I currently have an application that uses openGL in order to render a 3d model of a car. I would like to change the car models but I have no clue what format my application uses. The current format of the working 3d model is directory that holds one xml file, 3 .tga files, and arround 40 .dat files. I am a backend software developper and I have never done any 3d modeling. I would be very gratefull if anyone could enlight me on what format this is and how I could export a blender format into this format.
It could be the X3D format, but without more information I couldn't be sure. You could try reading A comparison of 3D file formats. If you're in a unix/linux environment you could try file. file(1) - Linux man page. Finally you could trade a game/engine data extraction tool Game Extractor Game Extractor(might be the same software) Extraction tools
