We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Camera API documentation missing
I could not find a list of available cameras in the docs:

http://vispy.org/scene.html?highlight=cameras#module-vispy.scene.cameras


--- END ISSUE ---

Below are some code segments, each from a relevant file. One or more of these files may contain bugs.

5 Cameras are responsible for determining which part of a scene is displayed
6 in a viewbox and for handling user input to change the view.
7 
8 Several Camera subclasses are available to customize the projection of the 
9 scene such as 3D perspective and orthographic projections, 2D 
10 scale/translation, and other specialty cameras. A variety of user interaction
11 styles are available for each camera including arcball, turntable, 
12 first-person, and pan/zoom interactions.

14 Internally, Cameras work by setting the transform of a SubScene object such 
15 that a certain part of the scene is mapped to the bounding rectangle of the 
16 ViewBox.
