Hello everybody,
I recently upgraded to V0.88 which reminds me to an old problem
concerning colortables for glcanvases on linux systems. I am
not sure whether this is a bug or I make something wrong during
the initialization of Forms and Mesa/OpenGL.
The glcanvas seems to have the wrong colortable on linux systems.
While simple graphics using only red/green/blue like the gl demos
in the forms distribution work, scenes with more colors (especially
when lighting is used) look like they are based on a wrong colortable.
I looked around in the gl.c file coming with the library and found
out that removing the fl_set_canvas_colormap statement (l.182 in
V0.88) solves the problem (whatever this means?).
On SGI computer with OpenGL the application works fine as well
as on SUN computers running Solaris (without a change in gl.c).
Has anybody seen something similar or has an idea what may cause
this behaviour? I can send a more detailed description if this
is of further interest.
