# TP Interaction
|
||||
|
||||
Ce TP a pour but de vous faire coder des interactions avec un modèle 3D. Pour
|
||||
cela, vous implémenterez en Javascript des interactions avec la souris et avec
|
||||
les touches du clavier qui permettent de changer de point de vue, c'est à dire,
|
||||
de mettre à jour la position et l'orientation de la caméra (Partie 1), et
|
||||
ensuite d'enregistrer de tels points de vues pour permettre une navigation plus
|
||||
haut niveau (Partie 2).
|
||||
|
||||
Ce TP sera fait pendant les séances consacrées (un TP jeudi 9, un TP jeudi 16).
|
||||
|
||||
### Cloner le repository
|
||||
|
||||
```
|
||||
git clone https://gitea.tforgione.fr/tforgione/tp-interaction
|
||||
```
|
||||
|
||||
### Lancer le server
|
||||
|
||||
```
|
||||
python -m SimpleHTTPServer
|
||||
```
|
||||
|
||||
Vous pouvez ensuite aller sur la page [localhost:8000](http://localhost:8000)
|
||||
pour lancer l'interface. Pour voir la console vous pouvez cliquer sur `F12`,
|
||||
ce qui vous permettra de debugger plus facilement.
|
||||
|
||||
### Sujet
|
||||
|
||||
#### Partie 1 : interaction clavier / souris
|
||||
|
||||
L'objectif de cette premiere partie est d'implémenter les interactions type
|
||||
*free fly camera*. Nous vous proposons de mettre à jour les interactions avec
|
||||
la souris pour tourner la caméra et avec le clavier pour la deplacer.
|
||||
|
||||
L'utilisateur peut appuyer sur les flèches du clavier pour déplacer la caméra :
|
||||
- flèche en haut (ou touche z) pour avancer
|
||||
- flèche du bas (ou touche s) pour reculer
|
||||
- flèche de gauche (ou touche q) pour se translater vers la gauche
|
||||
- flèche de droite (ou touche d) pour se translater vers la droite
|
||||
|
||||
Ces directions seront définies à partir de l'orientation de la caméra, donnée
|
||||
par 2 angles `theta` et `delta`.
|
||||
|
||||
|
||||
|
||||
Vous pouvez trouver des exemples de coordonnées sphériques sur
|
||||
[wikipedia](https://fr.wikipedia.org/wiki/Coordonn%C3%A9es_sph%C3%A9riques).
|
||||
|
||||
**Attention** : dans THREE.js, l'axe des y est celui qui va vers le haut.
|
||||
|
||||
Pour cette partie, vous aurez besoin de compléter les *TODO Part 1* du fichier
|
||||
`js/main.js`.
|
||||
|
||||
#### Partie 2 : interaction via point de vue
|
||||
|
||||
L'objectif de cette deuxième partie est d'utiliser les points de vue
|
||||
enregistrés pour faciliter l'interaction. Pour commencer, vous pouvez
|
||||
décommenter les lignes 236 à 239 du fichier `js/main.js` pour faire apparaitre
|
||||
un point de vue. Vous devez ensuite compléter les *TODO Part 2* pour permettre
|
||||
à un utilisateur de cliquer sur un point de vue pour s'y déplacer.
|
||||
|
||||
### Les vecteurs dans THREE.js
|
||||
|
||||
Ce TP utilise le moteur de rendu THREE.js. Puisque javascript ne permet pas la
|
||||
surcharge d'opérateurs, il est impossible d'écrire `x + y` quand `x` et `y`
|
||||
sont des vecteurs de THREE.js. Ansi, THREE.js définit des méthodes pour
|
||||
effectuer ces opérations :
|
||||
|
||||
| Avec opérateurs | En THREE.js |
|
||||
|:----:|:---:|
|
||||
| `a += b` | `a.add(b)` |
|
||||
| `a -= b` | `a.sub(b)` |
|
||||
| `a *= l` | `a.multiplyScalar(l)` |
|
||||
| `a = b` | `a.copy(b)` |
|
||||
| `a + b` | `a.clone().add(b)` |
|
||||
| `a = b + c` | `a.copy(b.clone().add(c))` |
|
||||
| ... | ... |
