With 3D structural modeling from selected bead–bead interactions, there must be a balance of the ratio of constraints to the total number of possible pairwise interactions.

A new urban 3D reconstruction method enhances Tomographic Synthetic Aperture Radar (TomoSAR) imaging using geometric semantics.

But, with the rise of hobbyist 3D printing, a number of much more simple CAD programs became available. While these programs certainly helped makers get into 3D modeling, most had serious limitations.
