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¶

SoSFFloat heightAngle
Vertical angle of the viewing volume.

METHODS¶

SoPerspectiveCamera()
Creates a perspective camera node with default settings.

static SoType getClassTypeId()
Returns type identifier for this class.

ACTION BEHAVIOR¶

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