OpenGL Overlay Example

This is an example program i made for a friend of mine. The main goal was to show how to overlay a program that uses OpenGL with text and/or geometry. It is also good as external FPS counter (like Fraps) :) Comes with full source code (C++) and it is downloadable from my website: http://www.InsaneDevelopers.net/

The game i use to test it is called Urban Terror ( http://www.UrbanTerror.net/ )

can i use this aslo for directX programms? or does it only work on games that use opengl?

@MystBoy666 It only works for OpenGL applications.

do you know of any tools that are already available to overlay apps like pidgin/trillian into opengl/DX games?

[Togusa86]

@rokth There's a program named PLAYXPERT that is free and also looks good, though i haven't tried it. I'm sure it supports DirectX, but have no idea about OpenGL. It should come with an SDK, in case you want to write your own plugins!

[rokth]

is it possible to overlay anything into opengl?

[Togusa86]

@rokth You can overlay what you want :)
