camera_controller_orbit_euler

Mouse and keyboard control of a camera_orbit_euler (default camera of the scene template).

Derives from: camera_controller_generic_base

Fields and methods

Members of the struct camera_controller_orbit_euler. Most of what you do with a CGP type goes through the free functions listed below.

camera_orbit_euler camera_model Euler-angle orbit camera driven by the controller.

`camera_generic_base const& camera() const` `camera_generic_base& camera()`	Returns camera_model as a read-only camera_generic_base. src
`void set_rotation_axis(vec3 const& rotation_axis)`	Sets the axis_of_rotation (up direction of the orbit) of the camera. src
`void set_rotation_axis_x()`	Sets the axis_of_rotation of the camera to (1,0,0). src
`void set_rotation_axis_y()`	Sets the axis_of_rotation of the camera to (0,1,0). src
`void set_rotation_axis_z()`	Sets the axis_of_rotation of the camera to (0,0,1). src
`void look_at(vec3 const& eye, vec3 const& center, vec3 const& unused = vec3())`	Places the camera at eye looking toward center; the third argument is ignored (the up vector is set by axis_of_rotation). src
`void action_mouse_move()`	Updates the camera from the mouse displacement when the cursor is not on the GUI; left drag changes pitch and yaw, Ctrl + left drag pans, right drag (or K + left drag) changes the distance to the center, Ctrl + right drag translates the center front/back. src
`void idle_frame()`	Twists axis_of_rotation at 2 radians per second while Shift + left/right arrow (or Shift + R/F) is held. src
`std::string doc_usage() const`	Returns a text describing the mouse and keyboard controls of the Euler orbit camera. src

Inherited from camera_controller_generic_base (6 members)

`bool is_active = true`	Enables the controller, true by default; when false the mouse and idle actions return without moving the camera.
`input_devices* inputs = nullptr`	Pointer to the global keyboard/mouse state, nullptr until initialize() is called.
`window_structure* window = nullptr`	Pointer to the global window state, nullptr until initialize() is called.

`void initialize(input_devices& inputs, window_structure& window)`	Stores pointers to the global inputs and window; must be called before any action function. src
`void action_keyboard()`	Handles a keyboard press or release event; does nothing in the base class. src
`void action_mouse_click()`	Handles a mouse button press or release event; does nothing in the base class. src
