliant to TORCS/SD xml format, the original 3D scenery have to be stretched/deformed/modified in order to obtain the final track. In the whole process there are often track oriented customization that prevent this kind of tools to be used in the same way for each track.

Well hopefully by June 2016 I will have completed a full rewrite of speed dreams using ioquake3 as the render backend allowing bsp map like boundary definitions to allow for varying widths, and I do plan on tracks from NFS2/3/4 being included re-rendered in OpenGL ( updating ioquake3 to use OpenGL 3.x by default with fallbacks to OpenGL 1.5(min) and support for OpenGL4.x capable GPUs). Just thought I would throw that out there. Any kind of support is greatly appreciated. But yeah I have played torcs and speed dreams for the last 4 years and got hooked on these linux native race games but always was hoping for better framerates and better visuals, not possible using the current render engine, so I have thought about it for the last three years and decided that since I helped delvelope the python language and Quake3Arena"s graphics system, why not refresh myself on the code and developement of those powerhouses and integrate them into torcs and speed dreams for a more playable final result with higher frame rates while acheiving superior graphics, higher polycounts, true emissive surfaces for blake disk glow, brake lights, reverse lights, and projecting headlights (simple volumetric and lightmap emissive texture using quake3's shader system but updated) Also plan on upgradeable vehicles with parts system hybrid of the new 3d nitro nation and race rivals for android. And an official android port of torcs/speed-dreams.
