SDFs from Unoriented Point Clouds using Neural Variational Heat Distances
Computer Graphics Forum, EarlyView.We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from unoriented point clouds. We first compute a small time step of heat flow (middle) and then use its gradient directions to solve for a neural SDF (right). Abstract We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from ...

Potential scattering in the eikonal approximation. II
, 1975 A systematic study is made of several properties of the eikonal approximation and related methods. We first discuss various corrections to the eikonal approximation, in particular the eikonal-Born series method and the eikonal expansion of Wallace.

Massive double copy in the high-energy limit
Journal of High Energy Physics, 2022 The exploration of the massive double copy is still in its infancy, and only a few examples in limited contexts are known. In this paper, we analyze the newly discovered double copy for topologically massive theories beyond tree-level amplitudes in the ...

Wave Tracing: Generalizing The Path Integral To Wave Optics
Computer Graphics Forum, EarlyView.Abstract Modeling the wave nature of light and the propagation and diffraction of electromagnetic fields is crucial for the accurate simulation of many phenomena, yet wave simulations are significantly more computationally complex than classical ray‐based models.

Mesh Processing Non‐Meshes via Neural Displacement Fields
Computer Graphics Forum, EarlyView.Abstract Mesh processing pipelines are mature, but adapting them to newer non‐mesh surface representations—which enable fast rendering with compact file size—requires costly meshing or transmitting bulky meshes, negating their core benefits for streaming applications.

Next-to-next-to-eikonal corrections in the CGC [PDF]
, 2016 We extend the study of corrections to the eikonal approximation that was initiated in Ref. \citeAltinoluk:2014oxa to higher orders. These corrections associated with the finite width of the target are investigated and the gluon propagator in background ...

Power corrections in eikonal cross sections [PDF]
, 2000 We discuss power corrections associated with the infrared behavior of the perturbative running coupling in the eikonal approximation to Drell-Yan and other annihilation cross sections in hadron-hadron scattering.

European Physical Journal C: Particles and Fields, 2022 Elastic diffractive scattering of nucleons is described in terms of Regge-eikonal approach. It is demonstrated that, in a wide kinematic region (starting from the U-70 energies), the eikonal of proton–proton scattering can be approximated by the sum of ...

Contouring Signed Distance Fields by Approximating Gradients
Computer Graphics Forum, EarlyView.Abstract Signed distance fields are often represented by discrete samples (e.g., on a grid). Recovering the contour implicitly represented by the distance samples requires an approximation algorithm. Several recent approaches have shown that exploiting the information carried in each distance sample by explicitly constructing a surface point gives ...
