Public Member Functions
	OrthographicCamera (GLfloat minX=-1.0f, GLfloat maxX=1.0f, GLfloat minY=-1.0f, GLfloat maxY=1.0f, GLfloat minZ=-1.0f, GLfloat maxZ=1.0f)
	initializes the OrthographicCamera
Public Member Functions inherited from CSCI441::Camera
virtual	~Camera ()=default
	properly destroy concrete children
virtual void	recomputeOrientation ()=0
	Uses theta, phi, & radius to update the camera's view matrix parameters. The camera orientation is controlled via spherical coordinates and this method would orient and/or position the camera in cartesian coordinates.
virtual void	moveForward (GLfloat movementFactor)=0
	steps forward along the camera's view
virtual void	moveBackward (GLfloat movementFactor)=0
	steps backward along the camera's view
virtual void	rotate (GLfloat dTheta, GLfloat dPhi)
	rotates the camera's POV by adding to theta & phi then ensuring phi stays within the (0, pi) range and finally calls through to recomputeOrientation() to update the view parameters after the rotation
virtual void	computeViewMatrix () final
	creates the View Matrix based on the position, lookAt point, and up vector
virtual glm::mat4	getProjectionMatrix () const final
	returns the current projection matrix for the associated camera
virtual glm::mat4	getViewMatrix () const final
	returns the current view matrix for the associated camera
virtual glm::vec3	getPosition () const final
	returns the current camera position in world space
virtual glm::vec3	getLookAtPoint () const final
	returns the current lookAt point in world space
virtual glm::vec3	getUpVector () const final
	returns the current up vector in world space
virtual GLfloat	getTheta () const final
	returns the current theta value in radians
virtual GLfloat	getPhi () const final
	returns the current phi value in radians
GLfloat	getRadius () const
	returns the current radius in world space
virtual void	setPosition (const glm::vec3 pos) final
	sets the camera's position in world space
virtual void	setLookAtPoint (const glm::vec3 lookAt) final
	sets the camera's lookAt point in world space
virtual void	setUpVector (const glm::vec3 up) final
	sets the camera's up vector in world space
virtual void	setTheta (const GLfloat t) final
	sets the camera's theta angle in radians
virtual void	setPhi (const GLfloat p) final
	sets the camera's phi angle in radians
virtual void	setRadius (const GLfloat r) final
	sets the camera's radius in world space

	Camera ()
	create a default camera at the origin, looking down the negative Z axis oriented with the world coordinate system
Protected Attributes inherited from CSCI441::Camera
glm::mat4	mProjectionMatrix
	stores the Projection Matrix
glm::mat4	mViewMatrix
	stores the View Matrix corresponding to the inverse of the Camera's Matrix
