Overview

The Heightfield Adjust Vertical node can be used to modify the heights of the heighfield it's attached to.


Settings:

  • Set height range: If this is checked the height range of the heightfield will be adjusted so it fits within the "Highest" and "Lowest" values set below. The highest and lowest points of the heightfield are shifted to those values and all other values are scaled to fit inbetween.

  • Highest: Sets the height for the highest points in the heightfield.
    • Highest = off
    Highest = off
    Highest = 500 metres.
    Highest = 500 metres.
    Highest = 3,000 metres.
    Highest = 3,000 metres.


  • Lowest: Sets the height for the lowest points in the heightfield.
    • Lowest = off
    Lowest = off
    Lowest = 500 metres.
    Lowest = 500 metres.
    Lowest = -500 metres.
    Lowest = -500 metres.


  • Multiply height by: If this is checked the heights are multiplied by the specified value. To make a heightfield half as tall you would multiply it by 0.5. To make it twice as tall you would multiply it by 2.
    • Multiply height by 1.
    Multiply height by 1.
    Multiply height by 0.25
    Multiply height by 0.25
    Mulitply height by 3.
    Mulitply height by 3.
    Multiply height by -2.0
    Multiply height by -2.0


  • Add height: If this is checked the all the heights are raised or lowered by the specified value. For example, a value of 200 would shift all heights in the heightfield upward by 200 metres.
    • Add height = 0 metres.
    Add height = 0 metres.
    Add height = 500 metres.
    Add height = 500 metres.
    Add height = -500 metres.
    Add height = -500 metres.


A single object or device in the node network which generates or modifies data and may accept input data or create output data or both, depending on its function. Nodes usually have their own settings which control the data they create or how they modify data passing through them. Nodes are connected together in a network to perform work in a network-based user interface. In Terragen 2 nodes are connected together to describe a scene.

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.
