Abstract
This paper presents a flexible method to reconstruct
simplified mesh surfaces from large unstructured point
sets, extending recent work on dynamic surface recon-
struction. The method consists of two core components:
an efficient selective reconstruction algorithm, based on
geometric convection, that simplifies the input point set
while reconstructing a surface, and a local update al-
gorithm that dynamically refines or coarsens the recon-
structed surface according to specific local sampling
constraints.
A new data structure is introduced that significantly
accelerates the original selective reconstruction algo-
rithm and makes it possible to handle point set models
with millions of sample points. This data structure
mixes a kd-tree with the Delaunay triangulation of
