PDF-SpinIt Optimizing Moment of Inertia for Spinnable Objects Moritz B acher Disney Research

Our method optimizes the inertia tensor of an input model by changing its mass distribution allowing long and stable spins even for complex asymmetric shapes Abstract Spinning tops and yoyos have long fascinated cultures around the world with their. On top of those problems a SIGGRAPH logo shaped hole is carved from her side Abstract Solid shapes in computer graphics are often represented with bound ary descriptions eg triangle meshes but animation physically based simulation and geometry proce The unit vectors 1 2 3 B e e e are fixed in the body and directed along a convenient set of axes pass ing through the mass center G The moments of inertia of the body about t hese axes are defined as 22 xx I y z dm 22 yy I x z dm 22 zz I x Very brie64258y it measures an objects resistance inertia to change in its rotational motion It is analogous to the way mass measure the resistance to changes in the objects linear motion Because it has to do with rotational motion the moment of ine Mitra Tel Aviv University University College London ETH Zurich Figure 1 Metarepresentations of two families of shapes where we show one selected probability distribution from each representation Here we see the distribution for the angle between the ethzch Victor Shoup IBM Zurich Research Laboratory Saumerstr 4 8803 Ruschlikon Switzerland shozurichibmcom May 1998 Abstract A new public key cryptosystem is proposed and analyzed The scheme is quite practical and is provably secure against adaptive How did we get here and where do we go now?.
