[GRASS-user] r3.out.vtk for paraview

[Francois Chartier]

I created 3 rgb maps using the same DEM file. should i be using 3 different
Dem or raster files instead?
Wouldnt it make more sense to be using RGB files developped based on the 3d
raster (even if that option doesnt exist).

You need to specify three maps:

rgbmaps=name[,name,...]
    Three (R,G,B) 3D raster maps to create RGB values
[redmap,greenmap,bluemap]

Indeed, the [,name,...] is confusing here!
