Chapter 12: Creating 3D Views Using GridView
User Guide

The Grid section enables you to set the display characteristics of the highlighted grid file.
• The Transparency slider bar enables you to set the degree of transparency the highlighted grid
will have. With the slider bar set fully to the right, the grid will display normally. As the slider bar is
moved to the left, the grid will begin to vanish into the background. This can be particularly
effective when you want to view two grids in the same scene, both with varying amounts of
transparency. When the slider bar is selected (indicated by the dashed line around it), the arrow
keys can be used to modify the degree of transparency.
• The Draw Underside check box enables you to render the underside of the highlighted grid.
This is useful when the viewing location is set below the surface of the grid and the viewer is
looking up from under the grid surface. When this option is set, the scene will render more
slowly.
• The Preview Resolution slider bar enables you to set the degree of resolution for the preview
window. When the slider bar is selected (indicated by the dashed line around it), the arrow keys
are used to modify the degree of resolution. Although grids are rendered faster at lower
resolutions, they have far less detail. With some grids, the resolution can be increased to a
degree that proves to be extremely inefficient. If this occurs a warning message appears giving
you the opportunity to abort the setting modification.
