can anyone point me towards a good guide of how to go about 2D maniuplation in a general app, but in opengl? all i need to make is like a 2d version of a modelling tool (from one perspective) as its just for easily making and manipulating a network of nodes i just cant seem to get a right combination of mixing 3d and 2d to make a useable interface all i need is a good 2d guide, or the bones of an editor (map/moddelling both can easily be applied) then i can add format loading and things. all i need to do is plop down nodes, edit a value or 2 and then select it to add more linked to it. __________________ graham "red" reeves. red@deadpenguin.org www.deadpenguin.org
