Rahul,
I have CC'd the mailing list, just
so that if I give incorrect information, someone will correct it for you.
Anyway, I think you can still use GTK for the GUI, and still make use of X calls
directly. This may be your best bet. I know (as I stated in my
previous email) that GTK's graphics handling routines are SLOOOOW, so the answer
to rendering 3D images to the screen probably does not lie within this
library. Like I said, though, you can always use more than one
library. At least I would assume you could. Does anybody have a
solution?
Good
luck, and keep us posted

Hi
I am using OpenGL library
COSMO3D to display the graphics and the grphics is displayed on the
drawing area of the GTKWindow.....I am not using the GTK functions to render
the graphics.....
However I am amused by seeing
the poor speed of GTK drawing area which is unable to render the surface of
the graphics fastly..
Can you through some light on
it. I have already gone very far with the development and now I can
not cut GTK and choose another Front end developer.
Thanks a lot for your help.
Regards
Rahul Karurkar

Subject: RE: The speed of the
application is slow when we have little heavy graphics on the drawing area..
Please help
Hello,
Are you actually using GTK functions to display the graphics, or does
the OpenGL library actually display on the screen also? (versus just
copying to a memory structure, etc.) If you're using GTK
functions...they are sloooooow. To say the least. This is
actually a common complaint. It has to do with how GTK copies pixbufs,
etc. to X. Essentially, it does it pixel by pixel, which is REALLY
slow.
Anyway, good luck!

Hi all
I have been working on
this problem since long but could not get the result.
I am using GTK1.2 and
Cosmo3D(a opengl library). I have mapped Cosmo3D window onto Gtk drawing
area.
The speed I get with the
application seems slow. When I render the surfaces with graphics the
application goes slow and even menu click pops up menu after many
seconds......which is really inefficient.
Can anybody tell me how to maximise the speed
of the application with regard to the graphics rendering on gtk drawing
area rendering.
I feel I must have missed
something in mapping or There can be something which increases the speed
of graphics rendering.
The plateform I am working on is IRIX (SGI).
So I expected to have much more speedier but It becomes slow unexpectedly
when graphics come on the drawing area.
Thanks in advance.
Regards
Rahul
