Reasonable values on the scene extends hence have to be provided to the QGLViewer - in order for the Camera to correctly display the scene. High level positioning methods also use - this information (showEntireScene(), centerScene()...). - - A Camera holds KeyFrameInterpolator that can be used to save Camera positions and paths. You can - interactively addKeyFrameToPath() to a given path using the default \c Alt+F[1-12] shortcuts. Use - playPath() to make the Camera follow the path (default shortcut is F[1-12]). See the <a - href="../keyboard.html">keyboard page</a> for details on key customization. - - Use cameraCoordinatesOf() and worldCoordinatesOf() to convert to and from the Camera frame() - coordinate system. projectedCoordinatesOf() and unprojectedCoordinatesOf() will convert from - screen to 3D coordinates. convertClickToLine() is very useful for analytical object selection. - - Stereo display is possible on machines with quad buffer capabilities (with Camera::PERSPECTIVE - type() only). Test the <a href="../examples/stereoViewer.html">stereoViewer example</a> to check. - - A Camera can also be used outside of a QGLViewer or even without OpenGL for its coordinate system - conversion capabilities.

The order of - these transformations is important: the Frame is first translated \e and \e then rotated around - the new translated origin. - - A Frame is useful to define the position and orientation of a 3D rigid object, using its matrix() - method, as shown below: - \code - // Builds a Frame at position (0.5,0,0) and oriented such that its Y axis is along the (1,1,1) - // direction. One could also have used setPosition() and setOrientation(). - Frame fr(Vec(0.5,0,0), Quaternion(Vec(0,1,0), Vec(1,1,1))); - glPushMatrix(); - glMultMatrixd(fr.matrix()); - // Draw your object here, in the local fr coordinate system. - glPopMatrix(); - \endcode - - Many functions are provided to transform a 3D point from one coordinate system (Frame) to an - other: see coordinatesOf(), inverseCoordinatesOf(), coordinatesOfIn(), coordinatesOfFrom()... - - You may also want to transform a 3D vector (such as a normal), which corresponds to applying only - the rotational part of the frame transformation: see transformOf() and inverseTransformOf(). See - the <a href="../examples/frameTransform.html">frameTransform example</a> for an illustration. - - The translation() and the rotation() that are encapsulated in a Frame can also be used to - represent a \e rigid \e transformation of space. Such a transformation can also be interpreted as - a change of coordinate system, and the coordinate system conversion functions actually allow you - to use a Frame as a rigid transformation. Use inverseCoordinatesOf() (resp. coordinatesOf()) to - apply the transformation (resp. its inverse). Note the inversion. - - <h3>Hierarchy of Frames</h3> - - The position and the orientation of a Frame are actually defined with respect to a - referenceFrame(). The default referenceFrame() is the world coordinate system (represented by a \c - NULL referenceFrame()). If you setReferenceFrame() to a different Frame, you must then - differentiate: - - \arg the \e local translation() and rotation(), defined with respect to the referenceFrame(), - - \arg the \e global position() and orientation(), always defined with respect to the world - coordinate system. - - A Frame is actually defined by its translation() with respect to its referenceFrame(), and then by - a rotation() of the coordinate system around the new translated origin. - - This terminology for \e local (translation() and rotation()) and \e global (position() and - orientation()) definitions is used in all the methods' names and should be sufficient to prevent - ambiguities. These notions are obviously identical when the referenceFrame() is \c NULL, i.e. when - the Frame is defined in the world coordinate system (the one you are in at the beginning of the - QGLViewer::draw() method, see the <a href="../introduction.html">introduction page</a>). - - Frames can hence easily be organized in a tree hierarchy, which root is the world coordinate - system. A loop in the hierarchy would result in an inconsistent (multiple) Frame definition. - settingAsReferenceFrameWillCreateALoop() checks this and prevents setReferenceFrame() from - creating such a loop. - - This frame hierarchy is used in methods like coordinatesOfIn(), coordinatesOfFrom()... which allow - coordinates (or vector) conversions from a Frame to any other one (including the world coordinate - system). - - However, one must note that this hierarchical representation is internal to the Frame classes. - When the Frames represent OpenGL coordinates system, one should map this hierarchical - representation to the OpenGL GL_MODELVIEW matrix stack. See the matrix() documentation for - details. - - <h3>Constraints</h3> - - An interesting feature of Frames is that their displacements can be constrained. When a Constraint - is attached to a Frame, it filters the input of translate() and rotate(), and only the resulting - filtered motion is applied to the Frame. The default constraint() is \c NULL resulting in no - filtering. Use setConstraint() to attach a Constraint to a frame. - - Constraints are especially usefull for the ManipulatedFrame instances, in order to forbid some - mouse motions. See the <a href="../examples/constrainedFrame.html">constrainedFrame</a>, <a - href="../examples/constrainedCamera.html">constrainedCamera</a> and <a - href="../examples/luxo.html">luxo</a> examples for an illustration. - - Classical constraints are provided for convenience (see LocalConstraint, WorldConstraint and - CameraConstraint) and new constraints can very easily be implemented. - - <h3>Derived classes</h3> - - The ManipulatedFrame class inherits Frame and implements a mouse motion convertion, so that a - Frame (and hence an object) can be manipulated in the scene with the mouse. - - \nosubgrouping */ - class Frame - { - - public: - Frame(); - - /*!

A ManipulatedFrame is - used to move an object in the scene.

The powerful coordinate system - transformation functions (Frame::coordinatesOf(), Frame::transformOf(), ...) can hence be applied - to a ManipulatedFrame. - - A ManipulatedFrame is also a MouseGrabber. If the mouse cursor gets within a distance of 10 pixels - from the projected position of the ManipulatedFrame, the ManipulatedFrame becomes the new - QGLViewer::mouseGrabber().

If you want to move several objects - in the scene, you simply have to keep a list of the different ManipulatedFrames, and to activate - the right one (using QGLViewer::setManipulatedFrame()) when needed.
