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 ...

Lithium-Ion Battery Capacity Estimation: A Method Based on Visual Cognition
Complexity, 2017 This study introduces visual cognition into Lithium-ion battery capacity estimation. The proposed method consists of four steps. First, the acquired charging current or discharge voltage data in each cycle are arranged to form a two-dimensional image ...

Controllable Intrinsic Surface Pattern Generation Using Slime Mold Simulations
Computer Graphics Forum, EarlyView.Abstract Surface‐based pattern simulations have proven valuable for texture design and scientific visualization, but existing methods face several limitations. Most simulations either target a narrow range of pattern types (e.g. spots, branching) or support a broad range of patterns at the cost of time‐consuming parameter tuning.

Affine connections for 2-osculating vector fields and geodesics
, 1989 Starting with the work of \textit{A. M. Pastore} [ Rend. Accad. Naz. Sci. Detta XL, IV. Ser. 22-23, 135-148 (1972; Zbl 0414.53008); Rend. Mat. Appl., VII. Ser. 1, 177-190 (1981; Zbl 0477.53018)]\ the authors study the relationship between the geodesics with respect to a connection for 2-osculating vector fields and the curves which are projections of ...

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.

Survey on differential estimators for 3d point clouds
Computer Graphics Forum, EarlyView.Abstract Recent advancements in 3D scanning technologies, including LiDAR and photogrammetry, have enabled the precise digital replication of real‐world objects. These methods are widely used in fields such as GIS, robotics, and cultural heritage. However, the point clouds generated by such scans are often noisy and unstructured, posing challenges for ...

Vector fields, flows and geodesics on supermanifolds
Champs de vecteurs, flots et géodésiques sur les supervariétés Le résultat principal de cette thèse est de donner une définition de géodésique sur les supervariétés riemanniennes (\ca,g) paires (et aussi impaires) et de la justifier par un théorème reliant les courbes géodésiques avec le flot géodésique sur \text{T}^*\ca. Pour ce faire,
