I am creating an opengl app that loads .obj files but I have some serious problems loading them.
When I'm loading obj files it loads vorrectly but after several redisplays it throws an exception "cannot load texture file" then it stops.
I think It's because I load the .Obj file again and again so I changed the code to load once but now it doesn't draws the texture.
Here's my code:
[source lang="cpp"]GLMmodel* LoadOBJ(int ID)
{
char* modelIDs[6] = {"ko.obj","bou.obj","bouKez.obj","bouLosz.obj","ellen.obj","ellenLosz.obj"};
char* path = modelIDs[ID];
GLMmodel* pmodel1 = NULL;
// Load the model only if it hasn't been loaded before
// If it's been loaded then pmodel1 should be a pointer to the model geometry data...otherwise it's null
if (!pmodel1)
{
// this is the call that actualy reads the OBJ and creates the model object
pmodel1 = glmReadOBJ((char*)path);
if (!pmodel1) exit(0);
// This will rescale the object to fit into the unity matrix
// Depending on your project you might want to keep the original size and positions you had in 3DS Max or GMAX so you may have to comment this.
glmUnitize(pmodel1);
// These 2 functions calculate triangle and vertex normals from the geometry data.
// To be honest I had some problem with very complex models that didn't look to good because of how vertex normals were calculated
// So if you can export these directly from you modeling tool do it and comment these line
// 3DS Max can calculate these for you and GLM is perfectly capable of loading them
glmFacetNormals(pmodel1);
glmVertexNormals(pmodel1, 90.0);
}
// This is the call that will actualy draw the model
// Don't forget to tell it if you want textures or not
)return pmodel1;
}

}
};

Thanks for your help in advance
