Universal 3D File Format In The Works
telstar writes "The Register is reporting that more than 30 companies are working together to define a new file format intended to serve as a universal 3D file format. The new file format will be named the 'Universal 3D Format', or U3D. According to the article, they hope to make the new format as standard as MP3 has become for audio, and JPEG has become for 2D images. Interesting that they would choose two lossy media formats as models for comparison."
The lossiness of MP3 and JPEG was only relevant because it allowed the actual files to become small enough to transmit over slow connections and fit on small hard drives. Additionally, while they may be lossy, the "lost" information goes completely unnoticed by the end-user, 99.99% of the time. If they come up with a convenient way of storing 3D information that is "lossy" but doesn't lose anything that will be missed, then more power to them.
Additionally, the demand for small files, and therefore for MP3 and JPEG, draws on preexisting "content" sets that are enormous; all the audio data ever recorded (including in analog media), and all the static, 2D visual data ever recorded (including photos, texts, drawings, etc). By comparison, there are currently relatively few recordings of true 3D data; and the present uses of that recorded data are so specialized that a general file format would probably be insufficient anyway.
So the day that Wal-mart starts selling digital cameras that laser-scan the whole room and render a complete 3D model, and the day they start selling holographic projectors for those 3D models, at prices that are reasonable for personal use, then there will be a market for a generic 3D file format.
