I think (I haven't tried it really either) that ONGLASS is similar
to using hardware fonts in direct graphics. Yes, it makes the text
visible, but you lose the rotational capability. I think you can
probably have one or the other, but not both together.
If I'm wrong, I trust someone will correct me. ;-)
Cheers,
David

It looks like the IDLgrTEXT may have an answer with the ONGLASS property.
Have not tried that one (or any of the oog stuff) yet.

Holger Schaal wrote a question I can't answer, but I would like to
show you something completely different -
Here are nine lines of his code which can completely substituted
by one line
> E_y0_thick = fltarr(74, 9)
> i = 0
> j = 0
> For i = 0,73,1 do begin
> For j = 0,8,1 do begin
> y = 2. * cos(x[i]) / sqrt(1. - n_21[j]^2)
> E_y0_thick[i,j]=y

> endfor
This is the one line that does the same thing ;-)
E_y0_thick = 2. * cos(x) # (1. / sqrt(1. - n_21^2))
Best regards
Kevin

I can't think of any way to solve this text rotation
problem without adding the textual annotation yourself,
(e.g., with XYOutS) which almost certainly will be a
frustrating and difficult exercise.
Let me recommend an alternative. If you make it
easy for the user to rotate the surface interactively,
then the annotations will not be as much of a problem
as they are in a fixed view. A program like XSURFACE,
which you can download from my web page, would make this
possible.
This does not, of course, solve the problem of *printing*
the results, but it is difficult for me to see how
the antagonistic goals of rotatable 3D text and always-readable
text can both be obtained.
Cheers,
David
