Full Version: climbing plant in 3d

Hi guys,

I would like to create a climbing plant in 3d on which to apply a texture with opacity to simulate real leaves.

Is there a command that randomly generates leaves (represented in random rectangles)?

---

You can use this "random selection" for some tricky things
You can change the "30" who is here 30%

script: /* Random selection of objects from a selection */ var percent = 30; var objs = moi.geometryDatabase.getSelectedObjects(); for ( var i = 0; i < objs.length; ++i ) { if ( Math.random() * 100> percent ) objs.item(i).selected = false; }

and also Dispersion by Max Smirnov ! http://moi3d.com/forum/index.php?webtag=MOI&msg=6486.1

So you propagate vectors along curves ( _vSeed) then objects on these vectors! ;)
(take a tortured surface as alignement of vectors)

Hi Tony,

re:

Not that I'm aware of. A couple of programs to try:

In the free SketchUp make 2017 you have this crazzy "Sketchup" Ivy by Pierreden!

---

But the best is nothing to do and use something like the Free TwinMotion :) (if you have downloaded it during the last year! )

---

Else with the _Vclone above by Max Smirnov ;)

Of course you can take any objects (volumes, surfaces, curves) here a simple rectangular surface :)
And the scale of the objects can be adapted to the "vectors sizes"!

So the only difficulties is draw the vectors on the branches!
Here vectors have the same size so rectagles also !)

---

So problem resolved :)

---

Thanks Michael and Pilou

Pilou I tried Vclone but I can't create multiples of the same object I only create one object on the path

---

You must select all "vectors" drawn along the path! (like on my video above) ;)

So select all (Brunches + Vectors) then deselect brunches...

you will obtain your leaves resized like your different vectors...

At the end kill the vectors

Et voilà...

---

But do vectors have to be drawn separately with a series along a curve?

---

You draw your vectors (a simple line with many sizes if you want) anywhere you want!

Of course along a curve will simulate a branche :)

That works very fine...here i have 3 sizes...put a color for a more easy selection...

This a node was I was working on based on this example:

http://jsfiddle.net/GertG/gv2z9r72/

It is in 2D. Adding a third dimension is a future development potential for someone. :-)

The switch is for a new random generation of the branches.

@ Wayne

Will be fine if the last lines extremities will be on a different color!

for working with the _Clone! ;)

Now i must select by hand...some painful :)
And difficult do not take branches against last extremities!

Here some white apples :)

Hi,

For me the best option for what you asking for would be to use Blender with specific addons.

Have a look there :

https://www.blender.org/download/

https://inspirationtuts.com/blender-plants-addons-vegetation-asset-packs/

https://blender-addons.org/vegetation-addon/

I do love nurbs based software like Moi3D that i use often, but unfortunately nurbs have some limits for some tasks.

Cheers
