Here you can download two very interesting 3D models of organic chairs, each in several variants, whereby one model is named ‘Isocurves Chair’ and the other ‘Voronoi Chair’.

The initial step for both chairs is the same - modeling the chair surface. The Isocurves organic chair was obtained by manipulating isoparametric curves, i.e., with the UV grid of this surface, and the Voronoi chair was obtained after applying the Voronoi pattern to the chair surface. As you can see, the result is extremely interesting. These chairs were designed to be as close in appearance and dimensions as possible to real chairs, but you are not advised to try to make them yourself. We know that only few of you have a 3D printer of the right size or is capable of manufacturing such a large mold; therefore, it is important to note that these chairs haven’t been designed to be made but rather to be used as 3D models.

UV and Voronoi organic chair
3D CAD software used for modeling

Rhino 3D + Grasshopper plug-in

Available NURBS and BREP file formats

STEP (Standardized 3D graphic exchange file format) and 3DM (Rhinoceros 3D native file format)

Available polygonal mesh file formats

OBJ (Wavefront)


There are several versions for each type of chair. With the Isocurves organic chair, we changed the density of UV lines, which resulted in a larger number of smaller holes and vice versa. With the Voronoi chair, we varied the appearance of the Voronoi cells and their dimensions, i.e., their number on the surface. The problem arises when you want to produce them; this is simply not possible at home and becomes too complex in industrial conditions. The 3D model can be used for creating and rendering some interesting interior, you can make your own 3D solid or surface model from a 3D mesh that is also available to you, import it into some other 3D CAD software and exercise or try different things on it. Instead of chairs, you can apply this organic look to various other objects such as vases, panels, facades, table legs… there are many possibilities.
