I am astonished to see the thread starting with From: Varoquaux <varoquau@cl...> Povray terminal output 2005-01-16 06:02 . # I am sorry I can not append my mail to the thread. I just submitted. > This is a bit a crazy idea, but I was wondering if it would be possible to > have a povray terminal output for gnuplot, a bit like the latex terminal. I and one of my students, Miyata, are currently working on the POV-Ray and VRML terminal of gnuplot. For several months we have explored and modified the source files under src/, and it is beginning to work now. It is just a alpha-version and not so neatly written. Maybe in several weeks we can provide our patch file to add these two terminals here at this ML. Followings are the sample images created by povray (originally TGA formatted) with our output files : (only 'plotting with points' is possible now) http://alt.cc.kumamoto-u.ac.jp/tmp/tt1.jpg http://alt.cc.kumamoto-u.ac.jp/tmp/tt2.jpg http://alt.cc.kumamoto-u.ac.jp/tmp/tt3.jpg Output files are like this : http://alt.cc.kumamoto-u.ac.jp/tmp/tt1.pov -- KITA Toshihiro http://t-kita.net/ PGP-Key: http://t-kita.net/pubkey.asc fingerprint : CBFF 6A61 5990 10F5 B4B6 D2E8 279A 7063 CF8B 6339 |

Just a few comments:
- Your povray file is buggy. You are using #macro defines and state that
you have version 3.0. Please use
#version 3.1
- Have you thought of adding spheres to the end of cylinders? This would
make the output much nicer.
Please try it with my changes:

I am very glad to have your comments.

Oh, I was always testing files with povray 3.1g. (included in the
Linux distribution called Vine commonly used in Japan)
I just found the latest version of POV-Ray is 3.6.1.
I guess it would be better to write
#version 3.6;
And moreover, warnings like
File: tt1.pov Line: 58
Parse Warning: Degenerate CSG bounding box (not used!).
...
still remain.
From now on I will use povray 3.6.1 for testing.

That is a nice suggestion.
We will change the program according to your suggestion.
Any questions and comments are welcomed. > all

This is very good new. I was going to give it a try, but I am definitely not a good coder and it would have been quite hard for me, especially since I have very little time to spend on this. If I can be of any help don't hesitate, but I must warn you, I am not an IT professional therefore my ability to read or write code is quite low, and I have started using povray only two month ago. However this is a project I find very exiting, both for my own use, and for gnuplot's future and I am more than willing to help. Gaël |

That is not so. That e-mail I sent is the first announcement of our = development. You can see what we previously developed at http://t-kita.net/webplot/ http://t-kita.net/som/ but, they are not directly related to gnuplot. # Actually the POV-Ray terminal codes began to work only one or two # weeks before. > > I and one of my students, Miyata, are currently working on the > > POV-Ray and VRML terminal of gnuplot. > = > This is very good new.

Honestly, we are not so good at coding either. Our codes are simply made after trials and errors, so I am afraid = gnuplot developers will be disappointed at our dirty codes. > If I can be of any help don't hesitate, but I must warn you, I am = not an IT > professional therefore my ability to read or write code is quite low,= and I have > started using povray only two month ago.

Unlike other popular GUI-based plotting tools, gnuplot can be easily dr= iven by CUI-based commands and scripts. That is why I love to use gnuplot and I want to add virtual-reality terminals to it. Anyway, we would like to release the patch file as soon as possible. # to avoid excessive expectations. :-) -- = KITA Toshihiro http://t-kita.net/ PGP-Key: http://t-kita.net/pubkey.asc fingerprint : CBFF 6A61 5990 10F5 B4B6 D2E8 279A 7063 CF8B 6339 |

Anything that works is a starting point, and therefore a great progress, I find. It gives a basis to start building on. I am very much looking forward to see your work. Could you please Cc. me for issues concerning the povray terminal, as I am not a subscirber of the mailing list. Good luck with your work, Gaël |
