A dynamic skin slab, remixed 2008

Keith Waters

Abstract

The construction of a three-dimensional skin slab with linear muscle contraction. Orginally developed on using Iris GL this version runs on a MAC using OpenGL. It is highly interactive, allowing the muscles to be positioned and contracted.

Figure 1. The three-dimensional muscle volume lattice with a textured skin surface.

Each unit is based on a hexahedral element that represent the epidermis, which in turn is attached to the subsurface.

The muscle fibers themselves contribute to the dynamic system.

Notice that the increacing defomration causes buckling and creasing of the surface as the elements preserve their volume strucutre.
