Function Documentation

void deInit (   )

Function to perform an controlled application "killing"

void display (   )

Method that is registered as rendering loop for GLUT and GLUI. Refer to LifeVariables.h for further description.

void enterArrowPlotMode (   )  throw (Error)

This function sets the program state to ARROW_PLOT_MODE if possible.

void enterLoadedMode (   )  throw (Error)

This set the program state to LOADED if possible.

void enterStreamlinePlotMode (   )  throw (Error)

This function sets the program state to STREAMLINE_PLOT_MODE if possible.

void enterUnloadedMode (   )  throw (Error)

This function sets the program state to UNLOADED if possible.

void eventListener (  int  control  )

This function is registered as callback for all events that happen on the Gui. Refer to LifeVariables.h for further description.

void idle (   )

Idle function just for the lazy computers. Here is no magic so there is no further description in LifeVariables.h

void keyEvent (  unsigned char  key, int  x, int  y )

Function to handle all keyboard events Parameters: key  the key pressed

void main (  int  argc, char *  argv[] )

Main method sets up the rendering context and creates the global objects. Currently the commandline parameters are not evaluated. Parameters: argc  not evaluated argv  not evaluated

void mouseEvent (  int  button, int  state, int  x, int  y )

This functions handles input events from the mouse. The only input from the mouse that should be handled is the seedpoint setting. Parameters: button  the GLUT constant of the button number wich had been pressed state  the state of the button (GLUT_UP, GLUT_DOWN) x  coordinate of the mouse cursor in pixel coordinates resp. to the whole window (regardless which subwindows of glui there are) y  coordinate of the mouse cursor in pixel coordinates resp. to the whole window (regardless which subwindows of glui there are)

void renderString (  int  x, int  y, void *  font, string  text )

Method to render a string as BitmapText on the screen. Refer to LifeVariables for further description.

void renderString (  int  x, int  y, void *  font, float  nr )

Method to render an integer as BitmapText on the screen. Refer to LifeVariables for further description.

void reshape (  int  x, int  y )

Function to handle reshape events. Refer to LifeVariables.h for further description.

void showGlDebugMessages (   )

Method to output debug messages from OpenGL. Refer to LifeVariables for further description.

Variable Documentation

CGrid colorGrid

The regulary resampled grid background texture

ProgramState currentProgramState = START

This variable holds the current ProgramState. All possible states and state-transitions are descibed in LifeVariables.h

bool debugMode = DEBUG_MODE

This boolean is a flag wich is set to 1 = true by default. Thus debug messages are passed to the console.

FileDialog* fileDialog = NULL

The dialog to open a path where raw files can be found

CGrid gGrid

The regulary resampled grid for arrow plots

CEuler gIntegration

The object which generates the streamline sample points

bool gNotSampled = false

Global Flag if the seedpoint should be resampled again or not

OrthographicCamera* mainCamera = NULL

The main rendering area which is left for the visualisation

int mainWindow = 0

windowname of the main rendering window assigned from glut

MenuBar* menuBar = NULL

The panel that emulates a menubar

float mouseX = 0

Mouse x coordinate in pixels responding to the mainCamera viewport

float mouseY = 0

Mouse y coordinate in pixels responding to the mainCamera viewport

OptionPanel* optionPanel = NULL

The panel that contains options for the visualisation

Background* pressureBackground = NULL

The background texture for the first dataset

RawReader* reader = NULL

The reader class which is used to load the datasets

sPoint2f seedPoint(0, 0)

The current interactive seedPoint

StateBar* stateBar = NULL

The panel that emulates a statebar

Background* vorticityBackground = NULL

The background texture for the 2nd dataset
