Shade_surf problem [message #41201]

Hi all,
I have a problem with shade_surf.
While trying to set the shading off, as suggested by the documentation *

IDL> device, decomposed=0

IDL> set_shading, gouraud=0, values=[1, 100]

IDL> shade_surf,indgen(10,10), ax=90, az=0

my surface is still shaded. What's wrong? Somebody, in a previous post, has
implicitly stated that set_shading works only with polishade.

Is he right?

Thank you very much in advantage.

Alex

*GOURAUD

This keyword controls the method of shading the surface polygons by the
POLYSHADE procedure. The SHADE_SURF procedure always uses the Gouraud
method. Set this keyword to a nonzero value (the default), to use Gouraud
shading. Set this keyword to zero to shade each polygon with a constant
intensity.
