Texture-Lobes for Tree-Modelling
Abstract
We present a lobe-based tree representation for modeling
trees. The new representation is based on the observation that the
tree's foliage details can be abstracted into canonical geometry
structures, termed lobe-textures. We introduce techniques to (i)
approximate the geometry of given tree data and encode it into
a lobe-based representation, (ii) decode the representation and
synthesize a fully detailed tree model that visually resembles the
input. The encoded tree serves as a light intermediate
representation, which facilitates efficient storage and transmission
of massive amount of trees, e.g., from a server to clients for
interactive applications in urban environments. The method is
evaluated by both reconstructing laser scanned trees (given as point
sets) as well as re-representing existing tree models (given as
polygons).
