this is OSG.

i think it is the complete suite.

thanks to all!
i will try the 30days version of OSG, which seems to be what i need.
i don't like the idea of the viewer, because anyone will be than able to install the complete version and modify the model.

thanks again,
ale

hallo!
is it possible to share a skup model with someone who do not have skup, without giving him the model?!?
i mean...i would like to send a model, but i do not want that who will receive it can modify it...is it possible?
is there the way to export the model and making it read-only?

thank you,
ale
