bottle rotation, best approch

Recommended Posts

Hi guys,

I'm wondering how to get the best approch for rotating a bottle on border and then stabilize in a realistic way? rotation slowly and then faster to then stibilyze..

 

Thank you for your help.

This is my attempt... seems to work. If there's a better way, I'm open to discussion :)

 

Thank you

sooooo...isolation leads to spin the bottle hey.....nudge nudge wink wink...:wub:

hey here's my ludicrous attempt...I've tried loading the bottom with geo...or cheat with wider base....it's bloody fun tho....could be here all night !!!

this works....but it looks too lame to me...careful with 'sleep' it might stop too suddenly.

Where's Murray Walker when you need him....spin spin spin..round round round...

ahhhhhh......got it....all you do is use a torus/disc instead....that way, it always lands flat...then use the torus as a proxy to drive the bottle.

(just hope it doesn't turn the bottle upside down that is)

if you pack your bottle before feeding into solver you can add attributes i@computecom=0 to disable automatic computation of COM and  v@pivot to adjust where the actual COM will be
