Hi All... I work for a company that make 3D Games for mibile devices... We´re now working on a car drag game ( no curves, the car runs straith from the beggining to the end... but there is some terrain elevations, but no curves ). We´ve already modelled the cars, the accessories, everything is pretty well. I´m the person who will build the 3D world. Since mobile devices doesn´t have too much memory ( nor processor ) we have to be very economic. I think that building the entire world will be so hard for the mibile to load , and will be big in size. And we want to build more than one scene, we need at least 3 of them. Is there any other sugestion to build the 3D world. I was thinking about making pieces ( Like LEGO ) and then tell to the development team how to position these pieces in the game. Something like i build a rectangle with 10m and to make a 100m road the development team just use 10 pieces of that. I model 5 houses and the dev team place those houses at the place i tell them. It´s not so hard to do 'cos i can export my scene in .ASE format and all information about position, rotation is there. The dev team can make a parser to read this file and then automatically load all the objects ( and how many instances of any object needed ). Well.... the question is: How to build a 3D world for mobile games without modelling the entire world. Well.. i hope i was clear enough....... Cheers..

You could try making a very detailed 2d backround, while only using actual 3d polygons for the part that you drive on.

For the track you can use your method easily. How you create that list of pieces is totally up to you: you can either use a heightmap and create a tool that places the pieces according to it, or you can define a math function and generate the level at load-time. You can place the props on the side of the road like this too.

However, depending on your target phones and size of files, the math function way and generated level could be overkill. However, a n-gage would handle both these methods just fine.

You could also use sprites for the objects in the 3d world, sort of like in Duke Nukem 3D. Trees, people, rocks, signs, etc.. hell, even if you were to build a house, you could put two sprites at a corner since the player will only see the front and sides of the house (never the back two sides)
