En fait, si, il est tard, mais j'ai envie de raconter des
|
||||
conneries.
|
||||
Un bloub est une entité mathématique qui vit
|
||||
dans un espace cartésien abstrait, bien que normé.
|
||||
Il peut aussi être borné, soit en mode "boite", soit
|
||||
en mode "tore". La notion de champ de gravité est
|
||||
ignoré, parce qu'un bloub se moque d'avoir une masse.
|
||||
Par contre les bloubs peuvent interagir entre eux
|
||||
de divers manières : rebond (genre billard), échange
|
||||
de données, fusion volumique...
|
||||
|
||||
## Technique
|
||||
|
||||
Voici la version du _Sat 19 Feb 2022 12:37:42 AM CET_
|
||||
Un bloub est caractérisé par un certain nombre de valeurs,
|
||||
rangées dans une structure de donnée.
|
||||
Ces valeurs représentent des choses comme la position,
|
||||
la taille, l'age et la couleur d'un bloub.
|
||||
|
||||
En voici la version Fortran du _Fri Jan 26 00:58:37 UTC 2024_,
|
||||
c'est à dire presque (mais pas que) complètement différente
|
||||
de l'état actuel ou possible du logiciel. Il faut noter que
|
||||
certains champs ne sont pas encore utilisés.
|
||||
|
||||
```
|
||||
type t_bloubs
|
||||
character(8) :: nick
|
||||
logical :: alive
|
||||
integer :: state
|
||||
integer :: num ! ???
|
||||
real :: px, py, pz
|
||||
real :: vx, vy, vz
|
||||
real :: radius
|
||||
integer :: age
|
||||
real :: density
|
||||
integer :: age, agemax
|
||||
integer :: red, green, blue
|
||||
end type t_bloubs
|
||||
```
|
||||
|
||||
Certains champs sont assez explicites, comme le nick, la position
|
||||
dans l'espace, le rayon (pour nous, un bloub est
|
||||
une entité abstraite assimilable à une bubulle)
|
||||
ou la vitesse sur les trois axes.
|
||||
D'autres, comme `alive`, sont
|
||||
plus délicates à expliquer, sauf si l'on considère que les
|
||||
bloubs sont zombifiables.
|
||||
Certains champs sont assez explicites, comme le *nick*,
|
||||
la position dans l'espace, le rayon (pour nous, un bloub est
|
||||
une entité abstraite assimilable à une bubulle) ou la vitesse
|
||||
sur les trois directions de l'espace bloubeux.
|
||||
D'autres, comme `alive`, sont plus délicates à expliquer,
|
||||
sauf si l'on considère que les bloubs sont zombifiables.
|
||||
|
||||
D'autres, comme l'age, sont bien plus sujettes à de diverses
|
||||
D'autres, comme age et agemax, sont bien plus sujettes à de diverses
|
||||
interprétations. doit-on incrémenter l'age à chaque tick d'horloge
|
||||
ou à chaque évènement discret ? Et à quel age un bloub devient-il
|
||||
trop vieux, à quel age va-t-il mourir ?
|
||||
|
||||
## La fusion des blobs
|
||||
|
||||
Quand deux bloubs se rencontrent (en première approche, cela veut
|
||||
dire que leurs surfaces se recoupent) il y a bien entendu quelque
|
||||
chose qui se déclenche. En général, c'est la fusion des deux
|
||||
bloubs. Mais une fusion de bloubs, c'est quoi ?
|
||||
|
||||
Je pense qu'il y a une infinité de possibilités, je vais me contenter
|
||||
d'expliquer la démarche que j'ai suivie.
|
||||
Tout d'abord, pour la fusion de certains paramètres, comme la position
|
||||
ou la vitesse, on va faire simple : une moyenne sans pondération.
|
||||
Précis et efficace.
|
||||
|
||||
Pour d'autres (le nick & le num) je n'ai pas d'idée bien précise,
|
||||
il y a peut-être la notion de « nick dominant » à définir.
|
||||
Par contre, c'est peut-être sur les valeurs 'corporelles' :
|
||||
taille, densité, age et couleur qu'il y a des choses à faire.
|
||||
|
||||
* Taille : c'est le `radius` d'une sphere -> somme des volumes
|
||||
* Densité : cette valeur n'est actuellement pas gérée
|
||||
* Age : (somme des deux ages) * coefficient
|
||||
* Agemax : (maximum des deux agemaxs) - forfait
|
||||
* Couleurs : un système de mutation selon critères ?
|
||||
|
||||
Il ne reste qu'à coder tout ça...
|
||||
|
||||
## Analyse de population
|
||||
|
||||
Nous avons des moyens assez simple d'enregistrer l'état complet
|
||||
de la population de bloubs à chaque itération.
|
||||
La meilleure preuve étant les vidéos publiés dans les peertubes.
|
||||
Mais nous devrions plus nous pencher sur les aspects statistiques,
|
||||
comme la démographie, l'état de santé, la pyramide des ages...
|
||||
|
||||
Les traitements simples peuvent faire appel à Awk et Gnuplot.
|
||||
Pour les visions plus avancées, un logiciel spécialisé sera
|
||||
le bienvenu, et **R** est un bon candidat potentiel.
|
||||
On peut aussi envisager la pureté du code Fortran,
|
||||
couplé avec un *toolkit* graphique comme XXX.
|
||||
|
||||
Il ne reste qu'à coder tout ça...
|
||||
|
||||
## Et pour la suite ?
|
||||
|
||||
Au fil du temps, le bloub évolue et se complexifie.
|
||||
La prochaine itération sera dotée d'un attribut de couleur et
|
||||
d'amusantes fonctions pour mixer ces couleurs si deux bloubs
|
||||
se trouvent à fusionner.
|
||||
On peut aussi envisager de les munir d'un spin non entier
|
||||
dans le but assumé d'augmenter la complexité des rencontres
|
||||
interbloubs.

### wavmetrics
|
||||
|
||||
This module try to make some computations on *stereo* buffers.
|
||||
|
||||
This is just a [WIP](./wavmetrics.f90), see [twavm](./twavm.f90) for a no-use case.
|
||||
|
||||
### spitpgm
|
||||
|
||||
Write gray level 2d buffer (aka picture) to disk in the NetPNM format.
|
||||
|
||||
## pixrgb
|
||||
### pixrgb
|
||||
|
||||
Write 8 bits RGB pictures to PNM format.
|
||||
Write 8 bits or 16 bits RGB pictures to PNM format.
|
||||
The width of the picture MUST be a multiple of 4 !
|
||||
|
||||
## trials
|
||||
### trials
|
||||
|
||||
Experimental WIPs from hell.
|
||||
|
||||
### dummy
|
||||
|
||||
A "do nothing" useless module.
|
||||
But you cas use it to fool an optimizing compiler,
|
||||
or have a sane place to put a breakpoint with gdb
