The following are largely my personal collection of references to a range of data formats in use in the computer industry, some are just copies of manuals and documentation, others are my own investigations and associated reports. The largest section is on 3D geometric formats, but there are also notes on image formats, conventions and other miscellaneous data representation topics.
Standards are good, lets have lots of them. Anon
Geometric data formats
Outside of a dog, a book is man's best friend. Inside a dog, it's too dark to read. Groucho Marx
Image formats
I can picture in my mind a world without war, a world without hate. And I can picture us attacking that world because they'd never expect it. Jack Handey
Other data formats
Audio formats: AIFF, AU (SUn), WAVE. Descriptions of the minimal requirements necessary to create standard audio data files.
Stereo Pair Image File Format. Format for defining stereo pair attributes proposed by VRex Inc and the interleaved format.
Format for describing warp meshes for unusual projection environments.
Various EEG file formats and Conventions. Includes continuous (cnt) and average (avg) EEG format from neuroscan, EEG format as used at Westmead Hospital (Sydney), and Pauls ad-hoc ascii format for EEG.
Convention for grid data storage.
Six is a number perfect in itself, and not because God created the world in six days; rather the contrary is true. God created the world in six days because this number is perfect, and it would remain perfect, even if the work of the six days did not exist. St Augustine
