Malo uvoda<\/h3>\n

\nJezik Vex odvra\u0107a po\u010detnike korisnike Houdinija. U velikoj mjeri zahvaljuju\u0107i njemu stvoren je stereotip da je u Houdiniju obavezno kodirati. U stvarnosti, u Houdiniju je mo\u017eno<\/i> kodiranje olak\u0161ava i ubrzava mnoge procese, a ne ote\u017eava ih. Na primjer, poma\u017ee izbje\u0107i ovakve zastra\u0161uju\u0107e postavke: <\/p>\n

\nJezik Vex je stvoren za pisanje shader-a u renderu Mantra (ugra\u0111eni renderer programa Houdini), ali je prili\u010dno brzo iza\u0161ao iz okvira prvotne upotrebe zahvaljuju\u0107i svojoj fleksibilnosti, jednostavnosti i brzini. Naziv jezika dolazi od skra\u0107enice Vector EXpressions, ali se uz njegovu pomo\u0107 mogu manipulirati potpuno razli\u010ditim tipovima podataka. Tako se Vex prvenstveno koristi za razli\u010dite vrste manipulacija komponentama geometrije (to\u010dkama, poligonima), kao i za proceduralno stvaranje geometrije.<\/p>\n

Jezik Vex je prili\u010dno tolerant\u010dan prema sintaksi i formatiranju koda, i ima prili\u010dno nizak prag ulaska. \u010cesto je dovoljno nekoliko redova da se postigne \u017eeljeni rezultat. Me\u0111u njegovim prednostima su tako\u0111er vi\u0161edretvenost i, posljedi\u010dno, dobra brzina. Programiranje na Vex-u potrebno je za rje\u0161avanje osnovnih zadataka kao i za slo\u017eene i komplicirane prora\u010dune, i sa svime tim jezik se nosi izuzetno brzo. Uz njegovu pomo\u0107 mo\u017eete raditi mno\u0161tvo zadivljuju\u0107ih stvari u proceduralnom modeliranju, animaciji i simulacijama.<\/p>\n

Naravno, svi\u0111a nam se kad netko misli da smo svi programeri, ali u stvarnosti smo navikli na funkcionalnost i prakti\u010dnost (iako mnogi, kada prvi put rade s Houdinijem, mogu pomisliti da je udobnije samo spavati na \u010davlima). Da neki alat ne olak\u0161ava na\u0161 \u017eivot, ne bismo ga koristili. Stoga ne treba shvatiti mogu\u0107nost programiranja kao ne\u0161to \u0161to ometa po\u010detak u\u010denju Houdinija. Vex je samo jo\u0161 jedan (iako vrlo dobar) alat me\u0111u mno\u0161tvom drugih.<\/p>\n

Python, much more widely known, doesn't need much introduction or detailed description. Let's discuss why it's important to us. In the context of Houdini, Python is used to control the program itself (creating nodes in a project, managing files, automating repetitive tasks, reproducing complex combinations of actions, etc.). Additionally, programming in Python is needed for creating beautiful interfaces in tools and writing convenient commands to manage assets with a click of a button. If there was a button in a Houdini asset labeled 'make it beautiful', it would be written in Python. Furthermore, it's sometimes used for manipulating geometry (just like the Vex language), but it's important to understand that Python is less intuitive for such purposes and often performs this task slower than Vex. <\/p>\n

\nThe developer of Houdini, Side Effects Software, releases so many updates and provides so many opportunities for users that the official documentation and training courses simply can't keep up. Therefore, we are collecting information piece by piece from various sources (paid, free, official, and unofficial) to thoroughly master these flexible and powerful tools \u2014 the programming languages Vex and Python (and Houdini as a whole). We chose courses from Mix Training because they offer a comprehensive coverage of material on Python and Vex in Houdini.<\/p>\n

The course author has kanal na YouTube<\/a><\/noindex> a decent resource for those looking to start learning Houdini, characterized by a laid-back presentation and a wide range of topics, from motion design to game development. Besides the channel, he also has his own garage death-metal band. We decided that the author is trustworthy, so we purchased Priroda Vex-a<\/a><\/noindex> in Zalogaji Pythona<\/a><\/noindex>, with 8 hours per course (can be viewed at a speed of 1.5). <\/p>\n
