Heightfield Generate - Tweak Fractal Tab

Description:
The Tweak Fractal tab has parameters which let you change some aspects of the fractal used to generate the heightfield.


Settings:

  • Variation: This setting controls the overall variation of the fractal. Variation relates to the distribution of small and large features in the fractal pattern. If Variation is set to 0 then small and large features are evenly distributed. As the value becomes larger the noise starts to vary less evenly, giving a pattern with increasingly uneven distribution between small and large features.
  • Variation method: This popup lets you choose several ways of applying Variation to the fractal. The options available are:

    • Clamped multifractal: TBC
    • Unclamped multifractal: TBC

    • Multi-scale modulator: TBC

  • Buoyancy from variation: This setting adjusts how quickly the variation, as described above, changes.


Back to: Heightfield Generate

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.
