[GRASSLIST:3070] Grid 3d

[Henning Ries]

Hello

I want to use the Grid 3d modules. But unfortunately I can not find them 
anywhere in the source code distribution of Grass5pre3 (besides s.vol.rst).
Do I have to compile the Grid 3d modules separately? If yes, where can I find 
the code?

Thanks & Regards
Henning
