标题： Real-Time Cloth Simulation Using WebGPU: Evaluating Limits of High-Resolution

摘要： 本研究探讨了WebGPU这一新兴的网络图形范式在实时布料模拟中的能力。 传统的基于WebGL的方法由于侧重于图形渲染而非通用GPU（GPGPU）操作，因此在处理复杂的物理模拟时存在局限。 WebGPU旨在提供现代3D图形和计算能力，通过并行处理和对计算着色器的支持实现了显著的改进。 在这项工作中，我们使用WebGPU框架中的质点-弹簧方法实现了一个布料模拟系统，将碰撞检测和响应处理与3D表面模型集成。 首先，比较性能评估表明，WebGPU在高分辨率模拟中明显优于WebGL，在最多640K节点的情况下仍能保持每秒60帧（fps）。 第二个实验旨在确定WebGPU的实时限制，并确认WebGPU可以实时处理4K至100K布料节点模型与100K三角形表面模型之间的碰撞。 这些实验还强调了在处理布料模型与复杂3D物体之间的碰撞时，平衡实时性能与真实渲染的重要性。 我们的源代码可在https://github.com/nakjun/Cloth-Simulation-WebGPU获取 显示英文摘要

摘要： This study explores the capabilities of WebGPU, an emerging web graphics paradigm, for real-time cloth simulation. Traditional WebGL-based methods have been in handling complex physical simulations due to their emphasis on graphics rendering rather than general-purpose GPU (GPGPU) operations. WebGPU, designed to provide modern 3D graphics and computational capabilities, offers significant improvements through parallel processing and support for computational shaders. In this work, we implemented a cloth simulation system using the Mass-Spring Method within the WebGPU framework, integrating collision detection and response handling with the 3D surface model. First, comparative performance evaluations demonstrate that WebGPU substantially outperforms WebGL, particularly in high-resolution simulations, maintaining 60 frames per second (fps) even with up to 640K nodes. The second experiment aimed to determine the real-time limitations of WebGPU and confirmed that WebGPU can handle real-time collisions between 4K and 100k cloth node models and a 100K triangle surface model in real-time. These experiments also highlight the importance of balancing real-time performance with realistic rendering when handling collisions between cloth models and complex 3D objects.
