holograms

two tests how the scanner behaves with holograms

hahah that is way cool! never imagined a hologram was "capturable" like that. would it work with a cd too? and f.e. chromatic glass? always hard to get those effects..

[Ivaylo Katev]

yes of course, it will work with cd and any other magic-like materials

[super gnu]

brilliant. id still like to see a tray of desert sand top work!

[vlado]

Heh, I didn't expect it to work so well

That's pretty stinking cool!

wrt the holograms, do you just get the colour shifting, or do you also get the parallax motion/3d effect when the viewpoint moves?

You mean how we do this internally? We have a scanning device that ,makes about 5000 photos of 2x2 cm square of the physical sample under different view and lighting angles , but in reasonable time (about a minute or two), then we combine them in a vrscan material, that is from 10MB to 200MB wide, depending on the features. If the physical sample is bigger than 2x2 cm, we put it afterward in a second device, that "enlarges" the small scanned sample to the full sized sample, without significant increase of the file size (proportional to the surface is not acceptable), for example if the 2x2 material is 200MB enlarged to 20x20cm it becomes 220MB, only 10% growth for 100 times bigger surface. These holograms are not using this stage, because they are small in size, but the most samples require it. The second phase makes possible to render without tilling, this is very important for materials like leather, wood, fabric etc...This is the kitchen process briefly, as user you have just to load the vrscan material and to assign it, this is all. Of course there are some tweaks, but they are mostly intended to accelerate the GI rendering.

In short - yes, you will get the parallax

perhaps i didn't understand the question correctly, the spheres are used to demonstrate the materials exactly to give different view angles, you can see clearly that the nokia hologram shows paralax in the different part of the sphere, so i decided that the question is not about the presence of the paralax, but about how we achieve it.

the videos dont seem to play for me in chrome, windows. but maybe its just my slow connection?
I see that you scanned different holograms of numbers, are you planning to add a simple hologram without any pattern so it is universally usable?

Hi Manuel,

We could not find any issues with the videos. They are uploaded to Youtube so you generally should not experience any troubles
As to the plane hologram, this is a fantastic idea and we will try to find such a material and update the library with it.

I can confirm,I can't see videos (chrome)
they seem to be upload to Vimeo, no ?

[Ivaylo Katev]

yes, i have the same problem, i think it's vimeo fault, here is the link https://vimeo.com/173726972
