i wanted to know how to implement something like a explorer where i can view different object by rotating my camera view to see other objects or have a different view of the same object…
That sounds quite vague, an example or better description?
(Do you mean like those 3D demos of mobiles that you can get?)
look for a first person mouselook script in tutorialsforblender3d.com
maybe that would help.
