Tree's Trunk clean shape and branch modeling question (L-system)

Recommended Posts

Posted (edited)

Hello,

After a few tutorials and google I can create a basic tree from the l-system

But the thing is the trunk mesh is quite not clean and has some twisted areas,

And the connection between branches to the trunk is not natural for closed up shot.

So my question is Is there any way to get a clean shape from the l-system?

If i used the skeleton from the l-system to generate the mesh then some area on top has missing connection and the polygon number rises dramatically

If I use labs tree generator then the trunk has some twisted areas in the middle and i dont know how to put the branch in the right position 

Also tried to create vdb from it, but it will increase polygon number dramatically

The goal i looking for is the  first image
 

Thanks for any advice

There are different way but at least one really easy which is probably enough for most case if you don't want to make thing to complex or go the volume>pol way.

Just rebuild the curves network from bottom to tips.

See, it's what you have on the right, have what you will get on the left. You could adjust...

Sorry Can you share me a hip example of how you rebuild the curves?

Because these curves come out of the L-system so it constantly changes

So I guess the rebuild proccess must be procedural
