Hi Johny
And why not a geometry approach?
You can totally use 3d models, but that might induce z-fighting, sorting
problems etc. Another option is of course using a world-space spanning
texture per object-instance and managing drawing to this texture at the
right spots. This isn't very memory friendly however.
It seemed to me, that you have a multipass-shader implementation anyways
so using screen space decals might be the best option. (And I've got
good experiences using it)

Hi Johny,
Here's Johny!
I'd like to know how to pick a 3d point in my model onto which a decal will
nearly wrap itself around to. Am I using the right word here, or does Open
Scene Graph not have this feature? Before I'm rigging my app with a custom
decal, I'd like to know what's available, or what tools I can already work with.
There is no specific API, but you can use projective texturing or
screenspace decals (using FBO and shaders).
Cheers
Sebastian
Thank is great.
