TreeON: Reconstructing 3D Tree Point Clouds from Orthophotos and Heightmaps

open access: yesComputer Graphics Forum, EarlyView.
Abstract We present TreeON, a novel neural‐based framework for reconstructing detailed 3D tree point clouds from sparse top‐down geodata, using only a single orthophoto and its corresponding Digital Surface Model (DSM). Our method introduces a new training supervision strategy that combines both geometric supervision and a differentiable shadow and ...

Survey on differential estimators for 3d point clouds

open access: yesComputer 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 ...

Atmospheric correction of multiple flightline hyperspectral data (CASI-3)

open access: yes, 2008
Multiple parallel airborne flightlines are often necessary to provide the areal coverage desired, but standardisation to a common unit such as reflectance can be difficult, particularly where errors in the transform may be propagated sequentially through

CuRast: Cuda‐Based Software Rasterization for Billions of Triangles

open access: yesComputer Graphics Forum, EarlyView.
Abstract This paper presents a CUDA‐based software rasterizer capable of rendering up to a billion unique triangles, or up to 4 billion instanced triangles, in real time at 60 fps on an RTX 5090. By specifically targeting dense, opaque meshes, our approach is able to outperform the native GPU rasterization pipeline in these scenarios.

Recent Trends in Inverse Rendering

open access: yesComputer Graphics Forum, EarlyView.
This survey reviews 84 papers published between 2020 and 2025 on inverse rendering methods, introducing a taxonomy based on input data, scene representations, optimization strategies, and evaluation methods. We analyze emerging trends in neural, differentiable, and Gaussian‐splatting approaches, discuss applications, and identify key challenges and ...

Segmented Intraoral Scanning With a Palatal Marker for Complete‐Arch Digital Implant Impressions: An In Vitro Comparative Study

open access: yesClinical Oral Implants Research, EarlyView.
ABSTRACT Objectives To compare four complete‐arch implant impression workflows—segmented right/left IOS merged via a palatal marker (IOS‐LEGO‐Seg), continuous full‐arch IOS with a palatal marker (IOS‐LEGO‐Full), continuous full‐arch IOS without a palatal marker (IOS‐Full), and a conventional open‐tray PVS impression followed by cast fabrication and ...

Advancing conservation breeding programs for marine invertebrates

open access: yesConservation Biology, EarlyView.
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

open access: yesJournal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

The impact of alignment and scaling on biological inferences from landmark‐free morphometrics

open access: yesJournal of Anatomy, EarlyView.
Landmark‐free morphometrics promises advancements in shape quantification for biology, but widespread adoption is hampered by concerns over reproducibility. We compare 3D mesh alignment and scaling protocols on a prominent landmark‐free approach, Deterministic Atlas Analysis, finding inconsistencies in centroid size distribution and variance structure.
