void Avogadro::Navigate::rotate	(	GLWidget *	widget,
		const Eigen::Vector3d &	center,
		double	deltaX,
		double	deltaY
	)		[static]

Rotate about center by the amounts deltaX and deltaY in tha x and y axes.

Parameters:

widget	the GLWidget being operated on.
center	the point at the center of rotation.
deltaX	the amount to rotate about the x axis in degrees.
deltaY	the amount to rotate about the y axis in degrees.

void Avogadro::Navigate::rotate	(	GLWidget *	widget,
		const Eigen::Vector3d &	center,
		double	deltaX,
		double	deltaY,
		double	deltaZ
	)		[static]

Rotate about center by deltaX, deltaY, and deltaZ in the x, y and z axes A generalization of the rotate() and tilt() methods.

Parameters:

widget	the GLWidget being operated on.
center	the point at the center of rotation.
deltaX	the amount to rotate about the x axis in degrees.
deltaY	the amount to rotate about the y axis in degrees.
deltaZ	the amount to rotate about the z axis in degrees.

void Avogadro::Navigate::tilt	(	GLWidget *	widget,
		const Eigen::Vector3d &	center,
		double	delta
	)		[static]

Tilt about center by the amount delta z axis.

Parameters:

widget	the GLWidget being operated on.
center	the point at the center of rotation.
delta	the amount to rotate about the z axis in degrees.

void Avogadro::Navigate::translate	(	GLWidget *	widget,
		const Eigen::Vector3d &	what,
		const QPoint &	from,
		const QPoint &	to
	)		[static]

Translate between the from and to positions relative to what.

Parameters:

widget	the GLWidget being operated on.
what	the point that is being translated about.
from	the starting position.
to	the ending position.

void Avogadro::Navigate::translate	(	GLWidget *	widget,
		const Eigen::Vector3d &	what,
		double	deltaX,
		double	deltaY
	)		[static]

Translate between the from and to positions relative to what.

Parameters:

widget	the GLWidget being operated on.
what	the point that is being translated about.
deltaX	the amount to translate the x axis.
deltaY	the amount to translate the y axis.

void Avogadro::Navigate::zoom	(	GLWidget *	widget,
		const Eigen::Vector3d &	goal,
		double	delta
	)		[static]

Zooms toward a given point by the given amount.

Parameters:

widget	the GLWidget being operated on.
goal	the point that is being zoomed toward.
delta	the amount to zoom by.
