Hi guys, I wasnt sure were to post this but anyway I was modeling a small city and while I can look at the results in th 3d modeling program I would really like to be able to walk around in this city from the first person perspective. Basically all the program would need to do is render a 3ds file, do collision detection and a bonus would be if one could walk up stairs, i.e. the progra checks the height of polygons to determine whether they block the path or are steps. Its really a simple program and I could create it myself but since Ive never used the 3ds file format I thought it couldnt hurt to check whether this already exists. Any ideas? -CProgrammer

Probably not what you want, but couldn't you simply load your 3ds model as a mesh into an existing first person game? Using Unreal3 (unreal editor) or HL2 (source engine) should do it.
