Hi there,

I'm trying to use openVDB implemented in Houdini 12.5. But, I can't understand how to use it even after I looked at HDK documentation.

The followings are what I wonder :


1. I can't find how to set density value in a specific grid(vertex). Where is the interface to set density?

2. If there is no way to set density value in a specific grid, are there any ways to convert or add volume container to existing VDB? If so, I can use VDB by adding several volume container.

3. Are there any difference between grid and vertex in documentation?

4. Is it right to use class ‘GU_PrimVDB’ when I want to use VDB?



I know it's very basic question about VDB, so I think it's the best way to understand those question to get examples about VDB. But, I guess it's a little bit hard because it's a brand new.

Thank you for reading my problems. I'll be really happy if you get some answer. I'm looking forward to your reply.
