Méthodes publiques

Méthode	Description
Camera ( Device graphicsDevice, System.Vector3 position, System.Vector3 look, float nearPlane, float farPlane ) : System	Creates a camera with specified values.
FixVectors ( ) : void	Fixes camera sphere point and look vector. Sphere point is fixed by camera look vector spherical unmapping. Look vector is fixed by putting it at a distance of one unit away from position vector.
MoveLook ( System.Vector2 mousePositionDelta, float speed ) : void	Moves camera look vector around a sphere.
MovePosition ( MoveDirection moveDirection, double deltaTime ) : void	Moves a camera position vector.
UpdateProjection ( ) : void	Updates camera projection matrix.

Private Methods

Méthode	Description
ExtractPlanesFromFrustum ( ) : void	Computes plane equations used in frustum culling.
UpdateView ( ) : void	Updates camera view matrix.
