Centroid of group with expression? (Create point at center of a group)

Recommended Posts

Hi!

 

I have basically the same question as this, but with a different goal:

https://www.sidefx.com/forum/topic/50237/

I too wonder if there is a simpler way than 'group > delete > centroid the delete', but I would like to do it with a expression rather than a local variable. 

This way I can create a point in the center of a group in the Add node.

 

Help or other suggestions would be appreciated!

If you Pack the group you should get a single point in the center. Then Add SOP set to 'Delete but keep points':

If you 'middle click' on any node, there is a lot of info, also a center position which you can strip out in many different ways"

- like an answer from sidefx forums: $CEX/$CEY/$CEZ

- or expression centroid("../node/path", D_X), centroid("../node/path", D_Y), centroid("../node/path", D_Z)

- or vex "getbbox_center()" function. https://www.sidefx.com/docs/houdini/vex/functions/getbbox_center.html

- or retrieve prim intrinsic bounds, substract min from max and divide by two.

 

... and probably 5 more other ideas ;]
