As-Rigid-As-Possible Surface Modeling - Olga Sorkine-Hornung
face deformations induced by modeling operations are close to rigid, surface details tend to be preserved. This is a highly important property for surface editing schemes that are meant to be applied to complex, detailed surfaces, such as those coming from scanning real 3D objects or from sophis-ticated virtual sculpting tools.

Least-Squares Rigid Motion Using SVD
igl.ethz.chremind the reader that the trace of a square matrix is the sum of the elements on the diagonal: tr(A) = P n i=1 a ii. See Figure 1 for an illustration of the algebraic manipulation. Therefore we are looking for a rotation Rthat maximizes tr WYTRX. Matrix trace has the property tr(AB) = tr(BA) (15) for any matrices A;Bof compatible dimensions ...

Learning Implicit Fields for Generative Shape Modeling
openaccess.thecvf.comWith remarkable progress made on generative modeling of images using VAEs [24], GANs [3, 15, 34], autoregres-sive networks [41], and flow-based models [23], there have been considerably fewer works on generative models of 3D shapes. Girdhar et al. [14] learned an embedding space of 3D voxel shapes for 3D shape inference from images and shape ...
