 # HexaCone
 
-Projet POVray de l'hiver 2024/2025 : un objet hexaconal,7
-prenant en compte les divergences d'opinion. Le concept
-sera amélioré au fil du temps, et vous pourrez lire son
-évolution dans
-[Mastodon](https://mastodon.tetaneutral.net/@tth) #hexacone.
+Un projet POVray né pendant l'hiver 2024/2025, au fin fond du Gers :
+un objet **hexaconal**
+prenant en compte les divergences d'opinion et les fluctuations
+de la temprérature du salon.
+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`.
+
+## Prérequis
+
+Avant toute chose, il faut avoir installé les logiciels
+suivants : bash, awk, gnuplot, imagemagick, et, bien
+entendu, [povray](https://povray.org/).
+
+## Utilisation
+
+Il y a deux choses que l'on peut tracer :
+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 :
+
+
+```
+    frames/
+    ├── essai
+    ├── orbite
+    ├── passage
+    ├── escadrille
+    ├── scene
+    ├── Spool
+    └── topview
+```
+et de l'autre coté `./WS/` pour ranger les fichiers de travail.
+
+## Contact
+
+* La [mailing-list du tetalab](https://lists.tetalab.org/postorius/lists/tetalab.tetalab.org/) ;
+* IRC canal `#tetalab` sur le
+réseau de [Libera](https://libera.chat/).
