<hr><a name="_details"></a><h2>Detailed Description</h2>
A <a class="el" href="classqglviewer_1_1Camera.html">Camera</a> <a class="el" href="classqglviewer_1_1Frame.html">Frame</a> that can be rotated and translated with the mouse.
<p>
A <a class="el" href="classqglviewer_1_1ManipulatedCameraFrame.html">ManipulatedCameraFrame</a> is a specialization of a <a class="el" href="classqglviewer_1_1ManipulatedFrame.html">ManipulatedFrame</a>, designed for associated <a class="el" href="classqglviewer_1_1Camera.html">Camera</a> frames. All mouse motions are basically interpreted in a negated way: when the mouse goes to the right, the <a class="el" href="classqglviewer_1_1ManipulatedFrame.html">ManipulatedFrame</a> translation goes to the right, while the <a class="el" href="classqglviewer_1_1ManipulatedCameraFrame.html">ManipulatedCameraFrame</a> has to go to the <em>left</em>, so that the <em>scene</em> seems to move to the right.<p>
See the <a href="../mouse.html">mouse page</a> for a description of the possible displacements that can be performed using the mouse.<p>
The <a class="el" href="classqglviewer_1_1ManipulatedFrame.html#z69_0">ManipulatedFrame::isManipulated()</a> function is used to call <a class="el" href="classQGLViewer.html#b7">QGLViewer::fastDraw()</a> instead of <a class="el" href="classQGLViewer.html#b6">QGLViewer::draw()</a> for interactive scene displays when the camera is manipulated (see the <a href="../examples/fastDraw.html">fastDraw</a> example).<p>
A <a class="el" href="classqglviewer_1_1ManipulatedCameraFrame.html">ManipulatedCameraFrame</a> can be used as the <a class="el" href="classQGLViewer.html#z89_1">QGLViewer::manipulatedFrame()</a> (for instance, with two viewers, it is possible to manipulate the first viewer camera is the second viewer). In that case, the mouse response will be the one of a <a class="el" href="classqglviewer_1_1ManipulatedFrame.html">ManipulatedFrame</a>, as one would expect.<p>
<a class="el" href="classqglviewer_1_1ManipulatedCameraFrame.html">ManipulatedCameraFrame</a> are not automatically added to the <a class="el" href="classqglviewer_1_1MouseGrabber.html#z79_4">MouseGrabber::MouseGrabberPool()</a> as <a class="el" href="classqglviewer_1_1ManipulatedFrame.html">ManipulatedFrame</a> are.

The wheel behavior depends on the wheel binded action. Current possible actions are ZOOM, MOVE_FORWARD, MOVE_BACKWARD. See <a class="el" href="classQGLViewer.html#z107_9">QGLViewer::setWheelBinding()</a> to customize the binding.<p>
ZOOM speeds depends on <a class="el" href="classqglviewer_1_1ManipulatedFrame.html#z67_3">wheelSensitivity()</a> while MOVE_FORWARD and MOVE_BACKWARD depend on <a class="el" href="classqglviewer_1_1ManipulatedCameraFrame.html#z61_0">flySpeed()</a>.<p>
Depending on your system configuration, you may have to actually <em>press</em> the wheel while wheeling.
