摘要:

本工作提出了一个基于Web的开源路径追踪器,使用WebGPU和OpenPBR表面着色模型渲染基于物理的3D场景。自2011年WebGL引入以来,光栅化一直是Web上主流的实时渲染技术,但它在全局光照方面存在困难。这需要更复杂的技术,通常依赖预生成的产物来达到所需的视觉保真度。路径追踪本质上解决了这些限制,但代价是渲染时间增加。我们的工作专注于高度可定制产品常见且实时性能不关键的工业应用。我们利用WebGPU在Web上实现路径追踪,集成OpenPBR标准进行基于物理的材质表示。结果是一个近实时的路径追踪器,能够直接在Web浏览器中渲染高保真3D场景,消除了对预生成资产的需求。我们的实现展示了WebGPU在高级渲染技术中的潜力,并为工业应用中基于Web的3D可视化开辟了新的可能性。

英文摘要:

This work presents a web-based, open-source path tracer for rendering physically-based 3D scenes using WebGPU and the OpenPBR surface shading model. While rasterization has been the dominant real-time rendering technique on the web since WebGL's introduction in 2011, it struggles with global illumination. This necessitates more complex techniques, often relying on pregenerated artifacts to attain the desired level of visual fidelity. Path tracing inherently addresses these limitations but at the cost of increased rendering time. Our work focuses on industrial applications where highly customizable products are common and real-time performance is not critical. We leverage WebGPU to implement path tracing on the web, integrating the OpenPBR standard for physically-based material representation. The result is a near real-time path tracer capable of rendering high-fidelity 3D scenes directly in web browsers, eliminating the need for pregenerated assets. Our implementation demonstrates the potential of WebGPU for advanced rendering techniques and opens new possibilities for web-based 3D visualization in industrial applications.
