OPENGL HELP !!!Résolu/Fermé

Question

D'abord ! BONJOUR A TOUS !!
Bon, juste une petite question :
Je fait mes début en opengl, j'ai donc programmé une tite appli.
Jusque là, pas de problème, c'est juste un cube avec une sphere à l'intérieur, que l'on peut faire tourner plus ou moins vite en appuyant sur es touche up , down.
Chez moi, ça tourne niquel, par contre, j'embarque l'appli sur un autre PC, là aussi ça tourne, mais plus lentement ! Il faut appuyer 2 heures sur la touche up pour que ça commence à bien tourner, alors que chez moi, il faut un appui de une seconde sur cette même touche pour obtenir le même résultat !
Je me suis dit, pb de proc ou de carte vidéo.
Pour tester, je prend une démo programmé en delphi, je la lance chez moi, no problème, je la lance sur l'autre pc, no problème non plus ! Je ne comprend plus rien !
Voici le code de mon appli :

J'ai trouvé la solution !!!
En fait, il suffit juste d'activer le vsync sur le premier pc, cela ralenti donc la bécanne, ensuite, recoder l'application pour quelle tourne à bonne vitesse, et le tour est joué.

florenth · Answer

Heu tu sais qu'avec GLScene(dans delphi evidemment), je fais la même chose en 2 min et en tapant 5 lignes de code ???

Cela laisse songer.

Concernant ton problème, cela vient sûrement du fait que la carte graphique de l'autre ordinateur supporte moins OpenGL.
Car je parie que l'autre application que tu as testée utilisait DirectX ??

Et concernant ce probleme, il n'y a pas trop de solutions a part se mettre a DirectX a l'aide de DelphiX !!! Mais après l'OpenGL, c'est dur de s'y mettre

Bonne chance et n'oublie pas GLScene si tu continues dans l'OpenGL (par contre tu alourdis un peu ton Exe, toi qui a l'air très penché sur ce probleme).

Merci pour la réponse ! ;)

GLScene, j'ai déjà testé, mais j'ai envie de progresser en prog, j'aime pas trop utiliser des trucs tout fait, j'ai pas envie que ça sois delphi qui m'initialise mes fenetre par exemple, j'aime bien le faire moi même.

Contrairement à ce que tu pense, l'autre application est 100% Delphi, d'ailleur, une grosse partie du code vient de cette application !

Concernant directX, j'aime pas trop, car tourne que sur windows !!

j'aime pas trop utiliser des trucs tout fait

Le copier-coller que tu as fait dans ton code, c'est bien pareil ...


j'ai pas envie que ça sois delphi qui m'initialise mes fenetre par exemple, j'aime bien le faire moi même

Delphi est un outil RAD (Rapid Application Developpement). Cela veut dire que c'est fait pour se concentrer sur le plus important : Le code des evenements.

C'est comme un DJ : ce n'est pas le temps qe l'on met pour caler et temporiser le disque qui fait la difference : c'est simplement la fait de mieux choisir ses chansons et d'organiser son Mix ....


Contrairement à ce que tu pense, l'autre application est 100% Delphi, d'ailleur, une grosse partie du code vient de cette application !

Dans ce cas, pour ton probleme, je n'en sait rien .. .désolé.


Concernant directX, j'aime pas trop, car tourne que sur windows !! 

Ah le bon vieux Bill ... ;-) Il ne fait que des trucs qui ne fonctionne que sous Windows. C'est normal, c'est la politique Microsoft ...
C'est pour cela que personne n'aime mais que tout le monde subit ... en attendant mieux des autres developpeurs (on en fait peut-être partie lol).

Pour revenir au sujet, regardes les differences entre tes deux Exe ...
