Parameter‐Preserving Real‐time BIM Rendering via Direct GPU Ray Tracing
Computer Animation and Virtual Worlds, Volume 37, Issue 4, July/August 2026.Parametric BIM geometry is preserved from Revit extraction to GPU ray tracing without mesh tessellation. A two‐tier cache reuses repeated geometry during export, and an instanced OptiX representation reduces memory at render time. The method lowers export time and GPU memory while preserving exact curved surfaces.

Computer Animation and Virtual Worlds, Volume 37, Issue 4, July/August 2026.MGGAN learns complex, high‐dimensional patterns and geometric statistics of a single 3D mesh using a multiscale graph‐based generative adversarial network. By combining spectral and spatial graph operators in a coarse‐to‐fine framework with noise injection at each scale, the method generates smooth, visually coherent, and topology‐preserving shape ...

Orthopaedic Surgery, Volume 18, Issue 7, Page 1375-1397, July 2026.This study designed a novel anterolateral screw placement technique and, based on this, developed a new anterolateral fixation method. Imaging, biomechanical, and short‐term efficacy analyses revealed that the Anterolateral Transpedicular Transverse Process Screw (ALTTS) technique achieves a high success rate for L5 vertebral fixation (pedicle width ...

Palaeontology, Volume 69, Issue 4, July/August 2026.Abstract Galeaspids are an extinct group of jawless fishes from the Silurian–Devonian of China and northern Vietnam that are key to understanding the origin of vertebrate anatomical innovations. A new eugaleaspid, Bataspis crux gen. et. sp. nov., is described based on fossil material from the Lochkovian (Early Devonian) Xishancun Formation of Qujing ...

Unstructured grids on NURBS surfaces [PDF]
11th Applied Aerodynamics Conference, 1993 A simple and efficient computational method is presented for unstructured surface grid generation. This method is built upon an advancing front technique combined with grid projection. The projection technique is based on a Newton-Raphson method. This combined approach has been successfully implemented for structured and unstructured grids.
