OrbitControl is a camera controller that allows orbiting a center point while looking at it.

func NewOrbitControl

func NewOrbitControl(icam camera.ICamera, win window.IWindow) *OrbitControl

NewOrbitControl creates and returns a pointer to a new orbito control for the specified camera and window

func (*OrbitControl) Dispose

func (oc *OrbitControl) Dispose()

Dispose unsubscribes from all events

func (*OrbitControl) Pan

func (oc *OrbitControl) Pan(deltaX, deltaY float32)

Pan the camera and target by the specified deltas

func (*OrbitControl) Reset

func (oc *OrbitControl) Reset()

Reset to initial camera position

func (*OrbitControl) RotateLeft

func (oc *OrbitControl) RotateLeft(angle float32)

RotateLeft rotates the camera left by specified angle

func (*OrbitControl) RotateUp

func (oc *OrbitControl) RotateUp(angle float32)

RotateUp rotates the camera up by specified angle

func (*OrbitControl) Zoom

func (oc *OrbitControl) Zoom(delta float32)

Zoom in or out
