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:

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 :

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

Cheers
