Holographic material

Hello

I have to use holographic material, to describe it I will say,
It is a mirror/silver base with light spectrum reflection/diffraction visible on the object edges, and changing when moving the point of view. (cf pictures)
Do you think that it is possible to make this material?

Hello MrC11111,

From the pictures you are sending, it seems to be an iridescent shine, not an hologram.

You can do it adding a Coating on top of your material, and adjust the coating thickness to get the proper color gradient you are after (regarding the thickness of the iridescent coating on that particular cloth).

Said that, an hologram is a completely different thing.

Let me know if this answers your question.

Greetings

Hello Dariolanza

Thank you for your answer, I will try your technique, I hope I will be able to do it, I let you know ;-)

About your remark for "hologram", hologram is a wide technique used on a lot of different manners, and one of them is like the pictures I joined, I let you see « rainbow holograms » section on the wikipedia dedicated link http://en.wikipedia.org/wiki/Holography

It could be done by multi BSDF in different color and anisotrophy ;) Check these examples:
