Detailed Description

Lets you get raw and calculated camera data from an STV file.

An STV file gives information on intrinsic and extrinsic camera parameters.

• intrinsic parameters: field of view, aspect ratio
• extrinsic parameters: where the camera is, and what direction it's looking in

Member Function Documentation

Vertex StvFile::calculateLookatPoint (    )  const

Get a lookat point. Invariant: This method assumes that we are looking roughly towards the origin. We could really set the lookat point to be an arbitrary distance away -- it's just specifying direction. So we pick a point along the eye ray that is closest to the origin.
