abstract = "A complete solution for creating an entire planet by combining
different types of elements from an intuitive specification is
still an open problem. High-level techniques are at the core of
the solution for this issue. In this context, our work aims to
contribute for the development of high-level techniques for
landscape creation by the proposal of two approaches. The first
deals with the manipulation of the position of landscape elements
(according to some criteria), and the second is related to the
generation of terrains from two new data-driven methods. In
particular, we introduced a flexible method for resizing a
landscape specification keeping the overall appearance. It is
based on the insertion and removal of objects followed by scene
adjustment (enlargement or shrinking). Furthermore, we introduced
two data-driven techniques for terrain synthesis. They are
developed over the same intuitive control approach, and they take
advantage of the geometric nature of the data for improving the
synthesis. The first technique is a patch-based algorithm, with
new optimization structures for patch choice, and a new patch
insertion approach (both based on the geometric nature of the
data). The second is a pixel-based method, based on a graph of
exemplars in multiresolution.",
