View Full Version : frame updating

09-21-2004, 06:30 AM
hey im totally new to openglES i've worked with opengl a lot. I think my code is correct, it basically comes from the redbook but it doesnt seem to update the frames. So i increased a counter with every frame and printed a message box to see if it's updated. Weird thing is when i print the box it actually updates...

that's my code:

the util functions are not necessary, oh and im using the emulator 2003 only atm.

Is there anything i should know?

thanks :D

You need to hook up a timer event to trigger repeated updates. I think the message box essentially invalidates your windows rect, that's why you get a redraw.

The alpha3d.c demo from the redbook examples should demonstrate how to set up an animation loop.

Hope that helps,

The best way to refresh the screen is to call ugPostRedisplay(uwin) after swapping buffer isn't it ?

That will trigger an immediate redraw. If you need a steady framerate, you'd be probably better off with the timer approach.
