delete group of primitives based on bound box volume

Recommended Posts

hey!

I have thousands of primitives and I need to filter them and delete the ones that has a bounding box volume bigger than a certain value, I tried the measure sop but no luck, at the moment what I'm doing is a very tedious procedure of playblasting one for each frame based on their name and review the playblast to spot the bigger ones, but I know there must be something smarter...

// Delete all prims with area bigger than a threshold
if(primattrib(0, "area", @primnum, 0) >= chf('Threshold')){
            removeprim(0, @primnum, 1);}

This primitive wrangle will delete all primitives which have an area bigger than a certain number. Do you need to use BBOX volume instead of the area or this will work fine?

If you need to delete them based on the biggest size in the whole timeline you'll need to use a Solver of some kind to get the biggest possible bounding box. See below.
