 # Dataset Description
 
-This dataset contains 3D objects representing a topologically diverse collection of surfaces, each generated from closed, parameterized curves with varying number of self-intersections (singular knots). The surfaces are organized by topological genus, ranging from 0 to 10, so each genus has its own subdirectory. Each surface comprises four files:
+This dataset contains 3D objects representing a topologically diverse collection of surfaces, each generated from closed, parameterized curves with varying number of self-intersections (singular knots). 
+The surfaces are organized by topological genus, ranging from 0 to 10. 
+For each surface, we included the following four files:
 
   - __Non-Smoothed STL Mesh__ (`*_ns.stl`): A 3D mesh of the surface with sharp geometry and unmodified vertex positions. This version retains the raw output of the Marching Cubes algorithm.
     
-  - __Smoothed STL Mesh__ (`.stl`): A geometrically smoothed version of the `*_ns.stl` surface, generated using Laplacian vertex smoothing in Blender.
-
-  - This process adjusts vertex positions to reduce sharp edges and improve regularity, modifying surface area and volume while preserving the mesh connectivity and topological features (e.g., genus and Euler characteristic).

 - `g7`: Topological genus of the surface. In this example, the genus is 7 (i.e., the surface has 7 holes).
-- `lissajous` or `fibonacci`: Knot type. Most elements were generated from *Lissajous* (singular) knots, but just a couple from *Fibonacci* knots.

 - `0,pi2,0`: The phase shifts `φ_x`, `φ_y`, `φ_z` in each coordinate. Notation like `pi2` represents fractions of π (e.g., `pi2` = π/2, `pi3` = π/3, etc.).
