A seminal early text on lenticular and holographic imaging, Takanori Okoshi's -Three-Dimensional Imaging Techniques- provides analysis and insights into the fundamentals of 3-D perception and the creation of 3-D imagery as well as a history of its technological development.
I noted three distinct points of this book:
first: the categorization of 3D imaging/display in a nice and easy to read table - in Ch.1 (but this is now quite obsolete).
second: the brief, but very clear, explanation of ten depth cues: six6 pictorial/psychological and four physiological cues in Ch.2- even my wife who has no electrical/electronic background (but in psychology) can clearly understand this chapter except for maths (not only understand but she also surprised to see the author,an electrical engineering professor, could compile the psychological aspect of viewing).
third: the statement in the chapter of holography (Ch.7?) that up to now no display can provide accomodation cue expect hologram. this is a truly 'blitzkrieg' in my knowledge: for years my understanding on hologram was it was the true 3D display as it's capable to provide depth cue from motion parallax. again now we have seen full view 360 degree webcams everywhere (albeit its distortion) artifcially presenting look around effect, yet our spatial perception is barely provoked... Prof.Okoshi's statement for me sounds like a 'forecast' that one day efforts to build 3D displays will fluorish with various methods in attempt to create the whole 4 physiological depth cues. but only a few can hardly provide accomodation cue (or it can be created but at the expense of very costly supporting electronics). the exception, as he stated, is holographic based displays.
Definitely the major shortcoming of the book is the examples presented in the technology of possibly 70s-mid 80s. All has been out-of-date, it needs to be rewritten. Yet the basic concept understanding of 3D display of this book can be retained.
The author was Japanese, even the original manuscript was in Japanese. No wonder the translation is very plain, but it is very good for scientific/engineering text, especially for me which english is not my first language, since very unlikely misntepration takes place in reading the text. I contacted the publisher inquiring the availability of the text and they responded the book has been declared out of print since the beginning of 90s.
(btw: joel, if not mistaken you're a former member of spatial imaging group media lab weren't you?interested to update the book?i'll be happy to support...:)
Its out of date, has some incredibly bad math notation, and is not particularly accessible to the non-specialist. Its also invaluable as a resource to anyone working in the field. Sigh.
I wish someone would update this book and put out another edition -
