Differentiable Randers‐Finsler Eikonal Solvers

Computer Graphics Forum, EarlyView.
Abstract Fast and differentiable solvers for anisotropic and asymmetric distance fields are a key primitive in geometry processing, enabling gradient‐based optimization over metrics, drift fields, and downstream objectives that depend on geodesic distances and geodesics.

Individualized Pathfinding in Rugged Open Terrains Using Semantic Navigation Meshes

Computer Graphics Forum, EarlyView.
We introduce semantic navigation meshes for complex outdoor terrains, partitioning space into regions with coherent semantic properties like slope or vegetation density. The resulting graphs enable efficient pathfinding with agent‐specific, parameterized cost functions without precomputation, accelerating search while maintaining path quality close to ...

Phong‐Rodrigues Extrinsic Vector‐Field Processing

Computer Graphics Forum, EarlyView.
Abstract We introduce a new extrinsic discretization of tangent vector fields on triangle meshes that is continuous, with bounded derivatives that are continuous almost everywhere, supporting pointwise evaluation and integration of differential operators.

On Bending in the As‐Rigid‐As‐Possible Deformation Energy

Computer Graphics Forum, EarlyView.
Abstract The well‐established As‐Rigid‐As‐Possible (ARAP) energy has various forms. For surface deformation, commonly used energies contain an implicit bending penalty. We present a natural, continuous generalization that incorporates multiple ARAP versions with an implicit, user‐controllable bending penalty.

Geodesics in Goedel-Synge spaces

, 1982
Our purpose is to study the geodesic lines in the form: ds2=dx2 + 2h(x4)dx1dx2 + g(x4)dx22 – dx23 – dx24, and to compare with the work of S. Chandrasekhar and J. P. Wright on geodesics in Gödel’s universe. We will give, first, an isometric embedding of the form ds2=dx2 + 2h(x4)dx1dx2 + g(x4)dx22 – dx23 – dx24 in a pseudo Euclidean space of 10 ...

Arti4D: Statistical Analysis and Modelling of the Spatio‐temporal Variability in Articulated 4D Shapes

Computer Graphics Forum, EarlyView.
Abstract We propose a novel framework for the statistical modeling and analysis of the spatio‐temporal shape variability in articulated 4D (i.e., 3D + time) shapes such as human bodies and animals. We treat articulated 3D shapes, represented using parametric models such as SMPL or its variants, as elements of the product space of shape and pose ...
