This page on the DGS site (Deutsche Gesellschaft für 
Stereoskopie) is a surprise for me. 
The glossary was printed in the last issue of "Stereoscopy",
the journal of the International Stereoscopic Union.

As you can read in the acknowledgements, among many names 
mine also is mentioned. I indeed have send several comments on 
a preliminary version to Don Wratten, of which a few, but of 
course not all, found their way to the final version.

As a matter of fact, in that preliminary version in the
definition 
of "accommodation-convergence link" was spoken of a link
"which 
has to be broken".  I have commented that it suggested 
violence and damage, and the final "to overcome" is still a
little 
overstated in my opinion, as you might guess from my postings
last week and that I have uploaded the Howard & Rogers figure.

On of my other comments was on publication on the web, but Don 
said that he would leave it to the ISU Committee and the 
editor of "Stereoscopy". Now without public announcement this 
English language glossary suddenly _is_ on the web, on a 
_German_ site, but only in the English language section of 
that site (Germans will never get there :-)). I have written 
before on the German interest in stereo glossaries and 
standard stereo terminology, but this surely is a surprise. 

I have a plain ASCII version of the glossary (38 kB), which I 
of course could upload to the P3D files section, but I should 
like to hear Ray Moxom's, Allan Griffin and Robert Leonard's 
opinion on that first. Is there some sort of copyright?
