21 Aug 2009 : Cog animation
This cigarette crushing device forms part of an anti-smoking site for Pfizer. Animating the cogs conventionally proved impossible as there is no point where you can loop the animation and have the cog textures match up, they had to be animated using a tween engine(TweenLite). The initial problem was to ensure the cogs rotated at the correct speeds to 'mesh' as they would on a real machine. This is achieved by counting the number of teeth on each cog to work out the gear ratios. In the case of this animation I decided I wanted to rotate each cog 100 times and using the gear ratios I could work out the time it would take each cog to complete its rotations, and hence everthing stays in sync. Adding the cigarettes posed the usual set of problems when integrating timeline animation with actionscript animation, but it worked out well in the end.
