I'm exploring something akin to this, but focusing on 3D views via mesh shading, also powered by DuckDB. Can you describe your cortex mapping data sources (volumetric? approx number of samples?) and is there any open data to grab? What kinds of visualizations/manipulations you would want or is there an existing product to compare to? Thanks :) EDIT: Confused WGPU with WebGPU, so deleted a sentence.
