Hi everybody,
i'm tring to figure out how to previsulize the displacement map directly to geometry. Probably it's a stupid question, but i'm just moving my first steps on houdini.
I really didn't understood how may i take info from a texture(uv, color, res…) to use these i a vop.
Could anybody help me?
Thanks in advance.

one way to do this is:
using displaceAlongNormal in a VOPSOP
as uv coordinates are not accessible as global variables you need to import them. Also they need to be applied to points.

here is a quick example.

Hope this helps.

I got held up in the middle of this, but here's my version. Ever so slightly different from Georg's, but does the same thing.

There's at least one school like the old school!
