2d :)


i’m new to ogl sdk and used to using dx. I’m looking at an easy way to display an image that fills the screen (320,240). I’m looking at glOrtho but past that i’m stuck. can n e 1 point me to simple code to show me how to do this? the device i’m programming for (gizmondo) supports ddraw but because i need fading etc. i’d rather stick to ogl es :slight_smile:


You can do that without changing any matrices at all, you can leave them on the Identity matrix. Check out, for example, the render of the background quad in this demo:


Try looking at the function RenderBackground().


Can you tell us how long does it takes to bitblit a fullscreen image the opengl way on the gizmoodo ?
