Detailed Description

Encapsulates camera pose in a 3D scene.

The pose is defined with the following parameters:

• center point - towards which point the camera is looking
• distance from the center point - how far is the camera from the point towards which it is looking
• pitch angle - vertical rotation of the camera (0 degrees = camera looking down, 90 degrees = camera looking from the side)
• yaw angle - horizontal rotation of the camera
