Hi,

i did something similar and recognized that i takes some time until the model is inserted correctly. Assuming you use

world_->InsertModelSDF(modelSDF);


you could wait a bit

common::Time::MSleep(500); // sleep half a second


before printing out all models. Also make sure the simulation is running and not paused. To access all models you can do something like:

for(std::vector<T>::iterator mod = world_->GetModels.begin(); mod != GetModels.end(); ++mod){
printf("Model Name: %s",mod->GetName());
}

Two Edits to my Answer. They are probably not necessary! But i add them if someone runs in similar problems and the things above are not working:

MSleep(500) cause the thread to sleep, this may be problematic (or maybe not, depends :P). If its not working try to use:

  world_->Step(500);


std::vector<physics::Model>::iterator mod = ......
