This may seem like a pretty strange question, but has anyone created their own file format for their 3D engine? I am just wondering where I can find a good tutorial or book for attempting to create your own file format for loading things into your own 3D engine such as 3D models from modelers and animation software. I am also wondering if anyone can think of any good 3D modelers and animation software that a beginner should purchase. I was thinking of Maxon''s Cinima 4D Go, or Caligari''s Truespace 3. Any help would be very appritiated. Thanks Edem Attiogbe
