Problème de modélisation sur Delphi

Bonjour,
je rencontre un petit problème sur Delphi: j'ai modélisé un pont et celui ci doit se lever. Or, j'arrive à faire bouger les trois lignes qui représentent le pont mais pas le polygone qui représente l’extrémité du pont ,et dont le mouvement doit être synchronisé avec celui-ci (question de réalisme). Auriez vous des idées à me proposer? J'ai joint une image du problème ainsi que les lignes de code. Pièce jointe 147300

Code:

Petite question :
Pourquoi ne pas utiliser des bibliothèques (comme OpenGL) dont c'est le rôle (de faire de la 3D), plutôt que de réinventer la roue ?
(Je suis d'accord que ça peut avoir aussi un intérêt à faire les choses par soi-même)

euh...tu calcules déjà 3 des points formants l'extrémité du pond...il ne reste qu'à calculer le quatrième et dessiner le polygone

Code:

---

1 2 3 4 5 6 7 8 9 10 11

var p: array[0..3] of TPoint; begin ... p[0].x := round(c0+r3*-cos(t)); p[0].y := ... p[1].x := ...   polygon(p); end;

Bonjour,
Merci pour la réponse :) ,cependant après avoir intégré les lignes de code, et crée le polygone, cela ne marche toujours pas :( . Voici les lignes de code (les lignes que j'ai intégrées selon vos conseils commencent à partir de la ligne 175).

ce doit être une blague, c'est pour caméra cachée belge c'est ça ? ils sont trop fort pour faire des gags les belges :)

Non, non, je vous assure, ce n'est pas une blague :) J'ai beau avoir integré votre code et le polygone ne bouge toujours pas d'un centimètre... (cela peut aussi etre du au fait que je sois débutant sur Delphi...)

Si p[0] à p[3] sont les points de l'extrémité du pont alors le polygone de l'extremité du pont c'est polygon([p[0], p[1], p[2], p[3]]) et non le polygone des constantes en rouge.
En plus il manque le calcul de p[3].

ou plus simplement Polygon(p) comme donné dans mon code :)

C'est surtout ces 100 radians qui piquent les yeux 8-)
