Soma progressive reconstruction. The soma is modeled by a soft body sphere in (a). The initial and final locations of the primary branches are illustrated by the green and red points respectively. The first-order sections are projected to the sphere to find out the vertices where the hooks will be created. The faces from each hook are merged into a single face and shaped into a circle (b). The hooks are pulled and the circles are scaled to match the size of the sections (c-e). The final soma is reconstructed in (f)
