Hi Clement, I can't really make much sense from your post so can't make any specific suggestions. General comments I would add are that different graphics hardware supports different Texture3D resolution, you have to keep within this to be able doing volume rendering. Also if you don't set up th

No, as it is pretty heavily tied into other source that can not be made available. I can probably post the code for how the HUD and the object to be placed in the upper right hand corner are being created if that would help though. IE the posted code would not run on its own. --

Yes it works you just need to change it in ALL the Android.mk because it's defined in each script file. That's why I said that I need to make another sumission adding optional optimization WHICH will overwrite every .mk.inwhen it's added to the main library. 2011/9/13 Marc Sticksen > Hi, > > onl
