My name is Ros, nice to meet you.
My question is, the Knife tool in Houdini how does work?
in this video (Cinema4D)
First step he uses the knife to carry out the random cuts at the sphere obj.
Knife tool in Houdini works different.
Kind regards
Ros

if it's about cutting only polys that are facing the camera then you can:
enter selection mode
make sure Area Select Visible Geometry Only is on
rect select your geo, note that occluded points will not be selected
enter Knife Tool, make a slice, press Q to repeat slicing until you are happy
all your cuts will be done only on selected polys
