Quoting RocDoc:
"Sergey showed us some very interesting stuff he is planning on his portable laptop computer that show the appearance of diamonds in various environments. The work he put into this is simply amazing. The detail of how the diamond appears is just short of spectacular. You take an image of where the diamond will be, input the type and proportion file, and it produces how the diamond will look in the image you input. He had a scene of daylight in a photos where there was intense daylight in an area surrounded with mountains, and you could see just how the diamond would look, with amazing detail, even with the reflection of the surrounding mountains reflected in the table of the diamond. Sergey really is an incredibly nice guy with lots of brilliant ideas to improve and develop some amazing changes to what we already have available to us. It's almost scary to think what incredible tools we'll have five years from now."
I hope that credit was given to Anton Vasiliev who presented this in an article of the Russian Gemological Bulletin No3(6), 2002. English translation was rejected by British Gemmological Journal in March 2004, although it was the sequel to an earlier article they published. I have shown some examples in Garrys thread "Simple Science", which I repeat here.
Here is the environment of one stone. The white dots are locations of light sources that will travel to the viewer's eye; the color at that dot will be seen on the gem's surface, face-up. The black object is the viewer's body and head.

thanks, RockDoc for pictures and reporting

And here is what the stone looks like, with viewer's head only, at left, and with body also, at right. The stone can be moved or its cut parameters changed as yo are viewing it, and you can see the effects.
This software has been available for years from Anton and an English tutorial was added in June 2004 (it is under 'Help' on menu bar). AGS has provided this software free on their discs for at least a year under the unfortunate title 'What to do if you cannot open these files). There are also 6 Tips & 6 Newsletters (e-mail) to clarify certain points or show tricks you can do.
Anton or I can send you the software, Tips, & Newsletters directly, if you wish; we are at ...

Actually Bruce, it was more complex than what you show. It was a rendering of the diamond responding to the global envirionment, as if the diamond were in your picture, and at blazing speeds (using a dual core processor laptop).

The global picture was used as the source, so one could take picture(s) of any complex lighting envirionment(s) and present an accurate visualization and/or metric of its response to that envirionment. Will greatly simplify the math of defining the envirionment for ray trace modeling and analyses..

Marty:
I think you wrote before seeing the second illustration, above. There is further explanation/illustration in Garry''s thread.

Hi Bruce


What Sergey was able to show us was a lot more detailed visually than what you''ve posted above.

You did see the "scene" like the first image you posted, but with a very realistic appearance of the environment of the diamond it self, which could also be moved and rotated showing the result appearance of the diamond itself which also including surface reflections of the apparent environment.

Sergey had even bought a special laptop computer with dual core processor to show us the results, as Marty mentioned. It was really stunning, and even Marty was greatly surprised and impressed, which is really hard to do.

Far more extensive an appearance than just viewer or body obstruction image as your second image showed.

Think you have to see it in person to really appreciate the depth and detail of what he''s accomplished.

I think Bruce''s main point is that Anton developed the idea first.

HDRI Had been invented in 1998-1999.
But It is not enough for correct modeling Fire and Scintillations. Try see Fire in Anton software. Anton software is nice product but for color stones only. Octonus and Anton are working for different niche. Our calculation core is quite different from Anton core.
