View Full Version : Bar code scan

07-23-2011, 10:56 PM
Hello all,

I'm looking to animate a barcode scanning for a quick animation. I want kind of a fog effect, red laser changes to green (think: accesss granted). Kind of cheesy but nothing too fancy. I've toyed with 1 poly illuminated techniques, but wanted to ask the forum for recommendation or tutorial link before committing.

I think I'd start with an illuminated poly with maybe a smoke or turbulence procedural in the transparency channel to make it resemble a laser in smoke. I might also move/vibrate the poly slightly, quickly (<2 or 2 frame animation) with motion blur on to give it a little depth.

I might also try a volumetric light with a smoke or turbulence texture (texture only mode) one a spot light that's projecting an image of a line, but I think I'd try the poly method first.

thanks for the advice. It came in handy.


This ended up being the result. I went with a volumetric spotlight and a projection image of a red horizontal line.
