Public Methods

Method	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

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

Method Details

Camera() public method

Creates a camera with specified values.

public Camera ( Device graphicsDevice, System.Vector3 position, System.Vector3 look, float nearPlane, float farPlane ) : System
graphicsDevice	Device	Virtual adapter used to perform rendering.
position	System.Vector3	Position of a camera.
look	System.Vector3	A point the camera look at.
nearPlane	float	A near plane of a camera frustum.
farPlane	float	A far plane of a camera frustum.
return	System

FixVectors() public method
