Clipping Terrains
Using the Terrain Editor's clipping controls, you determine which values in your terrain are rendered as the final terrain object. The Clipping controls next to the Gradient bar represent the render range for the terrain. Anything outside the range included in the brackets will not be rendered.
You can use these controls to eliminate unwanted information from the terrain without altering its basic shape. For example, you can keep the main terrain while eliminating the black square on which it sits.
The clipping feature is particularly useful when editing a Symmetrical Lattice. The maximum lower range of the Clipping Bracket determines where the two halves of the Symmetrical Lattices are joined.
To set the clipping range:
1 Drag the top of the Clipping Bracket to set the maximum upper range.
Any areas in the Terrain Canvas whose gray levels fall outside the bracket's maximum upper range will appear colored to indicate they will be omitted from rendering.
2 Drag the bottom of the Clipping Bracket to set the maximum lower range.
Any areas in the Terrain Canvas whose gray levels fall outside the bracket's maximum lower range will also appear colored to indicate they will be omitted from rendering.
The out-of-range colors for upper and lower limits are different, to better enable you to distinguish upper and lower clipped areas at a glance. Upper out-of-range color is usually yellow, and lower out-of-range is usually red, though the colors change for many of the color maps.
To reset the Clipping Bracket:
To move the entire Clipping Bracket at once:
Terrain objects are hollow, so if you clip the upper range off your terrain, you'll be able to see through the top of the terrain to whatever is underneath. To make the top solid, you should select Solid from the drop-down menu at the top right of the Terrain Canvas.
