SoPerspectiveCamera — perspective camera node

Action Behavior

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

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

SoSFFloatheightAngle
          Vertical angle of the viewing volume.
