i think i have everything to work now except 1 thing ...
as i said earlier, i am adding a single point to a 3d surface plot. the
display that the 3d surface plot is on uses ScalarMaps to map
Display.RGB and Display.ZAxis to the same RealType for representing the
Z axis.
i cannot figure out how to set the color of this point that i added to
the plot. right now it always sets the color based on where it is on
the Z axis because of the Display.RGB that is mapped to the RealType for
Z.
I was curious if there is an easy way for me to leave the 3D surface
plot colored like it is now (based on where each point is on the Z
axis), but to have this single point always be a certain color (Green).
thanks a lot,
-Mike
