Constructor & Destructor Documentation

CCameraControl()

DirectGraphicalModels::vis::CCameraControl::CCameraControl	(	GLFWwindow *	window,
		float	theta = 0.0f,
		float	phi = -glm::pi<float>() / 2,
		float	radius = 2.4f,
		float	turnSpeed = 0.004f,
		float	scrollSpeed = 0.33f,
		float	panSpeed = 0.01f
	)

Constructor.

The camera is defined in polar coordinate system with the parameters theta, phi and radius in point \(P\) and looks at the origin \(O\), which is initially situated at the zero point.

Parameters

window	The window that received the mouse evenents
theta	The azimuth (or azimuthal angle) measured from the azimuth reference direction to the orthogonal projection of the line segment \(OP\) on the reference plane
phi	The inclination (or polar angle) between the zenith direction and the line segment \(OP\)
radius	The radial distance of the camera to origin, i.e. the Euclidian distance between \(O\) and \(P\)
turnSpeed	The rotation speed
scrollSpeed	The zoom speed
panSpeed	The panning speed
