i have 3 Activity . say a ,b, c . i have loaded obj model in "a" Activity then when i click on button it open "b" Activity and take image and open c Activity . In "c" Activity i want display same model which i loaded in "A" Activity. is any way so that i can save the time and use same loaded model instead of loading again
JPCT-AE doesn't bind itself to an Activity. You should be able to reuse the World instance in the third Activity. You might habe to create an additional instance of FrameBuffer though.
k will give a try and will let u knw ..
is it possible to apply pinch zoom to obj model
Yes, of course. But jPCT-AE doesn't provide any means for this. You have to use the default methods that the Android SDK offers for this and apply the results to your objects. jPCT-AE is not invasive. It doesn't force you into a specific way of structuring your app or making you use special input methods. It "just" does the rendering. Everything else is up to you.
