spin-it: optimizing moment of inertia for spinnable objects
Bookmarked 605 weeks ago
link to press release and project page: http:wwwdisneyresearchcomprojectspin-itspinning tops and yo-yos have long fascinated cultures around the world with their unexpected graceful motions that seemingly elude gravity we present an algorithm to generate designs for spinning objects by optimizing rotational dynamics properties as input the user provides a solid 3d model and a desired axis of rotation our approach then modifies the mass distribution such that the principal directions of the moment of inertia align with the target rotation frame we augment the model by creating voids inside its volume with interior fill represented by an adaptive multi-resolution voxelization the discrete voxel fill values are optimized using a continuous nonlinear formulation further we optimize for rotational stability by maximizing the dominant principal moment we extend our technique to incorporate deformation and multiple materials for cases where internal voids alone are insufficient our method is well-suited for a variety of 3d printed models ranging from characters to abstract shapes we demonstrate tops and yo-yos that spin surprisingly stably despite their asymmetric appearance
