I'm developing a website that can display 3D models of motorbike. I haven't decided on which tool to use yet but it seems most of them support X3D and VRML files. So I'm searching for already-made models in either format but got no result so far, anyone know where I can find one? Thank you.
Turbosquid.com has quite a lot of free mesh models of moterbikes, you can browse them here. If they are not available in your desired formats, you can always download them and convert them through one of many converters available out there, such as MeshLab, which supports both VRML and X3D, among many other formats.
