Enumeration Type Documentation

enum ProgramState

The program can reach these states of total destruction wich determine the content to be rendered in the main window. The states are evaluated in the display function of the main class and provide the following: START The State right after the start of the tool. In this state only the generic GUI is visible. The user can only click and select a file from the dropdown list or add/change the path to search for files. LOADING In this state, the program is loading some dataset from the disc. Thus the dataset is not rendered. If the loading succeeds, the program enters the LOADING_DONE state. LOADED In this state the volume data had been loaded from the disc. ARROW_PLOT_MODE In this state the program draws the arrow plot STREAMLINE_PLOT_MODE In this state the program draws the streamline plot. UNLOADING In this state the program cleans the memory allocated so far. Nothing is rendered to the screen. The state is left after the memory had been cleaned. The program enters then the state UNLOADED. UNLOADED In this state everything is cleaned - identical to START. Enumeration values: START  LOADING  LOADED  ARROW_PLOT_MODE  SWITCHING  STREAMLINE_PLOT_MODE  UNLOADING  UNLOADED

Function Documentation

void display (   )

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

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 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 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 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.
