void Hud::printGLHelp

(

bool

print

)

Prints the help-box in the lower left corner of the window.

Parameters:

print

True: Label is printed. False: Label is not printed.

void Hud::printGLLabel

(

)

Prints the labels 'Depth Map' and 'Video Output' using printGLTextPos(int x, int y, std::string text, bool printLarge).

void Hud::printGLScanning

(

bool

print

)

Prints a 'Scanning'-label in the middle of the depth-map-frame while scanning.

Parameters:

print

True: Label is printed. False: Label is not printed.

void Hud::printGLState	(	bool	print,
		int	angle,
		std::string	format,
		bool	states[5]
	)

Prints the state-box in the lower right corner of the window.

Parameters:

print	True: Label is printed. False: Label is not printed.
angle	The current Kinect's angle.
format	String with the current format of the video stream. Should be 'RGB', 'YUV-RGB' or 'IR'.
states	Array with 5 element indicating the steps of the pointcloud reconstruction. The meaning of the steps are explained at KinectCloud::getReconstructionSteps().

void Hud::printGLText	(	std::string	text,
		bool	printLarge
	)

Prints text using OpenGL's glutBitmapCharacter(void *font, int character) without specifying a certain position.

Parameters:

text	The text which should be printed.
printLarge	False: Text is printed with OpenGL's GLUT_BITMAP_HELVETICA_12. True: Text is printed with GLUT_BITMAP_HELVETICA_18.

void Hud::printGLTextPos	(	int	x,
		int	y,
		std::string	text,
		bool	printLarge
	)

Calls printGLText(std::string text, bool printLarge) after setting a specified position using OpenGL's glRasterPos2i(GLint x, GLint y).

Parameters:

x	X-coordinate of the wanted text-position.
y	Y-coordinate of the wanted text-position.
text	The text which should be printed.
printLarge	False: Text is printed with OpenGL's GLUT_BITMAP_HELVETICA_12. True: Text is printed with GLUT_BITMAP_HELVETICA_18.
