Free View
SPL is mapped onto each surface area, viewed in 3D. Users can manipulate the exact
vantage point by using the mouse in combination with keyboard. In this mode, it is
possible to zoom in or out, as well as to ‘orbit’ a center point in 3D by clicking and
dragging. By holding the “Shift” key while clicking and dragging, this point can be shifted
around the X-Y (horizontal) plane.
In all three views, the user can zoom in or out by using the toolbar buttons or the scroll
wheel on the mouse (if the computer is so equipped). Additionally, the X, Y, and Z axes
are color-coded (X is red, Y is green, Z blue) and labeled with text in all three views for
easy identification.
SPL Scale
On the right side of all three view modes, the SPL scale is displayed. Values range from
low (bottom, dark blue) to high (top, bright red). The limits of the scale and therefore
the resolution (dB of change per color change) are variable, however. To automatically
set the range of the scale to the range of SPL in the current prediction, the user may
use the “Auto-Adjust SPL Range” function (under the “Options” menu, or by pressing
“A” with default keyboard shortcuts). For manual control, single-click on the SPL scale.
