1. Fastest way to get points count from geometry with Python. At now I simply use int(hou.hscriptExpression('npoints(“%s”)' % sop_path))

2. Is it possible to get Edit SOP ‘Apply’ button press count?

len(hou.node(sop_path).geometry().iterPoints())

I think it is not faster than hscript expression

Define faster. Faster to type? Faster to execute?

That's the correct way to query the number of points using Python and also the fastest to execute, because it's instant.

Ok. Can you prove that it faster in execution?

What is nearpoint expression function python analog?

findClosestPoint(pos3) → hou.Point or None

This method is not yet implemented.

Ok. How to know that user modified geo with Edit SOP? Node.cookCount() is very different. Even changing soft radius change cookCount

It runs in a millisecond for a 100 million point mesh, is that proof enough?

As you've noticed, the nearpoint equivalent is not implemented and thus there is not one. You could write your own using inlinecpp or could try a numpy/scipy approach like this: https://github.com/captainhammy/Houdini-Toolbox/blob/master/python/ht/geometry/pointcloud.py [github.com]

Since the cook count just cares how many times the node has recooked it's not going to be reliable. I'm pretty sure there is no way to get the information you are looking for.

I was joking ) I can`t measure difference

Good idea, but I need python solution for crossplatform. Maybe when Houdini distributive for Windows will contain compiler )
IMO in my case nearpoint expression is better way

I found solution to check dirt Edit SOP.

if input_geo.averageEdgeLength() != edit_geo.averageEdgeLength():
print ‘Changed with Edit SOP’

I forgot about intrinsic values:
geo.intrinsicValue('pointcount')

Is it possible to unset “Draw Realtime” in Stroke SOP with Python or hscript?
