DESCRIPTION
A perspective camera defines a perspective projection from a viewpoint. The viewing volume for a perspective camera is a truncated right pyramid. By default, the camera is located at (0,0,1) and looks along the negative z-axis; the position and orientation fields can be used to change these values. The heightAngle field defines the total vertical angle of the viewing volume; this and the aspectRatio field determine the horizontal angle.
FIELDS
c
}
c
}
heightAngle
Vertical angle of the viewing volume.
METHODS

ACTION BEHAVIOR
SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoHandleEventAction, SoRayPickAction
Sets the viewport and camera information in the state.
