  text: 'We present a computational approach for unfolding 3D shapes isometrically
    into the plane as a single patch without overlapping triangles. This is a hard,
    sometimes impossible, problem, which existing methods are forced to soften by
    allowing for map distortions or multiple patches. Instead, we propose a geometric
    relaxation of the problem: We modify the input shape until it admits an overlap‐free
    unfolding. We achieve this by locally displacing vertices and collapsing edges,
    guided by the unfolding process. We validate our algorithm quantitatively and
    qualitatively on a large dataset of complex shapes and show its proficiency by
    fabricating real shapes from paper.'
