OrbitOperator

class HPS::OrbitOperator : public HPS::Operator

The OrbitOperator class defines an operator which allows the user to orbit the camera. This Operator works for both mouse- and touch-driven devices. Mouse-Driven Devices: Left button pressed and move: Orbit camera Touch-Driven Devices: Touch down and move: Orbit camera

Public Functions

inline virtual HPS::UTF8 GetName() const

Returns the name of the operator.

virtual bool OnMouseDown(MouseState const &in_state)

This function is called whenever HPS receives a MouseEvent that signals a mouse button was pressed. This function starts the operator and computes the position of the starting point.

Parameters

in_state – A MouseState object describing the current mouse state.

Returns

true if the input event was handled, false otherwise.

virtual bool OnMouseMove(MouseState const &in_state)

This function is called whenever HPS receives a MouseEvent that signals the mouse moved This function orbits the camera as needed.

Parameters

in_state – A MouseState object describing the current mouse state.

Returns

true if the input event was handled, false otherwise.

virtual bool OnMouseUp(MouseState const &in_state)

This function is called whenever HPS receives a MouseEvent that signals a mouse button was released. This function stops the operator.

Parameters

in_state – A MouseState object describing the current mouse state.

Returns

true if the input event was handled, false otherwise.

virtual bool OnTouchDown(TouchState const &in_state)

This function is called whenever HPS receives a TouchEvent that signals the device was touched. This function starts the operator and computes the position of the starting point.

Parameters

in_state – A TouchState object describing the current touch state.

Returns

true if the input event was handled, false otherwise.

virtual bool OnTouchMove(TouchState const &in_state)

This function is called whenever HPS receives a TouchEvent that signals a point of contact has moved. This function orbits the camera as needed.

Parameters

in_state – A TouchState object describing the current touch state.

Returns

true if the input event was handled, false otherwise.

virtual bool OnTouchUp(TouchState const &in_state)

This function is called whenever HPS receives a TouchEvent that signals a point of contact has been released. This function stops the operator.

Parameters

in_state – A TouchState object describing the current touch state.

Returns

true if the input event was handled, false otherwise.
