WebThis is a technique for reconstructing a surface mesh from an input point cloud. This approach “learns” from a single object, by optimizing the weights of a CNN to deform some initial mesh to shrink-wrap the input point cloud. A deformable mesh wraps around a point cloud and iteratively learns its internal features to reconstruct a 3d ...
