Summary
This study introduces an automatic algorithm for designing paper sliceforms, a type of foldable papercraft. The method ensures stable, flat-foldable, and physically realizable designs from 3D models.
Area of Science:
- Computational geometry
- Computer graphics
- Papercraft design
Background:
- Paper sliceforms (lattice-style pop-ups) are foldable structures made from slotted paper patches.
- Automatic design of these structures is computationally challenging and lacks robust methods.
Purpose of the Study:
- To develop novel geometric formulations for valid paper sliceform designs.
- To present an automatic algorithm for generating sliceform designs from 3D models.
Main Methods:
- Geometric formulations considering stability, flat-foldability, and physical realizability.
- Approximating 3D models with generalized cylinders to reduce search space.
- Algorithm generates interlocking-free slots for physical assembly.
Main Results:
- A set of sufficient conditions for valid sliceform construction.
- An automatic algorithm generating valid sliceform designs from 3D models.
- Demonstrated successful creation of real paper sliceforms from generated designs.
Conclusions:
- The proposed method enables automatic generation of stable, flat-foldable, and physically realizable paper sliceforms.
- The approach simplifies the design process for complex papercraft structures.
- The algorithm ensures local pairwise assembility, leading to global assembly.
