Constructor & Destructor Documentation

VisualCamera::VisualCamera ( )

Constructor of VisualCamera.

VisualCamera::~VisualCamera ( )

The destructor.

VisualCamera::VisualCamera ( const VisualCamera & other )

Copy constructor.

Parameters:

other Reference to another VisualCamera.

Member Function Documentation

void VisualCamera::activate ( void )

Activates the camera with its current settings.

Remarks:: The camera sets up the remembered projection mode.

void VisualCamera::copy ( const VisualCamera & other ) [private]

Copy method for assignment operator and copy constructor.

Parameters:

other Another VisualCamera.

VisualCamera * VisualCamera::createDefaultCamera ( void ) [static]

Static function which creates a camera with default orientation (orthographic projection).

Returns:: A camera with default orientation (orthographic projection).

Remarks:: Caller has to delete the camera instance by calling delete.

double VisualCamera::getCoordHeight ( void ) const

Returns the height of the camera view.

Returns:: The height of the camera view.

double VisualCamera::getCoordWidth ( void ) const

Returns the width of the camera view.

Returns:: The width of the camera view.

double VisualCamera::getDepth ( void ) const

Returns the depth of the camera view.

Returns:: The depth of the camera view.

double VisualCamera::getMaxBottomCoord ( void ) const

Returns the maximum bottom position.

Returns:: The maximum bottom position.

double VisualCamera::getMaxFarPos ( void ) const

Returns the maximum far position.

Returns:: The maximum far position.

double VisualCamera::getMaxLeftCoord ( void ) const

Returns the maximum left position.

Returns:: The maximum left position.

double VisualCamera::getMaxNearPos ( void ) const

Returns the maximum near position.

Returns:: The maximum near position.

double VisualCamera::getMaxRightCoord ( void ) const

Returns the maximum right position.

Returns:: The maximum right position.

double VisualCamera::getMaxTopCoord ( void ) const

Returns the maximum top position.

Returns:: The maximum top position.

CoordSize3D VisualCamera::getSize ( void ) const

Returns the 3D dimensions of the camera view.

Returns:: The 3D dimensions of the camera view.

void VisualCamera::lookAt	(	Point3D	eye,
		Point3D	center,
		Vector	up
	)

Performs a viewing transformation.

Parameters:

eye	The position of the eye point.
center	The position of the reference point.
up	the direction of the up vector.

VisualCamera & VisualCamera::operator= ( const VisualCamera & other )

Assignment operator.

Parameters:

other Reference to another VisualCamera.

void VisualCamera::setOrthographicProjection ( )

Sets up an orthographic projection matrix of GL.

void VisualCamera::setPerspectiveProjection ( double nearClippingPlanePos = 1.0 )

Sets up the perspective projection matrix of GL.

Parameters:

nearClippingPlanePos The maximum near position. With the maxNearCoord the position of the near clipping plane of the viewing volume is set. By setting maxNearCoord the perspective projection (the shape of the viewing volume) can be adjusted. The value of maxNearCoord must be positive.
