Heightfield Clip Vertical

Node Description and Purpose:
The Heightfield Clip Vertical node can be used to cut off high or low points of a heightfield. This has the effect of creating plateaus and plains from the clipped areas.


Node Type: Heightfield Operator


Settings:

  • Clip peaks: If this is checked then all parts of the heightfield above the specified height are cut off at that height. For example all parts of the heightfield above 100m are set to 100m.
  • Clip valleys: If this checkbox is checked all parts of the heightfield below the specified height are raised up to that height. As an example, all parts of the heightfield below 0m are raised up to 0m.

A heightmap or heightfield is an array of height values, usually in a grid which describe the height at specific points in a defined area. Heightfields are used to represent real-world and virtual terrain in a specific, easily converted format. Most heightfields can be represented as simple image data in grayscale, with black being minimum height and white being maximum height.
