Multi‐style paper pop‐up designs from 3D models

Abstract

Figure 1: A multi-style paper pop-up constructed from a design layout that is automatically generated from an input 3D model. AbstractPaper pop-ups are interesting three-dimensional books that fascinate people of all ages. The design and construction of these pop-up books however are done manually and require a lot of time and effort. This has led to computer-assisted or automated tools for designing paper pop-ups. This paper proposes an approach for automatically converting a 3D model into a multi-style paper pop-up. Previous automated approaches have only focused on single-style pop-ups, where each is made of a single type of pop-up mechanisms. In our work, we combine multiple styles in a pop-up, which is more representative of actual artist's creations. Our method abstracts a 3D model using suitable primitive shapes that both facilitate the formation of the considered pop-up mechanisms and closely approximate the input model. Each shape is then abstracted using a set of 2D patches that combine to form a valid pop-up. We define geometric conditions that ensure the validity of the combined pop-up structures. In addition, our method also employs an image-based approach for producing the patches to preserve the textures, finer details and important contours of the input model. Finally, our system produces a printable design layout and decides an assembly order for the construction instructions. The feasibility of our results is verified by constructing the actual paper pop-ups from the designs generated by our system.

“…This approach has recently been extended by Ruiz et al . [RLYL14] using a broader class of pop‐up mechanisms.…”

Generating animated paper pop-ups from the motion of articulated characters

“…Several papers [13,14,16,17,19] have proposed automated methods to generate pop-up designs from 3D meshes. These works, however, focus on representing the shape of the 3D mesh through paper pop-up design.…”

“…These geometric constraints for validity have already been studied in previous works [16,17,19]. As such, we will not discuss the validity of the mechanisms we are considering, but focus on the output motion of each mechanism and the combinations thereof.…”

“…15). We determine the dimensions of CBV using the intersection checking formulations by [16,17,19]. It is similar to merging the convex hulls of pop-up mechanism at different fold angles.…”

“…Although these tools significantly aid the design process, they still require considerable skill and effort from the user. There are a few automated approaches to generate pop-up designs from 3D meshes [16,17,19]. In our work, we not only want to produce a good representation of the object's shape, but we aim to duplicate its motion as well.…”
