From Vivec Website,
I’ve been wanting to do something for the 3d community for a long time now. Unfortunately, I don’t have enough free time to create anything useful from scratch. I was working with Thomas Luft’s Ivy Generator for some scenes and even though it’s awesome, it was pretty slow to create ivies (it was using a single core). He was kind enough to provide the source of the program so I decided to take a shot at accelerating it.
Ivy generator is now fully multi-core optimized. It is 2.5X faster on a single core and an order of magnitude faster on 4 cores. As far as I can tell it is very stable. I’ve also updated the Qt and OpenGL libraries.
I want to thank Thomas Luft for creating this very useful tool, all the credit belongs to him. He has a donation page here. If you find the program useful, please consider donating.
