The Position property on the KFbxCamera is deprecated. It was used back in the days when “Producer Cameras” were always contained in FBX files.

As of now, the official way to retrieve the camera position is to find the node attached to it (there might be more than one) and get the property LclTranslation.

So,if i want to get something like view matrix in openGL,then that it is as well???

Related to this topic, I recently added three new functions to the FbxCamera class in FBX 2013.0 Beta3 (If you have access to Beta boards, you can test this out).

They will be the following:

These new functions will make it much easier to build the view matrix once the three vectors are fetched. These functions will not only take care of the subtle things mentionned in this thread, but also taking care of animation, if any. Until FBX 2013 is out, it is extremely difficult to get these values since there is a lot of quirks and traps.
