   Object import
  I'm turning a game I created (done mostly under the console) into 3d. I understand what I need to do to make this but the problem is what file format should I use?I plan to support of course the basic import of the object uv's, texcoords, tex file etc but I need a format that uses vertex animation (not trying to do something more complicated like skinning/bones atm).I considered the directx format or would it be better to use a different one. I making it because I'm using opengl.   
  I dont know what format you should use but I think if you are using OpenGL dont use .x files because it would break one reason why you would want to use OpenGL in the first place (multiplatform).
