The printing time and cost significantly for stop-motion animated films. Parameters and compare our results to naive solutions. Results on a variety of facial animations, both digital and 3D printed,Ĭritiqued by a professional animator we show the impact of various algorithmic Graph-cut technique to find a set of replacements, whose size can be userĭefined, or automatically computed to adhere to a printing budget or allowedĭeviation from the original animation. Each part is then independently optimized using a The part boundaries are designed to ease 3D printing and
Replacement sets for each part can be interchangeably and seamlessly assembled We then present a novelĪlgorithm to zero out deformations along the segment boundaries, so that Minimal deformation along which to segment the mesh. Parts of the model are preferred for segmentation then, we find curves with Inspired by current stop-motion workflows, a user manually indicates which The input animation, while minimizing the amount of 3D printing and assembly. Per-animation-frame assignment of the parts, such that we maximally approximate Given an input animation sequence of topology invariantĭeforming meshes, our problem is to output a library of replacement parts and Present the first system for processing computer animation sequences (typicallyįaces) to produce an optimal set of replacement parts for use in 3D printed Stop-motion can only be viable if animations can be faithfully reproduced usingĪ compact library of 3D printed and efficiently assemblable parts. Of a computer animation is prohibitively slow and expensive, 3D printed Positively impact traditional stop-motion animation. Computer animation in conjunction with 3D printing has the potential to
