How do I create a hologram?

[Lindal Kidd]

Are you sure they are one prim objects?  You can get an illusion of a three dimensional object from two dimensional prims xy intersecting two or three of them in an X shape.  A lot of plants are made this way.

Or possibly the object you want is a sculpty?

EDIT:  Wow, that's an interesting effect...I hadn't seen it before.  I've no idea how it's done.

Yes it was a 1 prim object. And it looked the same at all angles. Here is the rose vase I bought. https://marketplace.secondlife.com/p/Red-Roses-in-Red-Vase-1-Prim-Hologram-Giftable/4450884 It is not a sculpty, but a hologram.

Well, i's not really a hologram, but that's a clever way to market it. We used to have to make those as Val says by intersecting two or three thin prims. You can do much better with sculpties, and now with mesh, which allows you to use up to 8 distinct faces. The "holographic" effect in all cases takes advantage of the alpha sorting that drives many people in SL nuts. Done well, though, it produces a very convincing effect.

I believe it uses the particle properties of a prim. Very well done in fact.

[Lindal Kidd]

This seems different, Rolig. The effect is of a two dimensional image that turns so that it is always facing you, no matter what angle it's viewed from...very odd, if you you try looking at it from, say, the top. The object itself is a a simple, transparent, truncated cone, but you don't see that. The image spreads beyond the edges of the prim.

Ah, so this IS a particle effect, then. Interesting. I'll have to see if I can do that.
