I would appreciate any information on the module VectorGen.  This is how I
think it works.

I have 3d volumetric data of heart cusp.  The data looks like this.
Resolution 20 11 3
x coord   ycoord   z coord  function
3.0E+00   10.0E+00 4.0E+00   3.0E+00
.
.
.
When I use vectorgen in my map I get vectors at my coordinate points.  I
think that explorer takes the function value as the length of the vector
and uses an angle of 90 degrees as a default value.  This is how I think
it works.  

I am wondering how to get different angles for the vectors.  I would think
you would make your data look like this

Resolution 20 11 3
xcoord    ycoord   zcoord  function    vecx     vecy    vecz
3.0E+00   10.0E+00 4.0E+00 10.0E+00    3.0E+00  4.0E+00 10.0E+00 
.
.
.
The function value would correspond to the different colours you wanted. 
VECx, VEcy, Vecz would be used to calculate the angle and the length of
the vector.


If this is the way explorer does it, how does it differentiate between the
function value used for the colour map and the values used to calculate
the vector.

I am using DsCurvEX module to read in my data.  I modified this module for
the extra data and used vectorgen in my map.  It didn't quite work.  I don't
know if it is because of the dscribe module or the way I think explorer
works with vectorgen.
