Default Constructor eye (0,0,0) viewDir (0,1,0) Direction of viewing rays uDir (1,0,0) Vector from center to right edge. Image goes from -uDir to uDir vDir (0,0,1) Vector from center to top edge. Image goes from -vDir to vDir front (0)

    RiOrthoCamera();

RiOrthoCamera(const RiVector3 &eye, const RiVector3 &viewDir, const RiVector3 &uDir, const RiVector3 &vDir, RiReal front );

General Constructor

in eye: Center of the image plane
in viewDir: Direction of viewing rays
in uDir: Vector from center to right edge. Image goes from -uDir to uDir
in vDir: Vector from center to top edge. Image goes from -vDir to vDir
in front: front clipping plane in world units, not affected by the matrix.

    RiOrthoCamera(const RiVector3 &eye, const RiVector3 &viewDir,
		  const RiVector3 &uDir, const RiVector3 &vDir, RiReal front = 0);

void Transform(const RiAffineTMatrix3 &);

general manipulation of the camera. Some cameras may not allow a scale or perhaps even a rotation (Cylindrical panoramic), these need to catch or ignore this component of the matrix.

    virtual void Transform(const RiAffineTMatrix3 &);

RiRay3 GetRay( const RiVector2& screenCoord, const RiVector2& lensCoord ) const;

Screen coord is in the range[0,1]^2. (0,0) is lower-left corner. lensCoord is a seed in [0,1]^2 for lens sampling and is ignored for this RiRayCamera

    virtual RiRay3 GetRay( const RiVector2& screenCoord, const RiVector2& lensCoord ) const;
