I am just curious how usually 2D-3D-2D transitions like what we can see on Apple OS such as “flipping” in iPhoto’09 are done. Basically we have a begin 2D QUAD and end 2D QUAD, we want a 3D plane transitions in between them.
I am just wondering if there is a general way to setup 3D camera’s properties so that the beging and ending 3D plane projections coincide with the specified 2D QUADs.
That is, knowing projections of a 3D size-known plane in screen space, how can we solve the 3D camera’s transition setting-ups ?
Any suggestions are welcome
