Scene 2
“Untitled” by Ai Weiwei

The Original Artwork as Inspiration

Inspired by Ai Weiwei’s “Untitled”, a series of artwork featuring wooden structures.
These wooden structures use the same crafting technique, “joint-structure”, as the wooden chairs used in Scene 2. However, the symmetrical shape and geometric rules applied to the artwork is the essence of its beauty. 
Giving close-up observation of those joints, textures and surface, I have came up with an idea of the wooden sphere forming itself out of nothing, and then growing up into a giant version of the original artwork. At the same time, the geometric shape and dimension will change, thus gives the artwork another appearance and new meanings. To reflects the original artwork, the fundamental rule of the geometrical shape and the material will not be altered.
(These reference video and photography were taken on September, 2014 at Brooklyn Museum of Art.)

Concept Art for the New Artwork

Some concept art was developed at early stage of planning. The idea is to show the progress of how the polyhedron evolve and develop into a larger sculpture.
Sketches were drawn to look for possible variations and compositions. Preliminary 3-D modeling was made in Houdini using procedural modeling method to create the polyhedron and its alterations. 
The image above is the concept sketches of the new artwork, and a pre-viz using 3-D software for testing the growing process.

Procedural modeling gives us the opportunity to create and adjusting 3-D models using mathematical expression. In this case of the original wooden sculpture by the artist, the mathematic rules behind the work is preserved in the CG version of it, but was escalated to another level of complexity.
As for animation, the idea that the artwork is evolving and transforming can be realized through procedural animation, which is based on point information related to the 3-D model and key-framed using parameters and values. By using a combination of transform, rotate and scale, accompanied by copy and stamping objects onto points, the 3-D model now can be manipulated into an endless of possibilities.
