Abstract:
Creating surfaces with intricate small-scale features (microgeometry)
and detail is an important task in geometric
modeling and computer graphics. We present a model
processing method capable of producing a wide variety of
complex surface features based on displacement mapping
and stochastic geometry. The latter is a branch of mathematics
that analyzes and characterizes the statistical properties
of spatial structures. The technique has been incorporated
into an interactive modeling environment that supports
the design of stochastic microgeometries. Additionally
a tool has been developed that provides random exploration
of the technique's entire parameter space by generating
sample microgeometry over a broad range of values.
We demonstrate the effectiveness of our technique by creating
diverse, complex surface structures for a variety of geometric
models, e.g. arrowheads, candy bars, busts, planets
and coral.
