WebSplatter: Enabling Cross-Device Efficient Gaussian Splatting in Web Browsers via WebGPU

WebSplatter is a new GPU rendering pipeline designed specifically for the web, addressing the challenges posed by diverse hardware environments. By implementing a wait-free hierarchical radix sort, it effectively manages the limitations of WebGPU's lack of global atomics, ensuring consistent performance across different devices.

For developers, especially graphics programmers, the ability to achieve 1.2x to 4.5x speedups over current web viewers means more efficient rendering and reduced resource consumption. The opacity-aware geometry culling stage further enhances this by minimizing overdraw, which is crucial for optimizing memory usage in web applications.
