(About the author)

This program uses the concept of fractals in nature and generates realistic Trees using recursion ( the recursion part is heavily commented ). Each branch can be thought of a small tree on its own and every other branch on that branch. Hence this program uses the concept of recursion very effectively in creating trees

Very cool, and very nice example of 
recursion

5/29/2001 2:35:11 PM:Mike Canejo

Very nice...

Good work. Nice recursion example. I 
gave you a "4" instead of a "5" because 
you need some bounds checking to 
prevent overflow errors. I got several 
while fiddling with the complexity. 
Otherwise, good job!

Beautifull :)

The leafing is superb!  The branches 
make it look fake :(   Other than that, 
nice recursion and tree!

5/30/2001 12:33:19 PM:Vitaly

Way to go!

5/30/2001 3:03:44 PM:SniperBoB

VERY NICE! This is so cool, but now the 
problem is converting this to 3D and 
being able to create low poly, 
somewhat-realistic trees for a D3D 
game's level editor  :-)

5/30/2001 3:08:52 PM:SniperBoB

oh yea, I love that font thing, Great 
idea! Also u got an excelent from me!

Everyone seems to be interested in the 
recursion but I already know how to 
utilise that. What really impressed me 
is the fractal element, I'm totally new 
to using fractals so this is 
fascinating to me. 5 globes.

The branches look a bit fake, too 
calculated. Also you need some error 
handling, how many times did I get 
overflow errors when playing around 
with it, quite alot. Otherwize very 
cool. 4 globes, 5 if it hadn't been for 
the errors and the fake looking 
branches. Lets see if you can generate 
a landscaped garden scene, make flowers 
and different types of trees, theres an 
idea for you. ;)

Amazing i gave you 5 out of 5 the tree 
looks basically real if you hind the 
trunk 
Just amazing!!!

6/18/2001 7:17:07 PM:Martin

Great Job, but you forgot the 
autoredraw on the rendering windows

6/18/2001 9:45:06 PM:Terry Smith

Excellent work. Needs error handling, 
auto screen clear and better branches, 
but otherwise excellent!

6/18/2001 11:04:25 PM:Jason

I managed to fix the overflow error by 
changing Dim prog As Long to Dim prog! 
in the declarations section of Form1 
(tree.frm)

I have also made a tree drawing program 
tho much simpler.  Search for graphical 
tree

8/21/2002 8:14:26 AM:Dragonfly

Try putting in some random numbers to 
keep the branches from propagating all 
the same way, otherwise, looks very 
nice.

8/21/2002 12:44:59 PM:Vi11

Excellent.  I gave you a five even with 
the overflow errors. Visually stunning.
