I am a fourth year engineering student.  Eventually I will be
mapping collagen fibre orientation ont a 3d model of a heartvalve.
The orientation data is in the form of a histogram.  The horizontal
axis is from 0 to 180 degrees.  The veritcal axis is the number of
collegen fibres. I have histograms for various points on the
heartvalve.

I have read the users manual and the man descriptions of the
modules.  I also have the module writers guide.  I also have read
some of the info at ftp sites (139.88.54.33)

I have tried using explorer but without sucess.  I have tried doing
doing simple examples such as creating a 3d data file and trying
to get an image using explorer. I have created a data file
(xcord,ycordin,zcord,value) that looks like this.
10
10 11 12 1000
20 21 22 2000
30 31 32 3000
.  .  .  .
.  .  .  .
.  .  .  .
100 101 102 10000

I then went to dscribe and created an input template with a vector
glyph with n=10 and an 3d array glyph with n1=10,n2=10,n3=10. I
then created and ouput template. I tried all the differet types of
3d lattices and I let nDataVar=1.  I used this module in the map
editor and I connected it to VolumetoGeom and then to render.  I
did not get an output.

I would appreciate simple examples of how to input images
such as the coordinates of a cube and then how to map 2d arrays
onto specific points on a cube.


Also, how do you pick which modules to use.  I have read the man
pages on them but it does not seem much help
