Quadtree UGrid Functional Surface Options.

Functional Surfaces Options dialog

To create/display functional surfaces, enable them in the display options of the appropriate module, and specify their attributes which include:

• Dataset – Selects which dataset is to be used to form the functional surface.

• Use active dataset
• User defined dataset

• Z Offset – SMS displays functional surfaces at a simulated z-value. This may be the actual surface value (such as is the case with water surfaces elevations), but more often the value will not have a physical meaning, and may intersect the bathymetry or not even be in the same area. For this reason, SMS offers options for placing the functional surface at one of the following locations:
  • "Display surface at location"
  • "Display surface above geometry"
  • "Display surface with user defined offset"
• Z Magnification – Functional data may not vary significantly when compared to the horizontal extents of the model. For this reason, the interface allows magnification (scaling) of the functional surface. By default, the surface is scaled based on the global z-magnification specified in the general display options. This may be overridden.

• Override global value
• Magnification value

• Display Attributes – Controls the color of the functional surface. It may be a constant color or colored based on the contour colors specified. The colors may be associated with the value of the functional surface, or another dataset. The surface may also be partially transparent.

• Use solid color
• Transparency
• Contour surface
• Specify separate dataset for contours
