Spectral processing of point-sampled geometry

  title={Spectral processing of point-sampled geometry},
  author={Mark Pauly and Markus H. Gross},
We present a new framework for processing point-sampled objects using spectral methods. By establishing a concept of local frequencies on geometry, we introduce a versatile spectral representation that provides a rich repository of signal processing algorithms. Based on an adaptive tesselation of the model surface into regularly resampled displacement fields, our method computes a set of windowed Fourier transforms creating a spectral decomposition of the model. Direct analysis and manipulation… CONTINUE READING
