Abstract: A computing system may include a voxel access engine configured to access voxel data and a voxel processing engine. The voxel processing engine may identify and label thin features in the voxel data, smooth the voxel data to preserve the thin features, and convert the voxel data to form a faceted representation. The voxel processing engine may also adaptively perform a pressing process on the faceted representation. Responsive to a determination that a pressing reapplication criterion is satisfied, the voxel processing engine may modify the voxel data, convert the modified voxel data to form the faceted representation of the object, and perform the pressing process on the faceted representation of the object formed through the modified voxel data.
