Identifying and Visualizing Terrestrial Magnetospheric Topology using Geodesic Level Set Method

  •  27 November 2023

Graphical Abstract

Description unavailable

This study introduces a novel numerical method for identifying and visualizing the terrestrial magnetic field topology in a large-scale 3D global MHD simulation. Our visualization enables us to fill the gaps between current magnetospheric physics and nonlinear dynamics in the future.

Real‐time Terrain Enhancement with Controlled Procedural Patterns

  •  23 November 2023

Graphical Abstract

Description unavailable

Our procedural model enhances a low-resolution input terrain with spatially varying erosion patterns. (a) Input terrain h. (b) Large patterns r(1) generated consistently with the terrain. (c) Narrow patterns r(2) added in cascade, based on the same formulation. (d) A fractional Brownian motion improves the appearance of crest lines.

Curvature‐driven Multi‐stream Network for Feature‐preserving Mesh Denoising

  •  23 November 2023

Graphical Abstract

Description unavailable

A novel multi-stream graph convolutional network for 3D mesh feature-preserving denoising. Gaussian curvature is introduced into the 3D mesh denoising deep network, which improves the feature-preserving denoising performance.

SkyGAN: Realistic Cloud Imagery for Image‐based Lighting

  •  17 November 2023

Graphical Abstract

Description unavailable

SkyGAN generates cloudy sky images from a user-chosen sun position that are readily usable as an environment map in any rendering system. We leverage an existing clear sky model to produce the input to our neural network which enhances the sky with clouds, haze and horizons learned from real photographs.
