If you have a question you'd like us to address in Function Junction, please send us an
email and we'll do our best to address it in the next issue.
This month we are going to explore the functionality available in our PDT 3D Prototype demo. If you
are like us and never read instructions this one is going to challenge you. Take a minute to read the
following tips and then have some fun with the latest in PDT.
Since this is a prototype, your comments are extremely important to us. Good, bad, or inquisitive, we
really want to hear from you. Please take a few seconds to email us
and tell us your thoughts on PDT 3D.
Using the PDT 3D Directional Controls
STEP 1: ACCESS THE DIRECTIONAL CONTROLS
Hold down the control key to make the Directional Control Toolbar appear at the bottom of the image.
STEP 2: ALTER YOUR VIEW OF THE MODEL

To use the directional controls:
- Hold down the Control Key ("Ctrl") on your keyboard
- Position the cursor over the desired control ("Pan", "Rotate", or "Zoom")
- Press and hold the left mouse button and move your mouse to obtain the desired movement of the model
around the area of interest (Target)
Pan - Standard panning functionality
Rotate - Rotate the cube and see your target from any angle
Zoom - Standard zooming functionality
STEP 3: SELECTING A NEW AREA OF INTEREST (or TARGET)
Choose a New Target by aligning your cursor over the cube of interest, and press the center mouse button.
This will highlight the cube red.
STEP 4: MANIPULATING THE PDT LENS
Manipulate the Lens using the lens' translucent MDLC control handles and slider. The depth of view (lens
depth), magnification in the focal region, and size can be interactively manipulated using the sliding bar
controls. The position of the lens can be moved by clicking and dragging.
Change the Depth of Target Plane by using the sliders along the right side and bottom of the lens.
Adjust the Size of the Lens' focal region and base by clicking and dragging the respective handles to re-size.
