Ah. This crashes as it calls an infinite recursion.

I used onInputChanged signal to disconnect and reconnect all inputs whenever input contains a None item but Houdini crash constantly in the most recent production build 18.0.416!

This is definitely a step in the right direction. Thanks!

1. the hip file must be opened by Houdini 18
   
2. I choose a simple method to divide the whole lot to piece (the method mentioned in paper need hundreds of nodes).
   And the paper need to combine small area and triangle poly finally, and also need many further optimizations.
   they are all need heavy vex code or complex for-each / repeat loop.
   so I do not achieve those goals in this hip
   
3. I use a HDA created by myself in the hip
   the HDA called “convert_edge_group_to_line”
   you can replace it by labs::edgegroup_to_curve SOP
   or you can download my HDA here My HDAs [drive.google.com]
   

1. try to set v@up = {0, 1, 0}
   
2. try the orientation along curve SOP in Houdini 18 to create orient but not use poly frame SOP
   
3. try the copy to curves SOP in Houdini 18
   
4. try my HDA : Point Orient [vimeo.com] to get orient (or qLib :: orient, also can see in my link)

Absolutely incredible thing. I can't imagine how many time you spent to build this and yes, it's much better than C4D. Also, I found a lot of cool things in archive. You should make patreon channel and place some tutorials and updates there. I am ready to support you

you can use “opinput:0” to access first input's geo using string, it doesn't seem to be working for spare inputs, but from VEX you can access geo of it's inputs directly within compiled network

Drag down the slider on the right to see more.

dont count on it, the previews of H18 have the same old curve tool.

I've seen this tutorial but seems really complex for a beginner like me.

@zengchen01 can you explain how do you use it to generate simple roads, or suggest any specific tutorial you follow.
