Introduction
Here is an addon for Blender which generates ivy on objects. It is a port of the well known standalone program Ivy Generator (http://graphics.uni-konstanz.de/~luft/ivy_generator/) which has been made with the permission of the original author Thomas Luft. It is also a continuation of the efforts of Blender users testscreenings and PKHG.

Where dir i put the ivyGenerator.exe ? it still need or not
This is an error message I got as well- but hey, it is Beta.
@ TrumanBlending
The python-API documention seems not to have any description about any property “closest_point_on_mesh()”.
Are you using a different built than the standard 2.58a?
TrumanBlending, you’re my hero !
Having ivygenerator directly within blender is really usefull, even more provided the original program doesn’t work anymore (at least for me, on linux).
Apologies for the confusion, I should have stated that you require a build after r38449 to use this script. closest_point_on_mesh() was added at that revision.
I pulled down the latest build r38533 and the script does run, but using the default settings that pop up seems to produce an infinite loop. It has been running for over an hour and still has produced no results.
What are some “good” settings to use for quick results?
PS: The pop up is annoying feature. So I put my settings in and then go to the bottom of the popup to click the Ok button and I missed with the mouse and the popup disappeared. Sure enough, when I run it again I have to put my settings in all over again. This script would benefit from having all those parameters in the Tools panel like traditional scripts. IMHO.
Thanks for the feedback and an update has been made to hopefully fix this. I believe the infinite loop problems were most likely caused by the starting point being too far from the surface or exactly on the surface. Let me know if the update helps. Also please note that “Gravity Weight” should not be set to 0. This will be fixed soon.
Not sure if this is a bug : when I launch this addon via the search panel -> IvyGen, the popup appears, but when I click “ok” nothing happens.
When I use add -> curve -> Ivy, it works fine though.
Investigating ourself!
The basis is not from truman or pkhg, only ‘adjusted’ to the newest version
Here is ‘my’ test version https://svn.blender.org/svnroot/bf-extensions/branches/ivygen/pkhg_ivy/
With menu panel in the toolshelf of View3D to see effects of changing parameters! (and a time limitation is build in to prevent an infinite loop)
EDIT
Still available but use the link TrumanBlending refers to (22-7-2011), is THE version.
Version 0.02 seems to have some problems. I pulled the script down and pasted it into a text window. When I run the script it no longer appears in the View 3D/Add/Curves menu, like the previous version did. So I pressed space bar and typed ‘ivy’ in the search box and it did show up. I assume as an operator because when I clicked on it in the search box it simply ran without offering up any chance to change or set parameters.
