Detailed Description

GL Studio standalone application class. Creates one window and draws all contents in it.

Constructor & Destructor Documentation

glsDisplayFrame	(	const char *	name,
		int	width,
		int	height
	)

Creates this glsDisplayFrame

Parameters

name	Window Title
width	Width of Dsplay Frame in pixels
height	Width of Dsplay Frame in pixels

Member Function Documentation

virtual void CenterOnLogical	(	float	lx,
		float	ly
	)

virtual

Causes the window to center the view on the specified logical coordinate. It takes into account the possible rotation of the top group.

Parameters

lx	Logical X Coordinate
ly	Logical Y Coordinate

virtual void Create ( void )

virtual

Creates this display frame. Called after the constructor so that things that need to access the OpenGL context can safely do so

virtual void CreateSplash ( )

virtual

Creates the spash screen

virtual void CurrentView ( const int view )

inlinevirtual

Sets the current view mode for the window

Parameters

view The new view mode for the window. Acceptable view types are: [VIEW_EYEPOINT - The application will be viewed through an eyepoint] [VIEW_XY - The application will be viewed through a 2D orthographic view of the XY plane] [VIEW_PERSPECTIVE - The application will be viewed through a perspective projection]

virtual int CurrentView ( void ) const

inlinevirtual

Gets the current view mode for the window.

Returns: The current viewmode for the window (VIEW_EYEPOINT, VIEW_XY, VIEW_PERSPECTIVE)

virtual void DepthFactor ( float factor )

virtual

Sets the Depth Factor for the window

Parameters

factor The depth factor. Used for autocalculating clipping planes

virtual float DepthFactor ( )

virtual

Gets the Depth Factor for the window

Returns: The current depth factor

virtual bool EscKeyExits ( )

virtual

Returns: Whether or not the ESC key exits application

virtual void EscKeyExits ( bool flag )

virtual

Enable/disable ESC key for exiting application

Parameters

flag	Whether or not ESC key exits application

virtual void FOV ( double fov )

virtual

Sets the FOV (Field of View) for the window. If fov is set to 0.0, a reasonable FOV will be calculated based on width and height.

Parameters

fov	New field of view in degrees

virtual double FOV ( )

virtual

Gets the FOV (Field of View) for the window.

Returns: The current field of view in degrees

virtual bool FrameAnimate ( void )

virtual

Redraw the window at the Hz rate set for the DisplayFrame, or at least try to. We might be slower if the hardware can't keep up.

virtual void GetWindowDimensions	(	int &	X,
		int &	Y,
		int &	W,
		int &	H
	)

virtual

Get the dimensions for the display frame window

Parameters

X	Gets X coordinate of window
Y	Gets Y coordinate of window
W	Gets width of window
H	Gets height of window

virtual void HeightOffset ( float offset )

virtual

Pans the display vertically

Parameters

offset The new Y position of the center of the window

virtual float HeightOffset ( void )

virtual

Gets the vertical position of the display at the center of the window

Returns: The Y position at the center of the window

virtual void PostDrawCallback ( GlsDrawCallback cb )

virtual

Sets the post draw callback to the function pointer passed in

virtual bool PostHandle	(	bool	handled,
		DisplayEvent *	ev
	)

virtual

Called after calling handle.

Parameters

handled	True when the event has already been handled
ev	the pointer to the the event

Returns: True If PostHandle has handled the event. Checks for statistics toggle [s] key, and [ESC] key press. The user can override this to turn off these behaviors.

virtual void PreDrawCallback ( GlsDrawCallback cb )

virtual

Sets the pre draw callback to the function pointer passed in

virtual void Redraw ( void )

virtual

Redraw the window now. This actually calls the OpenGL Drawing routines.

virtual void RemoveSplash ( )

virtual

Removes (hides) the spash screen

virtual void SetProjection ( void )

virtual

Sets up the default Orthographic projection (which supports things like pan and zoom)

virtual void SetRedraw ( void )

virtual

Set a flag that UpdateAnimate can test to see if the window needs redrawing.

Reimplemented from DisplayFrame.

virtual void SetWindowDimensions	(	int	X,
		int	Y,
		int	W,
		int	H
	)

virtual

Set the dimensions for the display frame window

Parameters

X	New X coordinate of window
Y	New Y coordinate of window
W	New width of window
H	New height of window

virtual bool SKeyTogglesStatistics ( )

virtual

Returns: Whether or not the 'S' key is enabled for controlling statistics

virtual void SKeyTogglesStatistics ( bool flag )

virtual

Enable/disable s key for toggling statistics

Parameters

flag	Whether or not S key will toggle statistics

virtual bool UpdateAnimate ( void )

virtual

Only draw on events or if SetRedraw has been called. If this is called in a main loop, updates can occur very frequently if SetRedraw is continuously being called.

virtual void WidthOffset ( float offset )

virtual

Pans the display horizontally

Parameters

offset The new X position at the center of the window

virtual float WidthOffset ( void )

virtual

Gets the horizontal position of the display at the center of the window

Returns: The X position at the center of the window

virtual void WindowFlags ( unsigned long flags )

virtual

Sets the mode flags for the window

Parameters

flags The mode flags

Member Data Documentation

bool _autoCalcFarZ

protected

When true a _farZ is automatically calculated.

bool _autoCalcNearZ

protected

When true a _nearZ is automatically calculated.

int _current_view

protected

Current view of the canvas (e.g., ortho, perspective, eyepoint)
