Interacting with 3D Views

Once you have launched a 3D View from the Region Views, Index, or Bone Views section, you can interact with it in a number of ways. Use the mouse, on-screen controls, or the keyboard to interact with the 3D models.

 

Pan:

Mouse: While holding down the spacebar, click on part of the model and drag to move it vertically, horizontally, or diagonally.

Screen controls: Click on the arrow buttons around the virtual joystick to move the model in the indicated direction.

Keyboard: Press W to pan the camera up, S to pan down, A to pan left, and D to pan right.

 

Rotate or tilt:

Mouse: Click and drag the 3D model to rotate it in the direction the mouse is moved.

Screen controls: Click and drag the virtual joystick to rotate the 3D model in the direction the joystick is moved.

Keyboard: Use the keyboard arrow keys to rotate the camera around the 3D model in the desired direction.

 

Zoom in or out:

Mouse: Spin the mouse wheel to adjust the zoom level.

Screen controls: Drag the on-screen zoom slider to adjust the zoom level.

Keyboard: Hold + on the keyboard to zoom in, or hold - to zoom out.

 

Center a specific structure: Double-click on a structure to center it in the middle of the screen at an appropriate zoom level. This structure now becomes the pivot point as you rotate the 3D model.

Refresh View: Click the name of the View located at the top left corner or the screen to return it to its initial state. Alternatively, you can click on the "Previous View" button in the Tools menu.

Background Color: Click on the black and white squares at the top of the screen (to the left of the logo) to toggle between a white or black background for your View.

Full Screen: Click the arrows icon at the top of the screen to hide the onscreen interface and enter full screen mode. When toolbars are hidden, use the keyboard controls to rotate, zoom, tilt, click to select, and show/fade/hide. To return to the regular interface, click the arrows icon again.

 

Select and deselect structures onscreen:

Select a single structure: Click on an anatomical structure to select it. The structure is highlighted and a breadcrumb trail appears at the top of the screen, displaying hierarchical information about the structure, including its name (highlighted as the last term to the right). A second selection overrides the first selection (unless in Multiple Select mode; see below), so that only one structure at a time is highlighted. To deselect a selected structure, click on it once.

Select multiple structures: While holding down the Shift key, click on each of the structures in the 3D model you wish to select. You can also click on the "Multiple Select" button under the joystick. The Multiple Select mode allows you to select as many structures as you wish by clicking each structure once. All remain highlighted, but only the most recently selected structure selected is displayed in the breadcrumb trail at the top of the screen. To deselect any selected structure, click on it once. To return to Single Select mode, click on the on-screen "Single Select" button.

Select a related group of structures: When any anatomical structure is selected, a breadcrumb trail appears at the top of the screen displaying hierarchical information about the structure. To select any of the larger groupings, click once on the desired name in the breadcrumb trail. The associated anatomical structures are added to the model if necessary, selected, and highlighted onscreen.

Select through faded structures: While holding down the T key, click on a structure visible through a faded (transparent) structure to select it.

Deselect structures: If Multiple Select mode is on, deselect a single structure by clicking on it again, or deselect all structures by clicking on the on-screen "Deselect All" button. If Single Select mode is on, click on a background area of the screen to deselect a single structure, or click on the selected structure itself.

 

Show, hide, and fade structures onscreen:

 

Fade selected structure(s):

Screen controls: Click on the "Fade" button.

Keyboard: Press the V key to toggle selected structure(s) from showing to faded and back again.

 

Hide selected structure(s):

Screen controls: Click on the "Hide" button. You can click on the "Show" button to return the structure to the view as long as it is still selected.

Keyboard: Press the H key to toggle selected structure(s) from showing to hidden and back again.

 

Hide all unselected structures:

Screen controls: Click on the "Hide others" button in the Tools menu with the desired structure(s) selected to make all other structures hidden.

Keyboard: Press the O key with the desired structure(s) selected to make all other structures hidden.

 

Fade all unselected structures:

Click on the "Fade Others" button in the Tools menu with the desired structure(s) selected to make all other structures faded (transparent). If no structure is selected, the "Fade Others" button makes all of the structures on screen transparent.

 

Show all structures:

Show all faded or hidden structures in the original View (along with any others you may have added to it) by clicking the "Show All" button in the Tools menu.
