3D Reconstruction From Non-Euclidian Distance Fields
Anders Sandholm, Ken Museth · 2004
Figure 1: Left: Naive reconstruction by linear interpolation of 2D Euclidian distances to aliased (i.e. binary) input contours of a two-headed dragon. Note the semi-transparent image plane corresponding to one of the horizontal sampling planes. Middle: Our improved spline interpolation of Non-Euclidian distances. Right: Hight-field representations of the two distance fields shown as semi-transparent planes. Green is the Euclidian distance and red is the non-Euclidian distance. Note how the smoothing suppresses the medial-axis on the red surface.
