Differentiable Geodesic Distance for Intrinsic Minimization on Triangle Meshes
https://doi.org/10.1145/3658122
[ "Yue Li", "Logan Numerow", "Bernhard Thomaszewski", "Stelian Coros" ]
Computing intrinsic distances on discrete surfaces is at the heart of many minimization problems in geometry processing and beyond. Solving these problems is extremely challenging as it demands the computation of on-surface distances along with their derivatives. We present a novel approach for intrinsic minimization o...

Gaussian Splatting has emerged as a prominent model for constructing 3D representations from images across diverse domains. However, the efficiency of the 3D Gaussian Splatting rendering pipeline relies on several simplifications. Notably, reducing Gaussian to 2D splats with a single viewspace depth introduces popping ...

[ "Junwei Zhou", "Duowen Chen", "Molin Deng", "Yitong Deng", "Yuchen Sun", "Sinan Wang", "Shiying Xiong", "Bo Zhu" ]
We propose a novel Particle Flow Map (PFM) method to enable accurate long-range advection for incompressible fluid simulation. The foundation of our method is the observation that a particle trajectory generated in a forward simulation naturally embodies a perfect flow map. Centered on this concept, we have developed a...

Ray Tracing Harmonic Functions
https://doi.org/10.1145/3658201
[ "Mark Gillespie", "Denise Yang", "Mario Botsch", "Keenan Crane" ]
Sphere tracing is a fast and high-quality method for visualizing surfaces encoded by signed distance functions (SDFs). We introduce a similar method for a completely different class of surfaces encoded by harmonic functions , opening up rich new possibilities for visual computing. Our starting point is similar in spiri...

An Induce-on-Boundary Magnetostatic Solver for Grid-Based Ferrofluids
https://doi.org/10.1145/3658124
[ "Xingyu Ni", "Ruicheng Wang", "Bin Wang", "Baoquan Chen" ]
This paper introduces a novel Induce-on-Boundary (IoB) solver designed to address the magnetostatic governing equations of ferrofluids. The IoB solver is based on a single-layer potential and utilizes only the surface point cloud of the object, offering a lightweight, fast, and accurate solution for calculating magneti...

The real world exhibits rich structure and detail across many scales of observation. It is difficult, however, to capture and represent a broad spectrum of scales using ordinary images. We devise a novel paradigm for learning a representation that captures an orders-of-magnitude variety of scales from an unstructured c...

From microfacets to participating media: A unified theory of light transport with stochastic geometry
https://doi.org/10.1145/3658121
[ "Dario Seyb", "Eugene d'Eon", "Benedikt Bitterli", "Wojciech Jarosz" ]
Stochastic geometry models have enjoyed immense success in graphics for modeling interactions of light with complex phenomena such as participating media, rough surfaces, fibers, and more. Although each of these models operates on the same principle of replacing intricate geometry by a random process and deriving the a...

[ "Jingyu Zhuang", "Di Kang", "Yan-Pei Cao", "Guanbin Li", "Liang Lin", "Ying Shan" ]
Text-driven 3D scene editing has gained significant attention owing to its convenience and user-friendliness. However, existing methods still lack accurate control of the specified appearance and location of the editing result due to the inherent limitations of the text description. To this end, we propose a 3D scene e...

Cyclones are large-scale phenomena that result from complex heat and water transfer processes in the atmosphere, as well as from the interaction of multiple hydrometeors , i.e., water and ice particles. When cyclones make landfall, they are considered natural disasters and spawn dread and awe alike. We propose a physic...
