Velocity Banners

The Velocity Banner feature is accessed from the Viewing Options in View3D. Effectively this displays the 3-D velocities in a profile for each cell, something like a "wind sock", which may be colored by depth or magnitude. A pole runs between the bottom and water surface from which the velocity profiles face in different directions as shown in Figure 1.

The user may fix the color of the banner using the Display Options | 3D View tab | 3D Color Ramp Options.

Figure 1  View3D: Velocity Profiles.

The user should navigate to Display Options | 3D View | Velocity Banner Options tab to set where the profiles begin and set the frequency that they are displayed on the grid. The user may also set the color of the pole and pole thickness as shown in Figure 2.

As in the ViewPlan for 2D plan view, the Velocity Profile setting allows the user to define where to start and end the profiles as well as set the skip function to skip a certain number of cells. The user may also use the Velocity Labeling Locations File which will set the points for display. Velocities will only display at the locations set in the file.
