Article Abstract

Considering the dental CBCT images' characteristics, the method of deformable surface of 3D triangle mesh model is proposed. The method uses a deformable model which is initialized from an icosahedron and evolves to fit the teeth's surface by the application of the locally adaptive external forces computed from the image data and internal forces coming from the model itself. The experimental results indicate that the proposed method is robust and accurate.

Headlamp design is an essential aspect of the automotive industry, often relying on reflector systems composed of freeform surfaces. Traditional methods depend on manually adjusting surfaces to ensure reflected rays meet regulation requirements, which is time-consuming and often limited by design features. In this work, we propose a regulation-aware approach to freeform headlamp reflector design using differentiable ray tracing.

This paper presents a new algorithm, Weighted Squared Volume Minimization (WSVM), for generating high-quality tetrahedral meshes from closed triangle meshes. Drawing inspiration from the principle of minimal surfaces that minimize squared surface area, WSVM employs a new energy function integrating weighted squared volumes for tetrahedral elements. When minimized with constant weights, this energy promotes uniform volumes among the tetrahedra.

This paper presents a mesh fault-tolerant repair algorithm tailored to address common geometric issues inherent in electromagnetic models. During the actual production design phase, electromagnetic models frequently display a variety of geometric imperfections due to factors such as design errors and model complexity. These imperfections encompass surface leakage, interpenetrating assemblies, contact, excess material, and minute gaps among multiple components.

Superior lumbar hernias are rare abdominal wall defects that protrude through the superior lumbar triangle and are often misdiagnosed due to their infrequency. This case highlights the successful mesh-free repair of a superior lumbar hernia in a 64-year-old patient, who initially presented with a growing lump and intermittent pain. Though initially suspected to be a sub-fascial lipoma, magnetic resonance imaging was crucial in revealing the true diagnosis.

In recent years, there has been a significant increase in publicly available skeleton descriptions of real brain cells from laboratories all over the world. In theory, this should make it is possible to perform large-scale realistic simulations on brain cells. However, currently there is still a gap between the skeleton descriptions and high-quality simulation-ready surface and volume meshes of brain cells.
