Does anyone know how to display bitmaps in 2d on the screen using scree coordinates like in DirectDraw. I realy need this to make a Menu.
I wanted to use DirectDraw but it doesnt work with Opengl.
-Thanks help very appreciated
I think you could try something like this:
Use a new projection matrix
now you can
to plot a vertex in the middle of the screen (the z value generaly dont care, cause i disable the depth buffer).
In addition you should notice that the coordonates (0,0) is the lower left conrner of the screen, but it is not really difficult to change this.
