Today I made the starmap 3d! (like in Elite 2). There are 2 problems however, the camera control is hideous and I havnt figured out how to detect mouse clicks on 3d objects are there any resources about cameras/rotaton and mouse input?

Have a look on these functions in the sdk documentation:

D3DXVec3Unproject(...)
D3DXVec3project(...)

D3DXPlaneIntersectLine(...)
D3DXSphereBoundProbe(...)
D3DXIntersectTri(...)
D3DXIntersectSubset(...)
D3DXBoxBoundProbe(...)

and have a look on the the SDK Sample "pick".
Hope this helps
