Implementing Data-Parallel Stroke-to-Fill Conversion on Modern GPUs

This paper presents a GPU-based, data-parallel algorithm for converting 2D Bézier paths into flat geometry suitable for real-time rendering. The implementation leverages compute shaders across Metal, Vulkan, D3D12, and WebGPU to handle both filled and stroked primitives efficiently. By unrolling recursion and encoding path data into compact GPU streams, the approach minimizes CPU workload while ensuring strong geometric correctness for complex SVG strokes and fills.
