 # HexaCone
 
-Projet POVray de l'hiver 2024/2025 : un objet hexaconal,7
+Un projet POVray né pendant l'hiver 2024/2025, au fin fond du Gers :
-prenant en compte les divergences d'opinion. Le concept
+un objet **hexaconal**
-sera amélioré au fil du temps, et vous pourrez lire son
+prenant en compte les divergences d'opinion et les fluctuations
-évolution dans
+de la température du salon.
-[Mastodon](https://mastodon.tetaneutral.net/@tth) #hexacone.
+Le concept initial, assez inprécis, sera amélioré au fil du temps,
+et vous pouvez
+suivre son évolution par l'intermédiaire de
+[Mastodon](https://mastodon.tetaneutral.net/@tth)
+avec le *croisimot* `#hexacone`.
+Quelques images sont disponibles sur mon serveur de
+[cuisine](http://maison.tth.netlib.re/pov/hexacone.html),
+avec même des liens vers les vidz.
+
+## Prérequis
+
+Avant toute chose, il faut avoir installé les logiciels
+suivants : bash, awk, gnuplot, imagemagick, ffmpeg, et bien
+entendu, [povray](https://povray.org/).
+Une bonne maitrise des scripts shell (en Bash) sera un plus.
+
+## Utilisation
+
+Il y a deux choses que l'on peut raytracer :
+les images fixes, qui sont traitées
+par un classique [`Makefile`](./Makefile) et les séquences animées
+produites par un [script shell](./mkloop.sh).
+
+Avant toute chose, vous devrez vérifier la présence de plusieurs
+répertoires :
+
+D'un coté `./frames/<name>` pour stocker les images calculées
+de chaque séquence et
+./frames/Spool` pour l'assemblage de la vidéo intégrale :
+
+```
+frames/
+      ├── essai
+      ├── orbite
+      ├── passage
+      ├── escadrille
+      ├── scene
+      ├── Spool
+      └── topview
+```
+et de l'autre coté `./WS/` pour ranger les
+[fichiers de travail](./WS/README.md).
+
+Ensuite, il faut assembler toutes ces images calculées en une vidéo
+de qualité (ce que fait je très empiriquement). Tout d'abord, on encode
+(avec ce [script](./tools/encode.sh)) chaque séquence individuelle
+pour les mettre dans le grand Ternet mondial à partir de mon
+[ADSL](http://maison.tth.netlib.re/pov/hexacone.html) de campagne.
+Ensuite, un autre [script](./tools/linkfarmer.sh) assemble toute
+les séquences dans le produit
+[final](http://maison.tth.netlib.re/v/hc/full.mp4), en ajoutant
+générique et inter-titres.
+
+À vous de jouer maintenant : *« Fork & Enjoy »*
+
+## Contact
+
+* La [mailing-list du tetalab](https://lists.tetalab.org/postorius/lists/tetalab.tetalab.org/) ;
+* Par IRC, canal `#tetalab` ou `#povray` sur le réseau de [Libera](https://libera.chat/).
+* Dans [Mastodon](https://mastodon.tetaneutral.net/@tth) et [Peertube](https://tube.interhacker.space/c/tth_channel/videos)
+
+## La suite
+
+Il reste bien des choses à faire : [TODO](TODO.md) list.

+- Songer à un cadriciel pour la piste son.
+- Trouver un compositeur et les musiciens.
+- Étudier à fond la documentation de `sox`

+
+## Make a sequence
+
+Un argument pour construire la séquence entière ou deux pour démarrer au
+milieu, c'est parfois pratique quand le disjoncteur fait un *beu-beu* en
+plein milieu. Exemples :
+
+```
+  $ tools/mkloop.sh survol
+  $ tools/mkloop.sh survol 133
+```
+
+Et pour générer plusieurs séquences dans la foulée, avec les
+post-processings (ega-mp4 et ega-gif89a) en même temps,
+vous avez le script [Mk Sex](mkseqs.sh) à votre service.
+
+Mkloop ajoute le nom de la séquence, le numéro de trame et le temps de
+rendu au fichier `log/mp4.timing` permettant ainsi la création de
+graphiques aussi jolis qu'inutiles.
+
+## Linkfarming
+
+C'est le directeur de la production, le grand
+[script](./linkfarmer.sh)
+d'assemblage des séquences avec générique et intertitres.
+Hélas, il n'est pas encore configurable. Mais c'est
+en projet pour juin 2026 ?
+
+## Encoding
+
+Le [script](./encode.sh) n'est qu'un wrapper autour de
+la fonction `ff_encodage()` de la lib des tools :
+[fonctions.sh](fonctions.sh). Par défaut, il encode
+la séquence *essai*.
+Le fichier de sortie s'appelle *wip.mp4* dans tous les cas.
+
+## Plot the timing
+
+On peut visualiser le temps de calcul d'une séquence avec la
+commande [plot-timing.sh](./plot-timing.sh) qui génère un fichier
+PNG. C'est un script basé sur *Awk* et *Gnuplot*.
+Ces graphiques sont utilisés comme fond pour les
+intertitres.
+
+```
+$ tools/plot-timing.sh essai && d timing.png
+```
+
+Cette commande utilise le fichier `log/mp4.timing`, lequel est généré
+par le script de création de séquence vu plus haut.
+
+
