A Novel Multidisciplinary Approach for Reptile Movement and Behavior Analysis

Integrative Zoology, EarlyView.
We present a novel multidisciplinary approach capable of advancing research on reptiles’ behavior. Our approach uses integrated tools and methods for the digitization, reconstruction, and visualization of reptiles and their behavior. We (i) record movement through tri‐axial accelerometers, video cameras, and motion capture systems; (ii) ground‐truth ...

Neural Geometry Processing via Spherical Neural Surfaces

Computer Graphics Forum, EarlyView.
Abstract Neural surfaces (e.g., neural map encoding, deep implicit, and neural radiance fields) have recently gained popularity because of their generic structure (e.g., multi‐layer perceptron) and easy integration with modern learning‐based setups. Traditionally, we have a rich toolbox of geometry processing algorithms designed for polygonal meshes to

Isosurface Extraction for Signed Distance Functions using Power Diagrams

Computer Graphics Forum, EarlyView.
Abstract Contouring an implicit function typically considers function values in the vicinity of the desired level set, only. In a recent string of works, Sellán at al. have demonstrated that signed distance values contain useful information also if they are further away from the surface.

geometric modeling based on polygonal meshes

, 2000
In the last years triangle meshes have become increasingly popular and are nowadays intensively used in many different areas of computer graphics and geometry processing. In classical CAGD irregular triangle meshes developed into a valuable alternative to traditional spline surfaces, since their conceptual simplicity allows for more flexible and highly

S‐ACORD: Spectral Analysis of COral Reef Deformation

Computer Graphics Forum, EarlyView.
Abstract We propose an efficient pipeline to register, detect, and analyze changes in 3D models of coral reefs captured over time. Corals have complex structures with intricate geometric features at multiple scales. 3D reconstructions of corals (e.g., using Photogrammetry) are represented by dense triangle meshes with millions of vertices.

Inverse Simulation of Radiative Thermal Transport

Computer Graphics Forum, EarlyView.
Abstract The early phase of urban planning and architectural design has a great impact on the thermal loads and characteristics of constructed buildings. It is, therefore, important to efficiently simulate thermal effects early on and rectify possible problems.

Lipschitz Pruning: Hierarchical Simplification of Primitive‐Based SDFs

Computer Graphics Forum, EarlyView.
Abstract Rendering tree‐based analytical Signed Distance Fields (SDFs) through sphere tracing often requires to evaluate many primitives per tracing step, for many steps per pixel of the end image. This cost quickly becomes prohibitive as the number of primitives that constitute the SDF grows.

Learning Metric Fields for Fast Low‐Distortion Mesh Parameterizations

Computer Graphics Forum, EarlyView.
Abstract We present a fast and robust method for computing an injective parameterization with low isometric distortion for disk‐like triangular meshes. Harmonic function‐based methods, with their rich mathematical foundation, are widely used. Harmonic maps are particularly valuable for ensuring injectivity under certain boundary conditions. In addition,
