Hi,

I just brought Texture Library version 4.0 online. If you know version 
3.0 on texlib.povray.org you may be interested in the new one as well - 
http://www.rene-schwietzke.de/povray/texlib/

Version 4.0 features:
- a complete new design, lean and fast
- every texture is shown in 8 demo scenes
- textures are grouped by categories and colors
- textures can be browsed by name or category
- textures can be listed by name, include file, color, category, author

The current version features contains only textures from textures.inc 
but the library will be enhanced step by step with more textures (just 
give my computer some time to render the demo scenes).

Any comment is appreciated. Feel free to contact me.

Enjoy Texlib 4.0,
Rene

P.S. As soon as Texlib 4.0 will have reached a mature state, it will be 
mirrored on texlib.povray.org.

Thank you. Do you miss anything? Texture information, and certain kind 
of demo scene, or ways to search for a texture?

  It works for me. Others may have suggestions for improvement. It loads
fast (I'm on cable modem) and the layout is very intuitive, IMO. It also
looks nice!

Looks like a lot of work - a few remarks:

- it is quite unusable in Netscape 4.x although i can't find a good reason
why it has to be.  
- an option for downloading the whole library would be great.
- the lot of different sample renders look quite nice but some are a bit
unnecessary (for example the 2d rotation/scaling tests).  The preview
should IMO contain a sphere object so you can see at the first glance what
kind of finish and normal it has (highlights, variable reflection, ...)
The 'shapes' render contains various shapes but lacks a rough surface
(heightfield or isosurface for example).  
- the water texture should get an interior with ior to look realistic.  
- maybe it would be a good idea to add a 'purpose specific render' - a sky
sphere for sky textures, a plane with a sky for water textures, ...

Hi Chris,

thank you for the comments, see me answers below:

> - it is quite unusable in Netscape 4.x although i can't find a good reason
> why it has to be.
It is HTML 4.01 Strict and CSS 1.0/2.0. It was my intention to produce clean
and lean HTML code, there are enough good browsers for all platforms, so I
do not want to support the old Netscape stuff anymore. Mozilla 1.2, Netscape
6 and 7, IE 5,5.5,6.0 are fine.

> - an option for downloading the whole library would be great.
Do you mean an offline version?

Why is the 2d scaling and rotation not necessary? Do you know better scenes
instead?

> kind of finish and normal it has (highlights, variable reflection, ...)
The previews are quite small images and therefore the space might not be
enough to show this already in the preview.
I will give it a try, maybe I find a scene. It takes time to re-render the
library, so please be patient.  I am going to post a demo image in the
binaries.images group.

On its way...thanks.

I plan an additional scene depending on special characteristics and
categories,such as Water, Sky, Glass. A demo is going to be posted in the
p.b.images group soon.

Thank you and stay tuned, the library will grow and change a lot,
Rene

Well, it is of course up to you how to design the page but i meant i did
not recognize any elements in your page that seem impossible to be created
in a way not messing up the page in NS 4.x.  Of ocurse not everything will
be visible in NS 4.x as in newer browsers but it could be usable.

Yes.

I meant totally dripping it.  The first line of 3D spheres in those
pictures already gives all information - the other two lines are quite
redundant.

I think with the size of preview it would be just fine.

What about HtmlHelp produced from time to time?

btw: at the "Contribution" section I can't find specification of the targeted
POV-Ray. Do you accept only 3.5 ? 3.1 ? MegaPOV 0.7 ? 1.0 ?

Texlib uses CSS and does not store any design information in the html code.
Because of the lack of css support and a lot of defects in Netscape 4.7, it
would be necessary to create the pages differently (more tables, more design
info in the code). It also does not implement the HTML 4.0 standard very
well.

Please accept my apologies for not supporting Netscape 4. Any reasons for
using it?

The library might be a little bit to huge for a help file. It is currenlty
40MB and grows rapidly.

Mmm...good question...the best would be to limit the support to offical
supported features or at maximum MegaPOV features. This means 3.5 and
MegaPOV 1.0. POV3.1 textures are fine too, they should work with 3.5 without
or at least after minor modifications.

