PureBasic

j'espère que ça marchera pour tout le monde cette foi !
la dernières version d'opengl (4.6) étant plus pointilleuse, la plupart bug si on ne définit pas le "fog", je l'ai donc ajouté au exemple
#PB_Material_ColorShader et #PB_Material_PerpixelShader peuvent présenter un défaut d'ombrage noir.
#PB_Material_PointSpriteSphereShader peut planter
pour ces 3, j' ai mis un exemple réécrit (avec CreateShadfer)

Hello Guillot.

Test des quatre codes. Cette fois çi c'est parfait. Bravo.

Heu, le 3eme code fait une ombre un peu bizarre sur le tore.

merde !

j'ai fais une petite modif sur le 3e code, tu peux retester et me dire si c'est OK ?
sinon tu peux me mettre une copie d'ecran (est ce que la transition entre texture fonctionne ?)
et me donner ta version opengl
pour ça falsam à donner un petit code:

Code 3 :

Même "problème". Ce n'est pas "moche" mais je ne pense pas que tu l'as fais exprès.

merci pour ton aide
effectivement c'est bien un défaut l'ombrage noir en dessous du torre
j'ai fait des modifs, si tu peux tester, me dire si tu as toujours le probleme
si oui, peux tu m'envoyer le contenu du débogueur ?
(si tu enregistre le code préalablement, le débogueur pourra te donner plus d'info en cas de probleme de compilation du shader)

effectivement c'est bien un défaut l'ombrage noir en dessous du torre
j'ai fait des modifs, si tu peux tester, me dire si tu as toujours le probleme
si oui, peux tu m'envoyer le contenu du débogueur ?
(si tu enregistre le code préalablement, le débogueur pourra te donner plus d'info en cas de probleme de compilation du shader)

Même problème. Exactement pareil que le GIF de falsam ci dessus...

merci les gars,
falsam, je suis un peu étonné qu'avant, c'était nickel sur tout les exemples
peut etre que le bug de l'exemple 3 se voyait moins
dans la version modifiées pour SPH j'ai augmenté la luminosité ambiante, et pris des textures plus claire pour mettre en évidence le bug

j'ai modifié le code en virant la gestion de l'attenuation de la lumiere (et viré le debug), je vous laisse tester...

M'enfin

Voici un petit gif du rendu de tes quatre premiers codes de ce sujet avant tes corrections.

Je ne voyais pas de souci d'ombre sur le torus.

t'es le pro tu gif animé !
sur l'exemple 3 on voit le probleme d'ombrage
et le bump ? (dernier post)
