void AppMain::ChangeBorder	(	const int	borderWidth,
		const int	depthAwareness
	)

Changes the width of the borders around the molecule atoms and depth awareness of the borders (both values between 0 and 255)

if the depth awareness is 0, the border width is equal for all atoms
if the depth awareness is increased, the width depends on the depth difference to next atom behind the current one.

Definition at line 393 of file AppMain.cpp.

void AppMain::ChangeColorMode ( int colorMode )

Updates the current color mode of the rendering.

colorMode: 0 = Color per atom, 1 = Color per chain, 2 = No color.

Definition at line 345 of file AppMain.cpp.

void AppMain::ChangeOcclusionQuality ( int occlusionQuality )

Updates the quality (=number of directions) used for ambient occlusion computation.

occlusionQuality: 0 = low, 1 = medium, 2 = high

Definition at line 349 of file AppMain.cpp.

void AppMain::MoveCamera	(	const double	x_translation,
		const double	y_translation
	)

Moves the camera in up/down and left/right (translation in x and y direction).

x_translation and y_translation determine the amount of the translation

Definition at line 255 of file AppMain.cpp.

void AppMain::MoveLight	(	const double	x_rotation,
		const double	y_rotation
	)

Rotates the the main light around the molecule (distance to molecule fixed).

x_rotation and y_rotation determine the strength of the rotation

Definition at line 250 of file AppMain.cpp.

void AppMain::RotateMolecule	(	const double	x_rotation,
		const double	y_rotation
	)

Rotates the molecule around the x and y axis.

x_rotation and y_rotation determine the strength of the rotation

Definition at line 244 of file AppMain.cpp.

void AppMain::ToggleAmbientOcclusion ( const bool ambientOcclusionActive )

Turns ambient occlusion on (ambientOcclusionActive = true) and off (ambientOcclusionActive = false)

If it is turned off, a constant value is used for the ambient lighting

Definition at line 399 of file AppMain.cpp.

void AppMain::UpdateWindowSize ( )

Updates the scene's camera projection matrix with the current window size.

Has to be called, when the window size changes!

Definition at line 291 of file AppMain.cpp.

void AppMain::ZoomInOut ( const double z_translation )

Moves the camera nearer to the molecule or farer away from the molecule.

Zoom in when z_translation is negative
Zoom out when z_translation is positive

x_translation also determines the amount of the translation
