Grand Prix Legends Replay Project

For the last days I've been studying how hard it would be to build an open source GPL replay file player. I've made some progress (and unfortunately there is still quite a much work to do), and so I decided to release current sources for everybody to look and try. The diary (and obligatory screen shots) for the project can be found in http://gplreplay.sourceforge.net (unfortunately the older parts are written in the most famous language in the world (=finnish), but you do not need to understand it, just browse through the pictures :) From there, you'll find the link for the main site where all the goodies lie. There are many known problems, some are generated by different OpenGL-variants and I'm not John Carmack, so help would be appreciated, especially on the Voodoo3-area. And if you got some neat OpenGL-accelerated Unix-box (SGI, Sun, anything), please join to the project, it would be way cool to see GPL replays on those machines.

This looks really promising! With this replay tool, you would be able to change the cam angles to any point when watching a replay? I hope someone with the necessary skills can finish this tool.... Jack Rambo maybe? <G> Andre On Tue, 11 Jan 2000 02:03:49 +0200, "Timo Kujala"

Although I don't understand a single word there, I'm assuming this thing is an extra application for viewing the replay out side of GPL? Another wards, Someone who never heard of GPL can download a replay and this application and watch the replay (no GPL on the HDD)? *If* that was the case, This application would be widely used as not only an introduction to GPL, but also could be used as a promotion for a driver and or team:) -- ========================================= Mike Barlow of Barlow Racing? ========================================= http://members.xoom.com/BarlowRacing/ Racing online with the help of......

And it would make an awesome screen saver. A great way to promote GPL to the masses. -- Don Scurlock Vancouver,B.C.

What advantage would this approuch have over creating .mpg(s) from GPL replay files? There already is program called something like GPL MovieStudio that makes frame images from the replay clip and generates an .mpg. Marty

If I could read the page I'd probably understand what it is that he's trying to build. If it is what I thought it might be, then the advantage is overly obvious. No conversion needed and I believe the replay files are smaller then mpg. But again, without being able to translate it... I don't know what he's building. -- ========================================= Mike Barlow of Barlow Racing? ========================================= http://members.xoom.com/BarlowRacing/ Racing online with the help of......

Yes....MUCH smaller, judging from my (not so big) experience with them so far. -- Robert S?derberg If replying by mail,remove the word INGENSPAM from the adress.

Since Tiku himself hasn't responded, I might as well. Replay Player will work as a means to view a GPL replay file. GPL Movie Studio was also developed by Timo Kujala. But since creating mpeg files is time-consuming, troublesome and the files are huge compared to gpl replay files Timo is trying to develope Replay Viewer. Replay Viewer will require GPL to be installed on the viewer's machine! It uses GPL's *.dat files for tracks, cars, textures etc. It won't work on a machine without GPL. Please note that RV might never be completed, although I fully believe Tiku's capabilities to finish it. Especially if he gets help from any of you guys! Hena

Stephen

It would be very nice if we could position the camera anywhere during a replay and making fly-by cams... Andre

well, It's not completely what I thought it was then. Bummer. But the concept sounds interesting! If all the x.dat files could be squashed down to the minimum and sent along with that RV application.. then maybe, possibly... it could be used as a stand alone application. Just thinking out loud.

Again this is not Tiku answering, but.. the code is hopefully going to be portable, so that you could run it on any unix and watch replays anywhere. You'd just need to copy those required files from GPL to the new machine (stuff like tracks and cars etc). -Juha --

Wouldnt a working trackeditor be 100.000 times more usefull and worth the energy?

No conversion needed, smaller files, captions for speed and times etc. and mostly - Camera angles. Slot > What advantage would this approuch have over creating .mpg(s) from GPL replay > files? > There already is program called something like GPL MovieStudio that makes frame

I don't think so ... I'm pretty sure the tracks, textures, cars, everything stored inside .dat files are copyrighted stuff and can't just be distributed around. Hena

ok then, how about giving the code to papyrus and having them distribute it? Or (if it's possible) sell it to papyrus. If there was a way to make this a stand alone application, the uses are almost endless.
