Practical Methods for GPU-Based Map Rendering

The presentation focuses on GPU-accelerated map rendering techniques. While GPUs have evolved over decades to deliver superior efficiency, they are inherently designed for 3D scene rendering and are not naturally suited for 2D/2.5D map graphics. Specialized techniques are required to meet cartographic representation demands. This presentation will highlight three key research contributions in GPU-accelerated cartographic rendering: (1) A novel functional rendering method for line symbols that simultaneously addresses cross-tile width consistency and enables multisymbol single-pass rendering; (2) An advanced texture-reinterpretation technique achieving scalable anti-aliased point symbol rendering and large-scale dynamic flow field visualization; and (3) A specialized underwater terrain rendering module featuring modern platform integration and GPUoptimized bathymetric contour generation. These developments significantly advance the state-of-the-art in computational cartography.
