| dc.description.abstract | The detailed 3D environment becomes an essential way
for offering the richest user experience in the digital entertainment
or virtual reality application. Model synthesis
[Mer07,MM08,MM09,MM11] is one of the effective methods
to create 3D complex shapes from an example. Compared
with other methods, this method can realize multidirectional
extending easily. Besides, it is a general-purpose
modeling tool, which can accept many different example
models. One problem of prior work in model synthesis is
that it can only extend example models on the regular grid
structure. It is inefficient when people need to create some
non-parallel or curved structures, which are more popular in
the real world. To solve it, we extend the previous adjacent
constraint by relaxing the boundary matching constraint,
and the constraint is called generalized adjacent constraint.
Through a boundary consistency analysis, more adjacent
relation can be found to support synthesis on the irregular
structure. Then an optimization framework is introduced to
refine the synthesis result by maximizing an energy function. | en_US |
