Detailed Description

Implements the camera movement with user input.

Constructor & Destructor Documentation

Camera::Camera	(	const std::string &	name,
		Scene *	scene,
		const glm::vec3 &	eye = glm::vec3(0, -10, 5),
		float	vAngle = -3.14f,
		float	hAngle = 3.14f,
		float	fov = 60.0f,
		float	near = 0.01f,
		float	far = 20.0f
	)

Construct new camera.

The camera is a SceneObject, but it has also a view matrix. The computation of the view matrix is done from the horizontal and vertical angles of the camera. From these Spherical coordinates the Cartesian coordinates are computed, these are the direction and the right vector. The cross product of this two vector gives the up vector. Then using the glm::lookAt function, the view matrix is computed. The camera has a projection matrix. On zooming this projection matrix is recomputed using the glm::perspective function. When an object is being rendered, the view matrix of the camera is returned.
