It's all about the Flow...
Flowing, organic forms are what I love in sculpture, productdesign and graphics. Smooth surfaces accentuated by clear edges and wherever possible: reduction and simplicity.
For this I often start with Subdivision Surface Modelling for instance in Rhino or Blender.
In a seconds step - when needed - I convert the polygon mesh to NURBS for the construction of precise technical detail.
On the other hand I enjoy procedural design and organic complexity, where the "simplicity" happens in the mind of the viewer from how the detail flows together. Like in a tree or a wheatfield in the wind.
My software of choice for this is the amazing SideFX Houdini
For prototyping I have two FDM 3D-printers to directly test and feel designs as they evolve.
Up to 35 x 35 x 40cm are possible.
