Detailed Description

Fly view handler

This handler implements a fly navigation mode that can be used together with CIvfWidgetBase derived classes, such as CIvfFltkBase, CIvfWin32Window, CIvfMfcBase etc. The class take a reference to the active widget and a CIvfCamera derived class.

Controls:

w - Increase velocity
s - Decrease velocity
x - Sets velocity to zero.
q - Increase vertical velocity
a - Decrease vertical velocity

Examples:

handlers.cpp.

Member Function Documentation

double CIvfFlyHandler::getMaxSpeed (   )

Return max speed

double CIvfFlyHandler::getMouseSensitivity (   )

Return mouse sensitivity

double CIvfFlyHandler::getSpeedStep (   )

Return current speed step value

virtual void CIvfFlyHandler::onKeyboard (  int  key, int  x, int  y )  [virtual]

onKeyboard method The onKeyboard method is called when a key on the keyboard is pressed Reimplemented from CIvfKeyboardEvent.

virtual void CIvfFlyHandler::onMouseDown (  int  x, int  y )  [virtual]

onMouseUp method The onMouse method is called when the mouse button is released. Reimplemented from CIvfMouseDownEvent.

virtual void CIvfFlyHandler::onMouseMove (  int  x, int  y )  [virtual]

onMouseMove method The onMouseMove method is called whenever the mouse is moved in the window. Reimplemented from CIvfMouseMoveEvent.

virtual void CIvfFlyHandler::onMouseUp (  int  x, int  y )  [virtual]

onMouseMove method The onMouseMove method is called whenever the mouse is moved in the window. Reimplemented from CIvfMouseUpEvent.

void CIvfFlyHandler::setMaxSpeed (  double  speed  )

Set maximum speed

void CIvfFlyHandler::setMouseSensitivity (  double  value  )

Set mouse sensistivity The mouse sensitivity is used determine the turning/rotate speed when the mouse is moved: mouse_delta_x * sensitivity * dt mouse_delta_y * sensitivity * dt

void CIvfFlyHandler::setRedraw (  bool  flag  )

Set redraw handling The fly handler can handle screen redrawing automatically (flag=true) Sometimes it can be effective to control redrawing manually (flag=false)

void CIvfFlyHandler::setSpeedStep (  double  step  )

Set speed step The speed step value determines how much the speed increases or decreases when the user presses the forward/back button (W/S) to increase/decrease the forward velocity.

void CIvfFlyHandler::update (   )

View update routine The fly handler needs to be updated regularly. This routine updates the state variables and the camera depending on the elapsed time. Typically this routine should be called from a timer or an application loop.
