-Along with moving the camera horizontally it's critical to also have the camera focus on one point in the scene. If you're using three.js - there's a simple camera.lookAt(object) method which allows for this 'focus' very easily. Wherever your camera is focused will become the middle ground in your 3D scene. Things further than this focus point will seem to fall into the lenticular and things closer will pop out of the lenticular. If you are rendering an image of a human head - you may want the focus point to be the center of the head so that the nose and forehead stick out of image and the background recedes into the distance. If you want the head to appear inside the lenticular then use the tip of the nose as the focus point.
-After you run the program, open your final output in photoshop and go to Image > Image Size in the top menu. In here, uncheck resample and make the resolution to 300dpi (Processing outputs it at 72dpi naturally). Unchecking this will allow for the pixels to remain unchanged and keep everything crisp for the printer. F

 ====== Printanje ======
-Lenticular is a HIGH RESOLUTION process as the lenticular sheet is magnifying the data that is printed to the backside of the lens. Our clients are offset or digital printers, printing at high res. like 400 LPI or even more.
+Ovakav tip slika zahtjeva vrlo visoke rezolucije s obzirom na to da su lentikularne folije povećavaju sadržaj koji se nalazi ispod njih.
+.4 mm / 50 lpi = 0.508 mm
+leća = 0.508 mm / br. //frame//-ova!
-Potrebno je isprintati sliku na točno definiranoj dimenziji ili rezoluciji (tekstuali file uz generiranu sliku), u protivnom slika neće biti funkcionalna. Osim toga, moguće je da sam printer doprinosi malim pomacima pa se ponekad mogu dobiti bolji rezultati ako je još ručno poštima (poveća ili smanji) slika.
+Kako bi efekt bio uspješan potrebno je isprintati sliku na točno određenoj fizičkoj dimenziji ili rezoluciji. Program generira tekstualni file uz sliku u kojem se nalaze sve potrebne informacije. Osim toga, moguće je da sam printer ne preproducira savršeno precizno standardnu rezuluciju, pa se ponekad mogu dobiti bolji rezultati ako je još ručno poštima (poveća ili smanji) slika.
