The 3D model presents a historical mannequin (a dress form) dating to 1900s. The virtual mannequin was generated automatically by using a new method of parametric modelling (for further details see https://doi.org/10.1108/IJCST-06-2019-0093). The values of body measurements were taken from a sizing table. The measurements are: bust – 81.4 cm; waist – 51.4 cm; hip – 92.4 cm. A video presentation of the 3D model is available at https://youtube.com/playlist?list=PLCTQCzEpoeLvTramFMrmp93PEDaIVTLKR&feature=shared

A parametric study of a continuous loop characterized by a modulating cross-section.

I built fully parametric branches using Blender Geometry Nodes.
The hierarchy between branches is determined by their positions in the texture maps, so the positioning parameters in the Geometry Node setup will differ for different textures. Achieving consistent shapes across different LODs is particularly difficult, yet quite challenging. Later, I will use this same method to create various trees from these branches and build my own plant library.

This object is a computational reconstruction of the classical Klein bottle, a non-orientable surface where inside and outside become indistinguishable.

The model is built from a high-resolution parametric domain (256 × 128), generating 32,768 vertices and over 230k total edges, including 166k structural edges.
Multiple edge families — bands, braids, bridges, and seam connections — reveal the internal organization of the surface and make the topology visually readable.

A spectral encoding system maps intrinsic geometric channels (seam proximity, twist, braid energy, and latitude phase) into vertex color and scale, transforming the surface into an informational object rather than a purely aesthetic form.

Because a true Klein bottle cannot embed in 3D space without intersection, the object is shown as an immersed surface in ℝ³, where self-contacts naturally emerge from the topology itself.
