android - how to find range of Normalized Device Co-ordinates? -



i new opengl programming.
know ndc ranges [-1, 1] on both axis 0,0 in center. trying increase range , doing via gltranslatef(0,0,-11.0f) gives me more room.

but dont know new ndc range after gl call. can body please explain ?

you need first try understand life of vertex in opengl pipeline (an example here). otherwise find hard understand doing. can frustrating @ begining.

the simple answer question ndc coordinates always in range of [-1, 1]. cannot change , shouldn't need change that.

what do want change though, modelview , perspective matrices objects have more space in screen. example gltranslatef(0,0,-11.0f) command, moves object down on negative z axis (where "camera" looks @ default i.e. away eye). since object farther away seems smaller, have more screen space.

another set of tutorials have personaly found helpful opengl es ground up (they iphone principles same)
