# Fractal Interpolation
|
|
|
|
Fill masked regions using fractal interpolation. Matches the spectral characteristics of the surrounding surface to produce natural-looking infill that preserves texture. Better than Laplace for rough surfaces. Equivalent to Gwyddion's fraccor.c module.

## Notes
|
|
|
|
- Fractal interpolation synthesizes fill data whose power spectrum matches the surrounding surface. This produces a more realistic appearance than Laplace interpolation for textured or rough surfaces.
|
|
- The fill region boundaries are smoothed via relaxation to ensure continuity.
|
|
- For very smooth surfaces, Laplace Interpolation may produce cleaner results.
|
|
- The seed for random synthesis is fixed for reproducibility.
