Hello All,

I am currently in the initial stages of a surface
water flow visual application.

I am reading and displaying an ASCII DEM and I am
displaying the amount of water in each grid cell after
a precipitation event.

You can see a couple of screen shots here:

I want to add flow directional arrows.  I store the
flow direction for each cell as a directional degree.
(45,90,135....360)

I took a look at Test28, but I do not see how to build
the arrows with my data.

any advice is appreciated,
-Jay
