Heightfield Smooth

Node description and purpose:
The Heightfield Smooth node can smooth a heightfield. Here is an movie showing the effect of the node as the Smooth Radius setting changes from 0 to 1000:


Node Type: Heightfield Operator


  • Smooth Radius: This is the size of the area smoothed by the node. As the value increases the smoother the heightfield will become. 0 performs no smoothing. A setting of 10 will smooth a heighfield point using the 10 nearest points all the way around that point.

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.
