Description: Poisson surface reconstruction creates watertight surfaces from oriented
point sets. In this work we extend the technique to explicitly incorporate
the points as interpolation constraints. The extension can be interpreted as
a generalization of the underlying mathematical framework to a screened
Poisson equation. In contrast to other image and geometry processing
techniques, the screening term is defined over a sparse set of points rather
than over the full domain. We show that these sparse constraints can
nonetheless be integrated efficiently. Because the modified linear system
retains the same finite-element discretization, the sparsity structure is
unchanged, and the system can still be solved using a multigrid approach.
Moreover we present several algorithmic improvements that together
reduce the time complexity of the solver to linear in the number of points,
thereby enabling faster, higher-quality surface reconstructions. Platform: |
