ArcGIS.Desktop.Mapping Namespace / Camera Class / Pitch Property
Version

Pitch Property (Camera)
Gets or sets the Pitch of the Camera, in degrees from horizontal. 0 is horizontal, 90 is looking directly up and -90 is looking directly down. This property applies to 3D views only.
Syntax
public double Pitch {get; set;}
Remarks
Heading, Pitch and Roll are used to describe the viewing direction in a 3D view. Pitch defines the angle of the camera rotating around the X-axis. Imagine yourself as the camera. In this case adjusting the pitch would be equivalent to looking up or down. The valid range for pitch is -90 (looking directly down) to 90 (looking directly up). Pitch has no effect in 2D it will always be -90.
