List of all members.

Public Types

• typedef
  Eagle::PhysicalSpace::bivector bivector_t
• typedef Eagle::PhysicalSpace::point point_t

Public Member Functions

• bool operator!= (const VCamera &Other) const
• bool operator== (const VCamera &Other) const
• void reset ()
• VCamera ()

  Setup a default camera where the observer is located at (0,1,0), so at the y-axis, looking at the origin (0,0,0) with z-axis as up direction.
  

• VCamera (const point_t &Observer, const point_t &lookat=point_t(0, 0, 0), const bivector_t &UpVector=bivector_t(0, 0, 1))

  Setup a camera with view parameters.
  

• tvector3 viewdir () const

  The view direction.
  

• ~VCamera ()

  Destructor.
  

Public Attributes

• point_t LookAt

  The point that is watched.
  

• point_t Observer

  Location of the observer.
  

• bivector_t Up

  The horizontal plane, a bi-vector, whose dual is the up-direction.
  

• double ViewAngle

  Default view angle is 45 degrees.
