try the following:
points=bytarr(nx,ny,nz) ;dimensions of the volume you want to plot in
;your points, maybe (max(x)-min(x))/100. and so on
intensity=200b ;or intensity of each single point
for i=0,n_elements(x)-1 do points(x(i),y(i),z(i))=intensity
common volume_data,a
a=points
slicer
end
the SLICER procedure is very convenient to display in 3d, you can find the
source code in the userlib to modify it for your special application for
instance to use tvrd to get hardcopies
