[GRASS-user] r.to.rast3 - how to display a g3d ?

[MORREALE Jean Roc]

Hi,

I've been trying to use r.to.rast3 with geological surfaces but I've not been able to display the resulting g3d into nviz (grass 6.4rc6 on windows/linux). Here the steps I've made on a simple test case with just 2 layers (top and bottom) created from a 4 points dataset :

g.region vect=point_source at volume res3=50

v.extrude input=point_source at volume output=top0 height=2000
v.extrude input=point_source at volume  output=bottom0 height=0 

v.surf.rst input=top0 at volume layer=0 elev=top0_rst tension=40 dmin=80 dmax=300
v.surf.rst input=bottom0 at volume layer=0 elev=bottom0_rst tension=40 dmin=80 dmax=300

r.to.rast3 --overwrite input=bottom0_rst,top0_rst output=vol3d_01

nviz volume=vol3d_01 at volume

The NVIZ's window is empty, the volume panel is set to isosurface. 

Could someone points me to the step I've missed ?
