Abstract: One embodiment of the invention is a pop-up engine that generates a pop-up card from a sliced 3D graphics model. In operation, the pop-up engine processes a sliced 3D model to identify locations where the sliced 3D model is to attach to a plane surface of a pop-up card. For a given set of slices associated with a sliced 3D model, the pop-up engine identifies at least two slices that intersect at a folding line of the plane surface. The pop-up engine then identifies locations on the slices that are the farthest from the folding line. The pop-up engine marks the identified locations as connection points, where the 3D model is to attach to the plane surface.

Abstract: One embodiment of the invention is a pop-up engine that generates a pop-up card from a sliced 3D graphics model. In operation, a pop-up engine processes a sliced 3D model to identify locations where each slice of the 3D model is to attach to the pop-up card or to other slices of the 3D model. The pop-up engine traverses the boundary of each slice and, at intervals along the boundary, projects a ray toward the upper portion of the card. If the ray intersects a neighboring slice, then the slice attaches to the neighboring slice at that location. If, however, the ray does not intersect a neighboring slice, then the slice attaches to the upper portion of the card at that location. The pop-up engine then modifies the slice to include a hinge portion that connects the slice to either a neighboring slice or the upper portion at that location.

Abstract: One embodiment of the invention is a slicing engine that generates two or more slices of a virtual 3D model given a slice plane. The slicing engine then determines connection points on each of the slices that indicate how the 3D model is to be reconnected by the user when the 3D model is fabricated. The slicing engine also determines an optimized layout for the various slices of the 3D model on fabrication material for minimal use of the material. The user is then able to “print” the layout on the fabrication material via 3D printers, and connect the various printed slices according to the connection points to build a physical representation of the 3D model.