We will see what kind of textures arrive. Let's postpone the decision a
little bit ;-)

You did not understand me, i didn't say "don't use any of those new
features not supported by old browsers".  I just meant it should be
possible to avoid those features messing up the result in NS 4.x.  It does
not have to look great, it only should be visible at all.

> Please accept my apologies for not supporting Netscape 4. Any reasons for

Because it still is the standard browser on a lot of machines (all public
terminals at university here for example).

I will investigate this problem but cannot promise a solution. It is
definitly related to CSS. If you disable CSS in the Preferences, it is
readable at least - that's one of the features I have tested --> using
Texlib without CSS.

The copyright issue makes me afraid to use your site.

Do we have a community for those who hope to profit from their contribution
to a pile of software,  or a community for those who want to retain the
spirit of freeware?  Am I being too anal in seeing red in the fussiness with
copyrights?

Are the copyrights essentially:
i)  defensive: to prevent a third party from claiming exclusive rights and
thus preventing these authors from making a profit on their own work?
--or--
ii) offensive:  Use is free unless you make commerical use of my pigment.
In this case notify me and we'll discuss.  These folks stand on the shoulder
of giants in using povray but then want a dime for the lift they give the
next bloke.


I have no valid hope of ever making money on this hobby, but I can dream,
and if I create something I don't want to have to fret over what has this
copyright tripwire on it.  If I texture a trashcan in a corner of a scene,
and five years from now reuse the code in a TV commercial, will I get sued?

I would much rather  just use ****freeware****   and contribute to the
freeware community as I am able.

The problem is *much* worse than that. I have downloaded your entire library
with GNU wget (34,175,505 bytes total), and my offline version of your
library looks like complete crap in IE6 (and yes, I do have good reasons of
using both wget and IE6).

Other than that, your library is great and seems to be quite useful... many
thanks for the hard work. The only request: if only possible, please try to
make its internal (page) design a bit simpler; it seems like many people
would benefit from that.

Thanks,
Vadim.

If you download the entire website you should be able to browse it offline
because that's the way I develop the library, offline. Texlib currently uses
the CSS file of the main website because I have not decoupled the library
from the rest of the website yet, but it will be my next step because
everyone asks for a downloadable version.

I will do my best to fix all these issues during this week and upload a new
version at the weekend.

Thanks for the comments,
Rene

Hi Greg,

you are right. Recently I had trouble with a lawyer because of my old
website, therefore I try to be as careful as possible. I might have
exaggerated it. I am sorry.

How about this:
1. I will only include textures in the library which are freely useable for
any purpose except reselling the texture itself.
2. Modification are allowed and the derived texture is also freely usable
and distributable if the inital author is credited - except reselling it.
3. Reselling a texture (not(!) the images made with it) is only permitted if
the author has been asked before - except for the original textures of
POV-Ray of course.

Does this sound better?

Thanks,
Rene

No need to be sorry. It may well be the case that some people willing to
provide textures would ask for this possibility. Actually there's a growing
trend for free content providers to put extra requirements about their
stuff. The "non-commercial use" clause is the most common, but some really
weird demands have appeared lately, like people who do not want their free
prop being used in "violent" or "satanic" scenes... There seems to be no
limit there. Next time I release props, I'll make sure to put a clause in
the license asking people to do the chicken dance first and send the video
to me :-)
On one hand, I don't quite understand this sort of demands (not to mention
that they are hardly enforceable). On the other hand, people are obviously
free to write their own EULA and put in whatever they want. But do we want
to encourage that ?
In regards to POV-Ray related material, I think that the rule of thumb
should be that the EULA for a freebie should not be harsher than POV-Ray's
own and prohibit only potential abuses (like reselling or stealing/hiding
the copyright), so the modification you propose seems right to me.

Do you know that there is a

You can just hide those parts of the style sheet, NN4 is having problems 
with, from it.

Hi,

Currently I am rendering a new version of the library. It takes some time
(500MHz Celeron), I utilized additional machines, but due to my own
stupidity these results are worthless...so I will try it again.

I fixed several things and will publish the update this week (2003-week 03):

- Texture Library can be used standalone now (download version)
- Scaling and Rotation tests were merged into one scene
- Shapes test includes an isosurface now
- Copyright was simplified
- Image brightness changes

Bye,
Rene
