7.1. Interaction Scheme

The basic interaction scheme is a mouse-based interaction. The application is best run using a two-button mouse with a scroll wheel. In the most recent version of Corelyzer, the mouse clicks and events are context sensitive. This means, depending on what your mouse pointing to, the response of the application to mouse events can vary.

7.1.1. Panning

To automatically begin panning using the Click-and-drag style, first left-click on the visualization window, making sure not to click on any objects (e.g. core section images, graphs, annotation markers, etc.)

If you successfully clicked and are in the panning-mode, then the mouse pointer should change. In Windows, it will likely change to a four-direction pointer. On Mac OS X, it will change from a black mouse to a white mouse cursor. To pan, keep holding down the left mouse button and drag the mouse to move the view of the scene.

7.1.2. Zooming

If you have a mouse wheel, zooming is as easy as scrolling the wheel back to zoom out and forward to zoom in. Assuming a particular area is of interest and you want to zoom in on it, simply point at that area of interest and use the mouse wheel to zoom in. The area will stay in the same place as the scene changes in scale. Similarly, you can zoom out to see more of the context that surrounds a particular area.

You can also use keyboard for navigation in Corelyzer. You can use the four-direction arrow key to pan around the main visualization area. To zoom in and out around the mouse cursor position, you can press the "+" and "-" keys. If you want to jump to a certain depth directly, first click on the main visualization area and then press the "j" key to bring up the "Jump to..." dialog. Input the depth in meter and the main visualization area will jump to designated depth directly.

7.1.3. Sliding a section

To slide a section image, first left-click on the section image, the image will be highlighted by a yellow bounding box. If you successfully do this, the mouse pointer will change to a hand pointer. The core section image will also be brought to the front of the other images. This is noticeable if any of the core section images overlap. At this point you can slide the section image left or right by moving your mouse left or right with Alt key pressed at the same time.

7.1.4. Sliding a track

A track can be slid vertically. To do this, first select a core section image, and then hold down the Shift key. The mouse pointer will remain looking like a hand cursor. Move the mouse up or down and the track will be moved in the direction of the mouse motion.

NOTE: Corelyzer loads all images and tracks at the origin. It is recommended to slide a track away so that new images on a different track do not overlap an existing track.
