I have done this: I extracted each slice of data from the 3D matrix (that is
each slice is a 2D array and all such slices combined to give a 3D matrix). Then
I output each slice of data as a gray level picture and converted all of those
images into TGA format. Next, I combined all my tga images into a .df3 file
format and rendered it with following code:

global_settings { assumed_gamma 1 }
background { rgb 1 }
camera {direction z*8 location <0,0,-10>}
light_source { <20,40,10>, 1 }

sphere // transparent sphere containing media
{ 0,1 pigment { rgbt 1 } hollow
interior
{ media
{ absorption 5
density
{ density_file df3 "a1.df3" interpolate 1
   color_map{ [0 rgb 0]
     [0.4 rgb <1,0,0>]
     [0.8 rgb <1,1,0>]
     [1 rgb 1]
   } }}}}

But the result showed a very strange shape. I changed the camera location, still
no smoke shape displayed. I really have no idea what's wrong with that. The TGA
image seems correct. I attached one of the TGA images and two images of result
with different camera location. Any ideas what my problem might be?
Thank you,
Ray
