2d graphics in OpenGL

Postby Vziuh » Sat Jul 30, 2011 2:29 pm

hi everyone !
i've started to work on user interface, i need to output some 2d graphics ( icons, different information windows ). but i didn't find ways i can do it in openGL, can you share the link where i can read something about it ?

the only way i find is to use as texture all my images on planes, but in this case i'll have to change these planes direction and position every time i change camera's direction and position, also lite source may have some effects on this planes.

The magic word you are looking for is orthographic projection. Just google for it.
