Fractal resampling device?

Is the new fractal resampling device/macro for importing DEMs already in the dev branch? I can’t find it somehow.

Thanks!

Hi there,

Yep. It integrates so easily that its’ easy to miss it :slight_smile:

To use fractal resampling for DEMs, do the following:

  1. Create a file input device, and set the file.
  2. In the “Resampling Method” box below the file details, change from World Default to Fractal. Use the surface roughness parameter to determine how much additional detail to introduce.

Cheers

Ahh, there it is :slight_smile: Thanks!

Quick follow-up: Does the fractal sampling apply a blur filter first? If yes, can the strength be adjusted?

There is no blur applied for the built-in fractal resampling – for most inputs it is not necessary as the underlying smooth interpolation prevents artifacts. In certain cases (such as 8bit input terrains that have badly terraced shapes) you will probably get best results with the oldschool import->blur->add detail technique.
