Reconstruction of surfaces with ordinary singularities from their silhouettes

Published 12 Oct 2018 in math.AG and cs.SC | (1810.05559v2)

Abstract: We present algorithms for reconstructing, up to unavoidable projective automorphisms, surfaces with ordinary singularities in three dimensional space starting from their silhouette, or "apparent contour" - namely the branching locus of a projection on the plane - and the projection of their singular locus.
