I thought it was better to give as much information as

Done. I have also updated the page to include the new
source (1.1) and to remove the oldest Povtree version
(1.0b)

Thank you!
BTW, I sent you a couple e-mails. Is your e-mail
address still valid?

I have seen the one you have send me today (I just
have arrived from work a while ago and have entered
1st in the newsgroups). I will answer you as I finish
this post.

Maybe I deleted one of your posts by error.

An awesome upgrade to an already powerful program! Keep up the great work!

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
that, not on open newsgroups like this one. Since
Google is able to crawl open newsgroups, others might
do so too. There are crawlers out there designed to
hunt for email-adresses. I advise to do as I do on
my website: just plain-text for your email.

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... :)
