Member Function Documentation

CullModeMenu()

void Window::CullModeMenu ( int  entry )

static

This function is called when the user updates the cull mode in the drop-down menu.

DisplayFunction()

void Window::DisplayFunction ( void  )

static

This function draws the OpenGL window.

DrawModeMenu()

void Window::DrawModeMenu ( int  entry )

static

This function is called when the user updates the draw mode in the drop-down menu.

IdleFunction()

void Window::IdleFunction ( void  )

static

This function is called when no events need to be processed.

InterpolationTypeMenu()

void Window::InterpolationTypeMenu ( int  entry )

static

This function is called when the user updates the curve fitting method in the drop-down menu.

KeyboardFunction()

void Window::KeyboardFunction ( unsigned char  c, int  x, int  y  )

static

This function is called when the user presses a key.

MainMenu()

void Window::MainMenu ( int  entry )

static

This function is called when the user selects one of the main menu options in the drop-down menu.

MotionFunction()

void Window::MotionFunction ( int  x, int  y  )

static

This function is called when one of the mouse buttons is depressed and the mouse is moved.

MouseFunction()

void Window::MouseFunction ( int  button, int  state, int  x, int  y  )

static

This function is called when the state of a mouse button is changed

ParametrizationTypeMenu()

void Window::ParametrizationTypeMenu ( int  entry )

static

This function is called when the user updates the rotation parametrization method in the drop-down menu.

PassiveMotionFunction()

void Window::PassiveMotionFunction ( int  x, int  y  )

static

This function is called when the mouse is moved moved but no buttons are depressed.

PrintError()

int Window::PrintError ( int  showNoError = 0 )

static

This function prints out the state of the OpenGL error.

ReshapeFunction()

void Window::ReshapeFunction ( int  width, int  height  )

static

This function is called when the window is resized.

SetEvaluators()

void Window::SetEvaluators ( void  )

static

This function (re)sets the evaluators

SpecialFunction()

void Window::SpecialFunction ( int  key, int  x, int  y  )

static

This function is called when the user presses one of the special keys.

TakeSnapshot()

Image32 Window::TakeSnapshot ( void  )

static

This function reads the current frame buffer and sets the pixels of the image accordingly.

View()

void Window::View ( Scene &  scene, int  width, int  height  )

static

This function instantiates the OpenGL window, reading in the Scene from the specified file and setting the initial OpenGL window size. The function never returns.

VisibilityFunction()

void Window::VisibilityFunction ( int  state )

static

This function is called when the visibility state of the window changes.

WriteLeftString()

void Window::WriteLeftString ( int  x, int  y, const std::string &  str  )

static

This function writes out the specified string, left-aligned, at the specified location, onto the OpenGL window.

WriteRightString()

void Window::WriteRightString ( int  x, int  y, const std::string &  str  )

static

This function writes out the specified string, right-aligned, at the specified location, onto the OpenGL window.
