Hi there,

I would like to know how to get the number of points inside of the point cloud search radius. Any advice would be appreciated.

Thank you.

attached a file for you, it's easy!

cheers,

Manu

Hey Manu,

This is awesome and really helpful!

Thanks!!

it's even easier
it's called Point Cloud Num Found VOP, just connect handle to it and it will return number of found points within radius and max point count limits set on pcopen

this function is available from H12 though so in H11 you still need to count them in loop

thanks for mentioning that! Do you know if there is a vex equivalent as well?

it is pcnumfound()

Houdini 12.0.517: New VEX point cloud functions pcnumfound and pcimportbyidxFOO, with corresponding VOPs pcnumfound and pcimportbyidx. These allow processing of point cloud searches using a For VOP rather than black magic and ritual sacrifices.

I included example of usage of both functions to For Loop through pointcloud instead of While Loop in this post

appreciated man!
