File talk:Parallax barrier vs lenticular screen.svg

Latest comment: 12 years ago by Cmglee

Cool illustration. (with those semitransparent surfaces and outlines) How did you make it - is it drawn or really 3D? ...Or a combination of those two?

Thank you! It was "drawn" in Notepad++ by manually entering the Scalable Vector Graphics code below. The 3D effect is similar to the dimetric projection used in older video games. cmɢʟee☺τaʟκ 18:45, 16 June 2011 (UTC)Reply
