Este repositorio explica como generar directamente un archivo PNG mediante PNGel formato de salida de ClickHouse. Sin funciones definidas por el usuario ni código externo: un único SELECT cálculo procesa cada píxel.
OBJETIVO:
Quiero que generes un PNG de un pelícano en bicicleta a partir de ejecutar la SQL tal como muestran en el README.md .
Quiero que el pelícano en bici circule por el rio, con un eclipse de Sol en horizonte. Cuida mucho los detalles.

Script completedWall time 0.1 secondsOutput: # RayTracer — a ray tracer in ClickHouse SQL  A path tracer written entirely as **ClickHouse SQL queries**, rendering straight to a PNGvia ClickHouse's `PNG` output format. No UDFs and no external code — a single `SELECT`computes every pixel. It renders the word **ClickHouse** as glassy, chrome lettering — in the spirit of AndrewKensler's famous Pixar business-card ray tracer — and, in the scene above, sets it floatingover a procedurally generated landscape, reflecting the terrain and casting shadows on the hills. See also:- [NoiSQL — Generating Music With SQL Queries](https://github.com/ClickHouse/NoiSQL)- [SQL Mandelbrot Benchmark](https://github.com/ClickHouse/sql-mandelbrot-benchmark)- [Click-V: A RISC-V emulator built with ClickHouse SQL](https://github.com/SpencerTorres/Click-V)- [DOOMHouse is a "Doom-like" game engine that renders the 3D graphics entirely in ClickHouse SQL](https://github.com/arniwesth/DoomHouse) ## How it works The whole renderer lives in one query: - **Pixels are rows.** `numbers_mt(width * height * samples)` produces one row per `(pixel, sample)`; samples are averaged with `GROUP BY pixel`, and the output columns `r, g, b` (in `[0, 1]`) plus explicit `x, y` coordinate columns (`pixel % width`, `intDiv(pixel, width)`) are written to the `PNG` output format. The explicit coordinates let the writer place each pixel by its position, so the rows need no `ORDER BY` and the heavy per-pixel work stays parallel across all cores.- **3D math on tuples.** Vectors are `Tuple(Float64, Float64, Float64)`; `dotProduct`, `L2Normalize`, `tuplePlus`, `tupleMultiplyByNumber`, … do the linear algebra, wrapped in short lambda aliases (`va`, `vs`, `vm`, `vd`, `vn`, `vc`, `vref`).- **The bounce loop is `arrayFold`.** Every ray is advanced exactly one mirror bounce per fold step over `range(maxDepth)` — a loop *inside each row*, so rows stay independent and the render parallelizes across all CPU cores. (The first version used a `WITH RECURSIVE` CTE instead — see the queries below.)- **`let`-bindings via `arrayMap`.** ClickHouse `WITH` lambdas are call-by-name, so passing a value as a parameter re-expands the expression and blows up the query tree. Intermediates are therefore bound *by value* with `arrayMap(x -> body, [expr])[1]`, a one-element-array "let". ### Geometry (Constructive Solid Geometry) - **Cylinders** — round rods with flat caps for the straight strokes (`l`, `i`, `k`, `H`, `u`, the bar of `e`).- **Tori** — the round letters (`C`, `c`, `o`, `u`, `s`, `e`), ray-**marched** through their signed-distance field; the openings of `C`/`c`/`s`/`e` are a box subtracted from the ring.- **Spheres** — the dot on `i`, plus a chrome "planet" that is a sphere **minus** a sphere.- **Oriented boxes / parallelepipeds** — available for flat-faced strokes. So the scene exercises boxes, cylinders, tori and spheres, with CSG **union**, **difference**(the planet and the letter openings) and a **ray-marched distance field** (the tori). ### Terrain A height field `z = amp · fBm(x, y)`, where fBm sums several octaves of lattice value-noise.Camera rays are ray-marched against it — the march skips the empty air (it starts where theray first drops to the terrain's maximum height) and linearly interpolates the surfacecrossing, so it is both fast and free of step-banding. It is shaded with a height color ramp(water → sand → grass → rock → snow), a warm sun plus cool sky-ambient model, marched shadows(terrain self-shadow *and* the letters' cast shadows), and distance fog into the sky. ## Gallery **ClickBulb** — a desk lamp built entirely from spheres hops in, leaps behind the banner, rakesits light through the letter gaps, then pokes its head through to peer at you.
