Detailed Description
a virtual camera for 3D rendering
vtkCamera is a virtual camera for 3D rendering. It provides methods to position and orient the view point and focal point. Convenience methods for moving about the focal point also are provided. More complex methods allow the manipulation of the computer graphics model including view up vector, clipping planes, and camera perspective.

Set/Get the camera view angle, which is the angular height of the camera view measured in degrees. The default angle is 30 degrees. This method has no effect in parallel projection mode. The formula for setting the angle up for perfect perspective viewing is: angle = 2*atan((h/2)/d) where h is the height of the RenderWindow (measured by holding a ruler up to your screen) and d is the distance from your eyes to the screen.

Set/Get the scaling used for a parallel projection, i.e. the height of the viewport in world-coordinate distances. The default is 1. Note that the "scale" parameter works as an "inverse scale" — larger numbers produce smaller images. This method has no effect in perspective projection mode.

| void vtkCamera::Zoom | ( | double | factor | ) |
In perspective mode, decrease the view angle by the specified factor. In parallel mode, decrease the parallel scale by the specified factor. A value greater than 1 is a zoom-in, a value less than 1 is a zoom-out.
Set/Get the location of the near and far clipping planes along the direction of projection. Both of these values must be positive. How the clipping planes are set can have a large impact on how well z-buffering works. In particular the front clipping plane can make a very big difference. Setting it to 0.01 when it really could be 1.0 can have a big impact on your z-buffer resolution farther away. The default clipping range is (0.1,1000). Clipping distance is measured in world coordinate unless a scale factor exists in camera's ModelTransformMatrix.

Get/Set the oblique viewing angles. The first angle, alpha, is the angle (measured from the horizontal) that rays along the direction of projection will follow once projected onto the 2D screen. The second angle, beta, is the angle between the view plane and the direction of projection. This creates a shear transform x' = x + dz*cos(alpha)/tan(beta), y' = dz*sin(alpha)/tan(beta) where dz is the distance of the point from the focal plane. The angles are (45,90) by default. Oblique projections commonly use (30,63.435).
