Abstract:
|
With this thesis, I present a method for creating footprints and tunnels in a surface
through the use of layered geometry. Rather than using a single geometric surface,
deformations are created through the interaction of a polygonal object with multiple
layered planes. Contrary to common methods such as solely using displacement
maps or techniques used in fluid dynamics, none of the layered geometry moves.
With adaptive filtering and layered geometry, one can create complex deformations
resulting from sliding, digging, and surfacing. Its volumetric nature allows interaction
to create overlapping shapes, tunnels, and holes in a surface, while alleviating the
ultimate problem of broken geometry. |
