Constructor & Destructor Documentation

GlutWindow2d::GlutWindow2d	(	const char *	title,
		int	width = `800`,
		int	height = `800`
	)

Basic constructor

GlutWindow2d::~GlutWindow2d ( )

virtual

Basic destructor

Member Function Documentation

void GlutWindow2d::display ( )

virtual

This will setup the camera and then call draw().

Implements GlutWindow.

virtual void GlutWindow2d::draw ( )

pure virtual

Override this function to draw the scene. This function is called from the display function automatically.

Implemented in ParticlePlot.

void GlutWindow2d::drawText2d	(	const char *	txt,
		float	x,
		float	y,
		float	r,
		float	g,
		float	b,
		void *	font
	)

protected

This will draw the given string to the screen at the location given by x,y- (relative to the current window properties). the color defaults to a gray

void GlutWindow2d::drawZoomCircle ( )

protected

Draws the zoom circle when changing the zoom factor

void GlutWindow2d::init ( )

protectedvirtual

Setups and Initializes the window

Implements GlutWindow.

void GlutWindow2d::mouse	(	int	button,
		int	state,
		int	x,
		int	y
	)

virtual

This is used in conjunction with mouseMotion to provide the camera movement.

Parameters

button	The button that was pressed
x	The x location of the cursor when the button was pressed
y	The y location of the cursor when the button was pressed

This is used in conjunction with mouseMotion to provide the camera movement. Moving the mouse with the left button down rotates the camera around a fixed point (specified by viewX, viewY, viewZ). Moving the mouse with the right button down zooms the camera in and out

If you would like to perform other operations with the mouse, override this function, you may want to consider calling Glut_Window::mouse() in that routine to maintain the mouse interface.

Parameters

button	The button that was pressed
x	The x location of the cursor when the button was pressed
y	The y location of the cursor when the button was pressed

Reimplemented from GlutWindow.

void GlutWindow2d::mouseMotion	(	int	x,
		int	y
	)

virtual

This routine is called whenever a mouse movement event has occured.

Parameters

x	The x location of the mouse
y	The y location of the mouse

This routine is called whenever a mouse movement event has occured. If you are overriding it, consider calling Glut_Window::mouse_motion() in your descendant classes, to maintain the mouse interface

Parameters

x	The x location of the mouse
y	The y location of the mouse

Reimplemented from GlutWindow.

void GlutWindow2d::positionCamera ( )

virtual

Overide this function to change the location from which the scene is rendered. It currently uses information from the mouse and the special keyboard keys to set its direction

Reimplemented from GlutWindow.

void GlutWindow2d::processNormalKeys	(	unsigned char	key,
		int	x,
		int	y
	)

virtual

This function is called when an ascii key is pressed.

Parameters

key	The key that was pressed
x	The x location of the cursor when the key was pressed
y	The y location of the cursor when the key was pressed

Reimplemented from GlutWindow.

Reimplemented in ParticlePlot.

void GlutWindow2d::processSpecialKeys	(	int	key,
		int	x,
		int	y
	)

virtual

This function is used to perform actions when one of the non-ascii keys are presed.

Parameters

key	The key that was pressed
x	The x location of the cursor when the key was pressed
y	The y location of the cursor when the key was pressed

This function is used to perform actions when one of the non-ascii keys are presed. In the base class, the arrow keys are used to move the center of the field of view around in the plane, while PAGE_UP & PAGE_DOWN are used to change the Z value of the center of view.

If you would like to perform other options with the special keys, then when overriding this function, you may want to consider calling GlutWindow2d::processSpecialKeys(key, x, y) in the overridden function to maintain the same base functionality.

Parameters

key	The key that was pressed
x	The x location of the cursor when the key was pressed
y	The y location of the cursor when the key was pressed

Reimplemented from GlutWindow.

void GlutWindow2d::reshape	(	int	w,
		int	h
	)

virtual

This performs generic graphics matrix setup operations, and will be called if the user resizes the window

Parameters

w	Width of the window
h	Height of the window

Implements GlutWindow.

void GlutWindow2d::setProjectiveSettings ( )

protected

Set the projection parameters

Member Data Documentation

bool GlutWindow2d::drawZoomCircleFlag

protected

double GlutWindow2d::mousePanXOffset

protected

Remember where the pan x offset started from when the mouse is clicked

double GlutWindow2d::mousePanYOffset

protected

Remember where the pan y offset started from when the mouse is clicked

double GlutWindow2d::mouseStartZoom

protected

Remember where the zoom started from

double GlutWindow2d::panXOffset

protected

The value for the panning in the x direction

double GlutWindow2d::panYOffset

protected

The value for the panning in the y direction

double GlutWindow2d::zoomDrawRadius

protected

The zoom radius for drawing purposes

double GlutWindow2d::zoomFactor

protected

Factor to adjust the zoom
