Feel the Flare

Put a grouped level rectangle in the middle of a big dramatically sloping terrain plot, so it partly sticks into the slope.

Select the rectangle, and Run Fit. Now, run ::Flare:.

To explore what Flare does, experiment with the four parameters in the VCB. Start with low-percent Slopes, a long length, and Direction 1.

What does the Direction Parameter Mean?

It controls whether to move terrain upwards-and-downwards, downwards-only, or upwards-only. Also see the Panel..

Outwards or Inwards?

If you blend an closed path, for instance a circle, what is outwards is clear. Now, if you remove one segment from the circle, it is still quite clear what is outwards, even though it is now a an open path.

If you blend an open path, Landshape will try to determine what is outwards and inwards by the convexity of the path.

If you blend a single straight path (which lacks a convex/concave distinction), Landshape will interpret outward as towards the camera.
