#define ClassDef(name, id)
Concrete class describing an orientated (free) or axis aligned box of 8 vertices.
Abstract base camera class - concrete classes for orthographic and perspective cameras derive from it...
virtual Bool_t Truck(Double_t xDelta, Double_t yDelta)
Truck the camera - 'move camera parallel to film plane'.
Orthographic projection camera.
virtual void Reset()
Reset the camera to defaults - trucking, zooming to reframe the world volume established in Setup().
void SetZoomMax(Double_t z)
Set maximum zoom factor.
Bool_t GetDollyToZoom() const
virtual Bool_t Truck(Int_t xDelta, Int_t yDelta, Bool_t mod1, Bool_t mod2)
Truck the camera - 'move camera parallel to film plane'.
void SetDollyToZoom(Bool_t x)
Double_t fZoom
x, y size of scene from camera view
virtual Bool_t IsOrthographic() const
virtual Bool_t Dolly(Int_t delta, Bool_t mod1, Bool_t mod2)
Dolly the camera.
Bool_t GetEnableRotate() const
void SetEnableRotate(Bool_t x)
Double_t GetZoomMax() const
virtual ~TGLOrthoCamera()
Destroy orthographic camera.
virtual void Setup(const TGLBoundingBox &box, Bool_t reset=kTRUE)
Setup camera limits suitable to view the world volume defined by 'box' and call Reset() to initialise...
static UInt_t fgZoomDeltaSens
virtual Bool_t Zoom(Int_t delta, Bool_t mod1, Bool_t mod2)
Zoom the camera - 'adjust lens focal length, retaining camera position'.
Double_t GetZoomMin() const
virtual void Configure(Double_t zoom, Double_t dolly, Double_t center[3], Double_t hRotate, Double_t vRotate)
Configure the camera state.
void SetZoomMinMax(Double_t min, Double_t max)
TGLOrthoCamera()
Construct kXOY orthographic camera.
Double_t fDefXSize
scene volume
void SetZoomMin(Double_t z)
Set minimum zoom factor.
virtual void Apply(const TGLBoundingBox &sceneBox, const TGLRect *pickRect=0) const
Apply the camera to the current GL context, setting the viewport, projection and modelview matrices.
virtual Bool_t Rotate(Int_t xDelta, Int_t yDelta, Bool_t mod1, Bool_t mod2)
Rotate the camera - 'swivel round the view volume center'.
Viewport (pixel base) 2D rectangle class.
3 component (x/y/z) vector class.
void box(Int_t pat, Double_t x1, Double_t y1, Double_t x2, Double_t y2)
