I've finished new version of POV-Tree. New features:

- icons for leaf type
- more predefined mesh leaves. Now you have leaves from
  one triangle up to 24 triangles.
- custom mesh leaf. You can develop your own mesh leaf in
  POV-Ray and then just cut and paste all triangles into POV-Tree.
  And it will be used by mesh tree generator.
- added three new examples - maple, willow, linden
- bug fixes

I also included TOMTREEm.inc into distribution. This is modified
TOMTREE macro which works about 6-7 times faster.

Right now you can POV-Tree here:
http://home.covad.net/~gobukhov/povtree1.1.zip

Later on I'll update all my homepages and you'll find it in usual
locations.

If you'll face any problem with POV-Tree please let me know.

Gena.

Thanks!
It's not so advanced as professional programs
but it doesn't cost you $500 :)
Hopefully with your feedback it will become
better and better.

Love it!  Love it!  Love it!

I've spent a few hours playing around with POV-Tree, but haven't been able
to move very far past the examples.  We've got quite a variety of examples
now, that really wouldn't need modified very much in order to create a
complex scene with several varieties of trees.  I have a couple WIP's
involving TomTrees, but I've been too busy with other summer-time activities
to finish them.

With all these varieties of trees, perhaps it's time to install another
512MB in my box... hehe

Usually I spend main time finding out proper random value for branches
distribution (value Randomness on Branch panel). The rest doesn't need
so much time.

I understand that there is a lack of tutorial. I'll try to make it whenever
I have time. I'm also planning to make pictorial tips instead of text tips
(which were just taken from TOMTREE help file). I think it will help
a lot in understanding TOMTREE/POV-Tree functionality.

Next release will have three more examples - pine, oak and some bushes.
And I'll stop there with examples :)

Yeh, summertime... it's better to enjoy real trees at this time :)

In an almost related comment, I was trying to create realistic grass last
winter, and I messed with the textures forever until they got quite dark,
and less green, because that was the way I remembered grass actually
looking.  Now that summer is here, I find that grass doesn't look quite like
I had remembered.  It's greener.

Just like they say, "The grass is always greener..."  Sorry, I couldn't
resist the pun... ;-)

Done. I have also updated the page to include the new

Any idea when these examples might become available (LOTS of pine trees and
oak trees in my area)? Also, have you considered upgrading the program to
take advantage of the mesh2 feature of the newer version of POV-Ray? Again,
keep up the great work!

I don't know exactly. For next release I'm going to implement
support for blossom. That will need implementation of blossom
generator and the same stuff for mesh blossom which I did for
leaves in last release - predefined mesh flowers and custom
mesh blossom. That will take some time.

What's the advantage of mesh2? I cannot get it from the doc.
Does it have more compact syntax?

You shouldn't put your email-adress up on display like

An email-crawler wouldn't get that last bit of information.

Short Answer: Yes, the mesh2 has a signifigantly more compact syntax.

Long Answer:

The basic advantage of the mesh2 syntax is that the properties (including
location, pigiment, normal, finish, etc.) of any common vertices of several
triangles need only be specified once, instead of being re-specified for
each triangle. For example, if you had six triangles intersecting at the
same point, all properties of that point (again, location, pigment, normal,
finish, etc.) would only need to be specified once, instead of six times.
As a result, the file size would be (in this example) one sixth of the
size, and parse six times faster, all while taking up less system memory! A
signifigant increase! The file space, parsing time, and memory saved using
the mesh2 increases dramatically when even more triangles share common
points, and tend to work even better on closed objects as every triangle
has all vertices in common with several other triangles.

The parse time of the mesh2 syntax is also slightly faster than that of the
standard mesh, due to the fact that the mesh2 syntax resembles very closely
the internal 'mechanics' that POV-Ray uses for meshes; as such, less time
is required to convert the format.

A couple of other advantages of the mesh2 syntax are the ability to easily
implement u-v mapping, as well as creating triangles with a different color
at each vertex. Additionally, the mesh2 syntax allows for textures to be
specified within the mesh2 structure, rather than requiring them to be
pre-defined as in the original mesh syntax. These last advantages may not
be very helpful to you since, as far as I can tell, they aren't currently
used in your meshes now anyway. Who knows--maybe you'll find a way to use
them in future releases!



This was probably a little bit more of a response than you had bargained
for, but I figured I may as well put it all out there! Again, keep up the
great work!

Nick's answer is quite exhaustive, but there's also a more hidden advantage
to mesh2 : its syntax is close to the obj format (lists of vertices,
normals, uvs). If you can output to mesh2 you can figure out how to output
to OBJ (I think Rune did something like this). And OBJ, unlike mesh2 which
is POV-only, is a popular 3d format which means that your app could export
to any 3d application out there from Bryce to Maya.

Thanks for the answer. First search result for mesh2 on POV-Ray site
was not so helpful as your answer :) Though then I found more
detailed description.

 From implementation point of view mesh2 doesn't
look so obvious. The program should keep in memory several
arrays: vertices, faces etc. For such data intensive program it's
impossible. So another solution could be several passes through the
model - one pass for vertices, one for faces etc. It will take
more time but it won't need so much memory as first approach. And
another solution could be to create several temporary files during
one pass - one file for vertices one for faces and so on. And then
just append those files.

Anyway I'll try to do that in one of the future releases.

Gena.

Tom Aust (who is the author of the tree algorithm used in POV-Tree)
asked me some time ago if it's possible to use the program for
commercial purposes. I think commercial purposes in this case means
ability to export trees in "commercial" formats - DXF, OBJ etc.
Right now it's impossible (at least directly). I believe it should
not be a problem to implement export in one of those "commercial"
formats. I just feel some kind of obligations... :)

It could be an interesting experiment... and a little dangerous! Right now I
don't think that there are so many free tree generators (the one build in
Bryce isn't very good) for popular 3D apps (except POV-Ray) and the Tomtrees
can really be impressive. If you develop a "commercial" export, this is
likely to become a hit with all the good and bad that comes with this sort
of situation...

Dear Gena,

if you remember, I asked you this question because I don't want that 
commercial programs (3DS MAX, MAYA, ...) could use Tomtree - at least not 
for free !
This was and is an opportunity I would reserve for myself or perhaps for 
teamwork.

So, I watch and watched such discussions partly(!) with unease.

Nevertheless, I feel that I should overcome my laziness in writing for a 
common work.


But, please don't kidnap my Baby !


paranoid greetings
