Morphogenesis in Houdini

Amazing! I tried to implement this recently too, and didn't get anywhere near these results.

I guess i'll be the cheeky one ask if you could share a hip file, or maybe an explanation of the steps you took to get it working.

I found the largest challenge to be cell splitting for which I needed to implement in-order neighbor traversal:

Let me think about sharing the HIP file. It was a fair bit of work but ultimately nothing particularly special.

Thanks Activate! Totally understand about the hip. In some ways, i'll learn more by doing it myself anyway.

Thanks for the code, and congrats on the result!

I have no chance of recreating this myself :-D
So... share some new morphsogenesii!

I finally got around to cleaning up the hip file and have attached it. If you end up using this, please let me know how it's going and share a pointer to your work.

The major challenge with writing this in VEX was that VEX does not offer any of the canonical data structures one would use to efficiently implement this. For me, the simulation ends up running out of memory around a 1000 frames. As I am novice to Houdini, I would also appreciate any feedback and comments you might have if you end up taking a look.

Enjoy? :-)
