3d-visualisation

Hi all,

unfortunately there was no request to my celldriver/24bit-question on
the list.

Is there an other way to do it? I'm just trying to work with vis5d and
have problems with compiling an import filter for grass raster files.
Maybe someone knows a (better/different) solution....

thanks
