Enumeration Type Documentation

enum vizkit3d::CAMERA_MANIPULATORS

The list of available camera manipulators

IMPORTANT: if you change this, you MUST edit the KNOWN_MANIPULATORS array in Vizkit3DWidget.cpp as well !

Enumerator
DEFAULT_MANIPULATOR	Wheel controls forward/backward movement, in the direction of the camera. Left button + mouse movement controls pitch and yaw. Right button + mouse movement pans. The value given to setWheelMovement is the scale factor between the wheel movement and the actual movement in the scene. It defaults to 0.05. There is also a way to force centering the camera on the current mouse pointer position whenever the wheel is used by giving the SET_CENTER_ON_WHEEL_FORWARD_MOVEMENT flag to the constructor. The centering is animated (i.e. not abrupt) and the animation step is controlled by setAnimationTime If vertical axis is fixed (the default), the rotation maintain the "up" vector. Otherwise, they don't. It can be changed with setVerticalAxisFixed.
FIRST_PERSON_MANIPULATOR	Wheel controls forward/backward movement, in the direction of the camera. Left button + mouse movement controls pitch and yaw. The value given to setWheelMovement is the scale factor between the wheel movement and the actual movement in the scene. It defaults to 0.05. There is also a way to force centering the camera on the current mouse pointer position whenever the wheel is used by giving the SET_CENTER_ON_WHEEL_FORWARD_MOVEMENT flag to the constructor. The centering is animated (i.e. not abrupt) and the animation step is controlled by setAnimationTime If vertical axis is fixed (the default), the rotation maintain the "up" vector. Otherwise, they don't. It can be changed with setVerticalAxisFixed.
FLIGHT_MANIPULATOR	Behaves like a flight simulator controlled by a mouse. The position of the mouse w.r.t. the center of the window causes pitch/roll. By default (can be turned off), yaw is also changed if the camera banked (has non-zero roll). In addition, the camera has a velocity and moves continuously if this velocity is non-zero. The left mouse button causes the camera's velocity to grow, the right mouse to decrease and the middle mouse button sets it to zero.
ORBIT_MANIPULATOR	Transforms the camera as if it was "orbiting" a point of reference (the camera center). The mouse wheel applies a scale factor on the distance between the camera eye and the center, as 1.0 + wheelZoomFactor (regardless of the actual wheel movement). The default wheelZoomFactor is 0.1. If this distance becomes smaller than a minimum distance (defaults to 0.05), the center gets "pushed" forward so that the minimum distance is kept. In practice, it means that the wheel movement is huge when far from the center and tiny when close. Moving the mouse with the left mouse button pressed does a trackball rotation, i.e. makes the camera move "as if" the mouse moved a sphere centered on the center point. By default, the orbit manipulator constrains the vertical axis to keep within the same plane (i.e. vertical is always vertical) Moving the mouse with the right mouse button pressed also applies a zoom (following the same rules). The scale factor applied is the movement in Y, 1.0 seems to be the whole height of the window. Moving the mouse with the middle mouse button pressed applies a panning movement. The movement is displacement * 0.3 * distance_to_center
TERRAIN_MANIPULATOR	Like an orbit manipulator, with the middle-button behaviour changed If the mouse is moved while the middle button is pressed, X movement moves the center in the camera's side direction and Y movement moves it in the forward direction. The movement in each case is 0.3 * distance_to_center * distance_moved. In addition, if a node is associated with the camera, the center will "track" the node's shape, i.e. an intersection is computed and the distance-to-node kept.
TRACKBALL_MANIPULATOR	Just like an orbit manipulator, but with the fixed-vertical-axis constraint set to false by default
MULTI_TOUCH_TRACKBALL_MANIPULATOR	Like the trackball manipulator, but reacts to pinch-to-zoom vs. drag multitouch events.
NODE_TRACKER_MANIPULATOR	Tracks a node. This cannot be set with setCameraManipulator, as the manipulator requires special setup. It is used internally by setVisualizationFrame and setTrackedNode
NO_MANIPULATOR	No manipulator
