Alexei Milovidov, co-fondator al SGBD-ului ClickHouse, cu ajutorul asistentului AI Claude, a publicat un sistem de trasare a razelor realizat \u00een \u00eentregime \u00een limbajul SQL. Redarea cu simularea ilumin\u0103rii pe baza tras\u0103rii razelor este implementat\u0103 sub forma unei singure interog\u0103ri SQL, f\u0103r\u0103 func\u021bii utilizator (UDF) \u0219i f\u0103r\u0103 a conecta cod extern. Pentru generarea graficii, se folose\u0219te func\u021bionalitatea SGBD-ului ClickHouse de a salva rezultatele interog\u0103rilor \u00een format PNG. Proiectul func\u021bioneaz\u0103 corect \u00een SGBD-ul ClickHouse, dar cu erori separate \u0219i poate fi de 33 de ori mai lent \u00een SGBD-ul CedarDB. Proiectul este distribuit sub licen\u021ba Creative Commons BY-NC-SA.<\/p>\n

Fiecare pixel reprezint\u0103 un r\u00e2nd \u00eentr-un tabel, care con\u021bine coloane cu coordonatele (X, Y) \u0219i reprezentarea culorii (R, G, B). Opera\u021biile matematice necesare pentru calculele 3D sunt bazate pe tuple \u2014 un vector este codificat ca Tuple(Float64, Float64, Float64).
\nUn ciclu pentru modelarea reflexiilor multiple ale luminii de la suprafe\u021be este realizat prin func\u021bia SQL arrayFold \u0219i este executat \u00een interiorul fiec\u0103rui r\u00e2nd pentru a permite paralelizarea red\u0103rii. Printre primitivele geometrice se suport\u0103 cilindri, toruri, sfere \u0219i paralelipipede orientate, asupra c\u0103rora se execut\u0103 opera\u021bii de unire \u0219i diferen\u021b\u0103 (eliminarea intersec\u021biilor). Peisajul este generat matematic.<\/p>\n

Anterior, dezvoltatorii SGBD-ului ClickHouse au preg\u0103tit un joc similar cu Doom scris \u00een SQL, un emulator RISC-V \u0219i un sintetizator de muzic\u0103.
