Morphing of Triangular Meshes in Shape Space [PDF]

open access: yes, 2008
We present a novel approach to morph between two isometric poses of the same non-rigid object given as triangular meshes. We model the morphs as linear interpolations in a suitable shape space $\mathcal{S}$.

Drawing Area-Proportional Euler Diagrams Representing Up To Three Sets [PDF]

open access: yes, 2013
Area-proportional Euler diagrams representing three sets are commonly used to visualize the results of medical experiments, business data, and information from other applications where statistical results are best shown using interlinking curves ...

A new doubly discrete analogue of smoke ring flow and the real time simulation of fluid flow

open access: yes, 2007
Modelling incompressible ideal fluids as a finite collection of vortex filaments is important in physics (super-fluidity, models for the onset of turbulence) as well as for numerical algorithms used in computer graphics for the real time simulation of ...

3D Reconstruction of Geometries for Urban Areas Supported by Computer Vision or Procedural Generations

open access: yesMathematics
This work presents a numerical mesh generation method for 3D urban scenes that could be easily converted into any 3D format, different from most implementations which are limited to specific environments in their applicability.

Geometry‐Based Scan Curve Analysis: Rapid Method for the Evaluation of Scan Strategies in Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents rapid evaluation methods for scan strategies in powder bed fusion (PBF) of polymers with a NIR laser as an example for its application. It uses line buffer‐based calculations and point density fields to predict the performance of four different scan strategies. The methods show promising results in laser‐based PBF of polymer samples,

PS: Polygon Streams A Distributed Architecture for Incremental Computation Applied to Graphics [PDF]

open access: yes, 1991
Polygon Streams is a distributed system with multiple processors and strictly local communication. A unique custom VLSI chip that constitutes an independent processing module forms a stage of the PS pipeline. The number of these modules in PS is a variable that is determined by the application.

L-systems in Geometric Modeling

open access: yes, 2010
We show that parametric context-sensitive L-systems with affine geometry interpretation provide a succinct description of some of the most fundamental algorithms of geometric modeling of curves.

Scaling‐Up of Structural Superlubricity: Challenges and Opportunities

open access: yesAdvanced Functional Materials, EarlyView.
At increasing length‐scales, structural superlubricity (SSL) faces challenges from physical and chemical energy dissipation pathways. This study reviews recent experimental and theoretical progress on these challenges facing the scaling‐up of SSL, as well as perspectives on future directions for realizing and manipulating macroscale superlubricity ...

Optimizing Metamaterial Inverse Design with 3D Conditional Diffusion Model and Data Augmentation

open access: yesAdvanced Materials Technologies, EarlyView.
A generative AI model, the 3D conditional diffusion model (3D‐CDM), is introduced to enhance the inverse design of voxel‐based metamaterials. A data augmentation technique based on topological perturbation expands the dataset, further improving generation quality and accuracy.
