Is fire realistic now?
Image from DC3.0. Light environment is HDRI panorama from real Park

very cool serg, the fire does look more realistic now. the diamond looks rather dark compared to what i usally see in real life but maybe it''s just my monitor (or my always bright and clear sunny skies

). very well done. are there any more new features you could share with us?

 

[denverappraiser]

Cool!

Is this now the current version? If not, do you have an estimated release date?

Agreed.

Also, what's the second picture (oops, I think you told us that above).

Re:the diamond looks rather dark compared to what i usally see in real life but maybe it''s just my monitor (or my always bright and clear sunny skies

Good but very difficult question. I will check different exposition( adaptation level) and viewer size.

Re: If not, do you have an estimated release date?

End of September 2006

Re: are there any more new features you could share with us?

Other features will available in DC 2.9 in End of August-beginning of September

The fire and the image are attractive. I don''t remember seeing a diamond look this way in real life, but maybe I never looked at one in such an environment.

What does this image mean to YOU?
Does it show this diamond to be highly, moderate or low in fire?
Is this an image that would be used to analyze the performance of a diamond?
Is something beyond a pretty pictiure being shown?

Pretty pictures may help to sell diamonds that are distant such as on the Internet. Is this the purpose or is there a more complex purpose?

Thanks for the info.....

Good questions Dave I was going to ask something similar.

 

[Serg]

Dave,
You are asking about business tasks.
My current task is from other field. I want create correct TECHNICAL INSTRUMENT ( Virtual Photocamera for diamonds)
In other words I want create electronic micrometer with accuracy 1 micron. For what tasks will you and other ( and I ) use this micrometer does not matter for me now(yet).

Serg was at the AGS Conclave, where he showed a group of us a preview of what he had developed. I am not sure if we saw the completely finished version, or if he has added more to it than the initial images we saw.

On his computer screen, he had a photograph of a mountain scene, and an emerald cut diamond.

The diamond could be tilted, turned and otherwise "adjusted" and it reflected the landscape of the mountains that were photographed around it. It showed the brilliance and dispersion that the eye would most like see when a diamond in a incredibly realistic way.

Quite a fascinating change from what we currently have.

Where this probably has some usefulness is that someone can photograph a particular environment ( room, outside, office etc) then import a scan of a diamond into it, and it will show how that diamond will appear to the eye.

I may not be right, but if a consumer has a photograph of a room environment, they can import a diamond into it, and see how it will look in that environment.

It was very obvious that Serg has put in a tremendous amount of work into this.

What I''m not sure about is how the photo is made. It appears to be a 360 degree photo, so I don''t know if you need a camera capable of that, or whether you import several still photos or if the photos has to be a video one.

However, it is totally awesome, to see the change in the appearance of the diamond when it is turned.

Yes you are right. This image has too much green. real diamond has less green. The reason : We use only 3 color channel ( RGB) in DC3.0/
Current DC has at least 20 color channels

Rockdoc,


We use Spherical Map High Dynamic Range Images - or HDRI.

See for example:

Those are really neat sites..... the advancing technology is really quite astounding.


What we were privileged to see in Orlando was really incredible. Figuring out applications to use these for will be very interesting as they develop.

Thanks for those sites, I looked and they are really incredible with what they offer ( not that I understand it all, but seeing the photo images the spherical cams have done is just mind boggling to be able to photograph such images with one shot.)

Sergey that stone is 21ct? Why so big?

Will it be possible to use an incomplete photo? Eg take a photo with a normal camera facing the same direction as the diamond that might only include 1/4 of the panorama?

You have already told me it will be possible to use stitched photo''s that we can all do with common camera software. I presume we would need to use the camera on a fixed exposure setting?

Bigger diamond has better fire.

May be. We will try do it.

You need do several photos with diffirent exposition. then you need convert these pictures to HDRI panorame by special software

Sweet developments Serg.

Not to mention the updates to the Helium Reports you recently made me aware of. Should have those installed today.

Regarding the darker appearance ... if this is mimicing the appearance and the diamond in your example has access to direct sunlight, strong direct lighting (such as outside on a sunny day) will generally cause the body of the diamond to appear darker (such as shown in Sergey''s graphic) yet the flashes of light and fire will be more intense. Kind of a trade off. In diffuse lighting the body takes on what appears to be a different color (not dark but light in excellent performaing stones). Viewing the graphic reminds of of direct lighting environments and considering the picture is outside would I be wrong in assuming that it is mimicing a direct light view Serg?

I recently completed a video demonstrating this. Perhaps Leo can post it for me.

Regarding the present views in DiamCalc, I find the that the office lighting view mimics best the appearance of brightness, particularly outside in shaded sunlight. I have some interesting comparison photography to the images generated within the software you might find interesting.

Kind Regards,

It would work better with round well cut stones becuse they gather most of their light from a small amount of arear directly above the stone.


It would still be a better basis for grading information then the very small lighting area used in GIA''s Diamond Dock as discussed here https://www.pricescope.com/community/threads/gia-diamond-dock-simple-summary.42538/

For instnace this photo taken of me and the inside of a Diamond Dock was taken from a stiched photo of 3 shots. The camera was where the diamond would sit and does not have a wide angle lens.

So perhaps a normal wide angle lens (especially on a square format camera) would capture most of the important light soruces?
