Hi Ying,
yes, that is totally the right place, as long as your number of input
vertices matches the number of output vertices.
Vertex shaders can also sample textures.

Hi Robert,
Yes, I want to convert a vertex position to a new vertex position. To do so,
should I use a vertex shader?
Thanks,
Ying

Hi Robert,
I'm trying to implement a distortion function, and the distortion should be
worked in 3D. By using the 2D texture only allows me to achieve the distortion
in 2D. That's why I'm trying to use a 3D texture.
If this wouldn't work, would you please give me some suggestions?
I started to learn osg not so long ago. I'm sorry if my question is a little
stupid. :))
I don't think the issue is an OSG one, but the basic concepts in play.
I can't work out how your approach is supposed to work.
My best guess to what distortion using a 3D texture would be that you
want to convert a vertex position to a new vertex position in the
vertex shader using a 3D texture. If it isn't this I haven't got a
clue.
Robert.
