Hey everyone! In this video, we're discussing two very useful VEXpressions that will come in especially handy for simulations (but not only!):
bbox
centroid
We will also have a look at a bounding box workflow that can be used for every simulation and explore the uses of:
trail SOP
timeShift SOP
bound SOP
$FSTART & $FEND
You can use this knowledge not only for simulations but also for any procedural networks and tool creation in Houdini.
I'm using Houdini version 19.5, but the same will work in any Houdini version.
Thank you for joining me today and I hope you find the video useful! 😊

If you came to the end of this description, well done! I've got a question for you: "Does your laptop try to fly away when you run a simulation?". Mine definitely does as you can hear towards the end of the video!
