Constructor & Destructor Documentation

OpenGLCanvas::OpenGLCanvas	(	bool	defaultInteractionListeners,
		Gui *	gui = NULL,
		unsigned	width = (480),
		unsigned	height = (480)
	)

Parameters:

defaultInteractionListeners

if true will enable the basic, built-in, Maya-style user interactions via CTRL + mouse

Definition at line 17 of file OpenGLCanvas.cpp.

OpenGLCanvas::OpenGLCanvas	(	Gui *	gui = NULL,
		unsigned	width = (480),
		unsigned	height = (480)
	)

Constructs an OpenGLCanvas with default interaction listeners (Maya-style camera interactions).

Member Function Documentation

bool OpenGLCanvas::save

(

const char *

fileName

)

[virtual]

Attempts to saver this canvas' image to the specified file

Returns:

whether or not the save was successful

Implements Canvas.

Definition at line 44 of file OpenGLCanvas.cpp.

void OpenGLCanvas::lightOn

(

int

light

)

Turns the light on.

Definition at line 61 of file OpenGLCanvas.cpp.

void OpenGLCanvas::lightOff

(

int

light

)

Turns the light off.

Definition at line 66 of file OpenGLCanvas.cpp.

void OpenGLCanvas::lightPos	(	int	light,
		float	x,
		float	y,
		float	z
	)

Specifies the position of the light

Note:

Assumes current matrixMode is GL_MODELVIEW

Definition at line 71 of file OpenGLCanvas.cpp.
