54
- - **`g7`**: The topological genus of the surface. Here, genus 7 (i.e., the surface has 7 holes).
55
- - **`lissajous` or `fibonacci`**: Parameterization type. Most examples are *Lissajous* (singular) knots; a few are *Fibonacci* knots.
56
- - **`3,5,8`**: Frequencies (`n_x`, `n_y`, `n_z`) used in the parametric equations of the curve, corresponding to the x, y, and z coordinates.
57
- - **`0,pi2,0`**: Phase shifts (`φ_x`, `φ_y`, `φ_z`) in each coordinate. Notation like `pi2` represents multiples of π (e.g., `pi2` = π/2, `pi3` = π/3, etc.).
58
- - **`03_1.1_0.2`**: Parameters of the cosine-based radius modulation for the tubular neighborhood around the curve:
59
  - `03`: frequency `f`
60
  - `1.1`: constant term `c`
61
  - `0.2`: amplitude `a`

- - **`r0.02_0.029`**: Minimum and maximum radius values of the tubular neighborhood.

- - **`v90`**: Voxel resolution per axis. While v90 nominally refers to a 90 × 90 × 90 voxel grid, an offset of at least 5 voxels per side (sometimes 10 or 15) was added to prevent surface clipping at the bounding box edges. As a result, the actual scalar field is discretized into 101 × 101 × 101 grid points (vertices), yielding 1,000,000 voxels in total. This expanded grid ensures sufficient padding around the surface geometry.

  Other file variants use suffixes to indicate their content:

75
- - **`_sf.txt`**: The scalar field used to generate the surface.
