Ok merci pour ton aide c'est vraiment sympas. Néanmoins il m'affiche la même texture sur tous les layer ... Code c++ :
irr::core::array<irr::video::ITexture*> rendered;
void set_color(array<irr::video::ITexture*> skybox, vector3df RedCoef, vector3df GreenCoef, vector3df BlueCoef,float colorCoeff)
{
for(int i = 0; i<skybox.size(); ++i)
{
irr::core::stringc name = "skybox_";
name += i;
rendered.push_back(driver->addTexture(skybox[0]-> getSize(), name.c_str(), skybox[0]-> getColorFormat()));
rendered.push_back(driver->addTexture(skybox[1]-> getSize(), name.c_str(), skybox[1]-> getColorFormat()));
rendered.push_back(driver->addTexture(skybox[2]-> getSize(), name.c_str(), skybox[2]-> getColorFormat()));
rendered.push_back(driver->addTexture(skybox[3]-> getSize(), name.c_str(), skybox[3]-> getColorFormat()));
rendered.push_back(driver->addTexture(skybox[4]-> getSize(), name.c_str(), skybox[4]-> getColorFormat()));
rendered.push_back(driver->addTexture(skybox[5]-> getSize(), name.c_str(), skybox[5]-> getColorFormat()));
}
for(unsigned i = 0; i<skybox.size(); ++i)
{
irr::video::SColor color;
unsigned char *src = (unsigned char*) skybox[i]->lock(ETLM_READ_ONLY);
unsigned char *dst = (unsigned char*) rendered[i]->lock(ETLM_WRITE_ONLY);
u32 pitch = skybox[i]->getPitch();
u32 bytes = video::IImage::getBitsPerPixelFromFormat(skybox[i]->getColorFormat()) / 8;
for(unsigned x = 0; x<skybox[i]->getSize().Width; ++x)
{
for(unsigned y = 0; y<skybox[i]->getSize().Height; ++y)
{
unsigned char *in = src + (y * pitch) + (x * bytes);
unsigned char *out = dst + (y * pitch) + (x * bytes);
color.setData(in, skybox[i]->getColorFormat());
float r = color.getRed() / 255.f;
float g = color.getGreen() / 255.f;
float b = color.getBlue() / 255.f;
float rsepia = r * RedCoef.X + g * RedCoef.Y + b * RedCoef.Z;
float gsepia = r * GreenCoef.X + g * GreenCoef.Y + b * GreenCoef.Z;
float bsepia = r * BlueCoef.X + g * BlueCoef.Y + b * BlueCoef.Z;
r = colorCoeff*r + (1.0-colorCoeff)*rsepia;
g = colorCoeff*g + (1.0-colorCoeff)*gsepia;
b = colorCoeff*g + (1.0-colorCoeff)*bsepia;
color.setRed(std::min(r * 225.f, 255.f));
color.setGreen(std::min(g * 225.f, 255.f));
color.setBlue(std::min(b * 225.f, 255.f));
color.getData(out, skybox[i]->getColorFormat());
}
}
rendered[i]->unlock();
skybox[i]->unlock();
}
}
Utilisation : Code c++ :
set_color( skybox,
vector3df(0.393, 0.769, 0.189), //RedCoef,
vector3df(0.349, 0.686, 0.168), //GreenCoef,
vector3df(0.272, 0.534, 0.131), //BlueCoef,
0.5f); //colorCoeff
skyboxNode->setMaterialTexture (0, rendered[0]);
skyboxNode->setMaterialTexture (1, rendered[1]);
skyboxNode->setMaterialTexture (4, rendered[4]);
skyboxNode->setMaterialTexture (5, rendered[5]);
skyboxNode->setMaterialTexture (3, rendered[3]);
skyboxNode->setMaterialTexture (2, rendered[2]);
Initialisation : Code c++ :
irr::core::array<irr::video::ITexture*> skybox;
skybox.push_back(driver->getTexture("Daylight_Box_Top.bmp"));
skybox.push_back(driver->getTexture("Daylight_Box_Bottom.bmp"));
skybox.push_back(driver->getTexture("Daylight_Box_Left.bmp"));
skybox.push_back(driver->getTexture("Daylight_Box_Right.bmp"));
skybox.push_back(driver->getTexture("Daylight_Box_Front.bmp"));
skybox.push_back(driver->getTexture("Daylight_Box_Back.bmp"));
set_color( skybox,
vector3df(0.393, 0.769, 0.189), //RedCoef,
vector3df(0.349, 0.686, 0.168), //GreenCoef,
vector3df(0.272, 0.534, 0.131), //BlueCoef,
0.8f); //colorCoeff
scene::ISceneNode* skyboxNode = smgr->addSkyBoxSceneNode(
rendered[0],
rendered[1],
rendered[4],
rendered[5],
rendered[3],
rendered[2]);
Il y a quelque chose qui m'échappe ? ... Bon je viens de ruiner tout mon code ... Après y avoir fait fonctionné, je me suis rendu compte que çà lagait énnormément. J'ai alors pensé charger les 24 textures x 6 textures correspondants chacune à une heure de la journée pour la coloration du ciel et là je me suis perdu et mon programme est planté. Visiblement quand je fais le code suivant les textures ne sont pas appliquées correctement : skyboxNode->setMaterialTexture(0, SkyTexRender[0]); skyboxNode->setMaterialTexture(1, SkyTexRender[1]); skyboxNode->setMaterialTexture(2, SkyTexRender[2]); skyboxNode->setMaterialTexture(3, SkyTexRender[3]); skyboxNode->setMaterialTexture(4, SkyTexRender[4]); skyboxNode->setMaterialTexture(5, SkyTexRender[5]); On ne peut pas réappliquer une texture existante sur une skybox ? (j'ai essayé sur un skydome çà fonctionne) Je me demande si je devrais pas plutot créer 24 skybox et faire toutes les couleurs à la main sur Gimp parceque là je ne vois vraiment pas comment çà peut se résoudre
