[Plugin] Sketchup Ivy

Pierreden · 25 Apr 2011, 13:02

After playing with "An Ivy Generator"(found here ) I thhought about how awesome it would be to be able to play with something like this directly in Sketchup. I therefore started to port the ivy generator to ruby and Sketchup. As i now have working code with regards to the main parts of the algorithm, collition detection, adhesion and the growing of the ivy branches, i decided to post a proof of concept.

Usage
-Select "Sketchup Ivy..." in the Plugins sub-menu
-Adjust Parameters in Menu
-Every time you click your left mouse button, the ivy will grow
-CTRL-Click for leafs (repeat as many times you want)
-When you're happy with the ivy Shift-click to make it into actual volumes.

Please get the latest version's RBZ from the PluginStorehttp://sketchucation.com/pluginstore?pln=SketchupIvy Now suitable for all OSs and SketchUp versions from v8 through to v2015...

VERSION 0.6
UPDATE 12.05.2011
-Tooltip
-Minor bug fixes
-Additional parameters.

VERSION 0.5
UPDATE 09.05.2011

Will now use components with "ivyleaf" in the name as leafs. 3 included by default.
Hopefully better mac support
Small algorithm changes
ALT+click to make ivy grow towards pointer
- Thea users: uncheck 'export as components' before exporting. (Thanks Solo)
Fix 0.5.2
Tool startup fix (maybe?)

VERSION 0.3
UPDATE 05.05.2011

Simple gui. (More parameters to come)
Leaves
Speed and reliability
I know theres some issues with mac. As i haven't had the opportunity to debug on a mac, im not sure if its working now. Mac users with issues are very welcome to PM me or write here. (Guess this goes for everyone with issues, im sure there is lots ).

VERSION 0.1.5
UPDATE 28.04.2011
[Uploaded buggy file !! Sorry]

Added Wind (comming from the position of the sun atm)
-Bug fixes

VERSION 0.1
UPDATE 27.04.2011

Faster Preview
Better Ivy "Resolution"
Faster and more reliable volume generation (less buggsplats?)
Face normals should now be oriented correctly
More reliable collision detection
A few bugs in the force algorithms fixed.
Works as before. Edit the values in Plugins/SketchupIvy/setup.rb

TO COME

Leaves as Components
More Parameters and grow patterns.
Other Plugins. Fur, Cloth and Tree.

Notes

Never shift-click when there is more than 150 branches (information in the ruby console). This will often cause a bugsplat (seems like sketchup realy, realy, realy doesn't like programmaticaly adding of entities or seemingly infinit loops )
For the adhesion to work, you have to be in the same scope (i made this to clearify (face.classify_point seems buggy)
This script has only been tested in SU8. As far as i know this script might cause bugsplat infernos and generally fuck shit up in other versions
If you find any bugs or problems please PM me If you're extra awesome attach the error description from the ruby console.

Any suggesions, comments or crits are very much welcome!

Peace
Pierre

Thanks Pierre, Could this be the new 'Fur'?

I havent realy seen the connections before now, but i guess this algorithm is sort of like "fur branching of furs". I believe tha changes needed for this to behave as fur is minimal! brb

nice! thanks for this! finally an ivy generator inside sketchup!

Great. I will surely be following this thread.

hi,

im working on a mac, the plugin doesnt seem to work at all in niether Su 6,7 nor 8

Download link sends my virus software into a tizzy, anyway to host it elsewhere?

Thats not good. I would really appreciate it if you could PM me the error message you get in the ruby console (Window - Ruby Console)

Hi Pierre,

Great plugin. We normally add the [Plugin] tag to the title to help search/identify plugins. Just edit your original post. You can also edit the original when you update version numbers so members can see it's been tweaked.

Great to have you around SCF

solo · 25 Apr 2011, 21:15

Thanks.

Okay it works fine. I will wait for the leaves however as at moment it looks like a growing spider.

A GUI would be awesome and if qnything like Ivy generator which can follow a profile like an arch would also be brilliant, as well as gravity/adhesive controls

Great start.

Very interesting project. I'll give it a whirl when I get time and maybe poke about in the code. Ivy generator is something I've wished I had on several projects.

Gaieus · 25 Apr 2011, 22:11

Hi Pierre and indeed it seems to be a very exciting project.

I've been making ivy with the fur plugin so far but a more straightforward and "real" ivy generator would be much better of course!

Any chance to attaching the file straight to the first post though? Some member have issues with this, others with that file hosting services (some are not accessible in certain countries) etc.

(Surely I cannot tella script author where to host his plugin - just suggestions for easier use)

Thank You!

Very interesting start. Just to get the coder's cog wheel whirring; you realise of course that a random growth generator has implications way beyond just ivy? Especially if it has a GUI that allows you to control variables like the upper limit of vector change, the amount of branching and taper, number of segments per limb etc.
Obviously, Follow Me won't follow a branching path...but there is a Max plugin called Branches that generates a single, random, tapering limb. What you then do is click on a joint higher up; and it shoots off another branch, taking the overall scale of this offshoot to be based on the now (reduced) diameter of the original limb at that point. Now that would be really something.

[Edit} 20 minutes, 1 cup of coffee and 1 V-Ray render later. This is a very useful plugin, even in it's early stages.

Wow. Thanks for all the replies!

@Gaieus: Of course. But is it possible to attach a rar file directly to the post?

@Alan: Yes. That seems brilliant! (one day It really seems like this Ivy algorithm has a lot of potential (way beyond ivy). And in regards to what you said about gui, this is what i have in mind.It is scene-aware and quite easy to customize. Last night I rewrote a chunk of it , added an external force (wind, comming from the sun) and tried to make it a bit more aware of the scene. After some tweaking it realy looks like a good Fur plugin - (screenshots below). I guess it wouldnt be too hard to make it in to a tree growing algorithm og even combine these into a powerpack of branching awesomeness.

Pierre

Yes - under the textbox when you write a post there is an "Upload attachment" tab where you can upload files.

Hehe, sorry about that. Latskap.

Gaieus · 26 Apr 2011, 12:11

And I have just checked; the extension "rar" is also allowed (I thought maybe that's the problem).

Sergio Morera · 26 Apr 2011, 16:05

Thank you for your generosity. I look forward to give it a try
