The rendering with light simulation based on path tracing is executed as a single SQL query without user-defined functions (UDF) and without connecting external code. The ClickHouse DBMS's ability to save query results in PNG format is used to output graphics. The project functions fully when run in ClickHouse, but with some errors, may operate 33 times slower in CedarDB.
