__NOTITLE__

= Working with the QtCoin GUI =

The GUI is very simple, but it still allows you to interactive move the camera and objects. The first thing to note is that there are two modes of control: camera control and object control. Press '''ESC''' to toggle between the two. Selecting an object makes it transparent and renders 3 arrows to represent the transformation of the object (red, green, and blue correspond to +X, +Y, and +Z axes respectively, the origin is the point where all axes meet).

== Camera Mode ==
* Left mouse button - hold to rotate
* Middle mouse button - pan camera
* Left+Middle mouse buttons, or scroller - zoom camera
* Press '''s''' and click on any part of the scene to zoom in on it. The camera now centers on that object when rotating.

== Object Interaction Mode ==
* Left mouse button - Select object. A green wire-frame of a box will pop up. The object can then be moved around a 2D plane using the left mouse button. If the edges of the box are clicked on, the box will rotate instead of translate.

* Ctrl+Left mouse button (Command+Left mouse button on OS X) - Use to select joints of an object. A green thin cylinder will pop up, click on it to move the joint. Use Ctrl+click (Command+click on OS X) to drag the cylinder in order to make it bigger or smaller. When a joint is selected the effected link will change color.
