Hi.
I saw this topic and tried to figure out how it works

Creating simple tornado motion using pointcloud

And I had a few questions:
1. In vopsop1 he create a parameter edge_dir and create a new attribute. How Houdini understood what he had in mind.
2. In voppop1 why he use two global variables and two point cloud open.
3. In voppop1 why he use rampparam if it's not connected to outputs.

Thanks in advance.

1) Edge_dir and edgef attributes were created by Point SOP right before vopsop1.
2) it is not necessary, maybe forgot to delete. You can use only one pcoopen and globs.
3) see 2)

Thank you.
Removed all unnecessary, it became clearer.
Maybe you say the best way to learn VEX, not just read the help.
