ClickHouse renders ray‑traced graphics using only SQL
ClickHouse now ships a path tracer written entirely in ClickHouse SQL, outputting PNGs with shadows, reflections, and animated text—all without UDFs or external code. The renderer lives in a single SELECT, leveraging vector tuples and array folds to parallelize computation across CPU cores. It proves a column‑store can handle graphics‑heavy workloads, expanding what engineers consider possible inside a database.
