It is not the problem of opengl or windows XP. But the compatibility of opengl and video drivers. I don't know how to solve.

Hi Rathi
No problem.
It's time for upgrading hardware
Please continue your software development for OpengL support in HMG.

Hello Rathi,
Thanks a lot
I tested it.
After building it showed distorted graphics. I closed it. Then I ran again. I showed following picture.

Yes Sudip, it is the incompatibility of Windows XP graphics drivers and openGL.
In Vista, it works fine.

No problem, friend Rathi. Please continue the project
For some reasons, I am not able to test it on Vista right now. Can you please show some image output in Vista? So that, I can understand what it should be.
With best regards.

Is the OpenGL library still being developed?
I just ran the example on my XP netbook but suffered the same problem other users were having with distorted background imagery. I've done some OpenGL programming in the past & was able to solve the problem by adding the following lines in the c_graphics.c file.
Code: Select all
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glLoadIdentity();
The problem was that the screen wasn't being cleared before drawing, the lines above fix that.
