Hi,
I'm actually in my second year for a diploma in IT. We curreently work on a
group project using OpenSceneGraph.
We're making a turn by turn tactical game. On our map, we want to load some
trees. We have a .obj model (soon .osg) and use osgDB::ReadNodeFile to load it,
and put it in a PositionAttituteTransform with the good pos.
The problem is that it took some time to load the model (around a second)...I
try to avoid it by copying the already loaded model, using the clone function
of osg::Node in a for loop, and puting the cloned node inside a newly created
PositionAttituteTransform ...
But only one tree apears on the map.
If i use each time osgDB::ReadNodeFile in the loop, it works, i've got my tree,
but it took ~ 5 second for 5 trees....
Here's my code, maybe more clear than my english...
Code:
//Loading of the model
osg::ref_ptr<osg::Node> Arbre = osgDB::readNodeFile("modeles/arbre.obj");
osg::ref_ptr<osg::PositionAttitudeTransform> temp;
for(int i = 0 ; i < 5; i++)
{
temp = new osg::PositionAttitudeTransform;
osg::Node* copy = dynamic_cast<osg::Node*>(Arbre->clone(osg::CopyOp()));
temp->addChild(copy);
temp->setPosition(myPos);
this->addChild(temp.get());
}
"this" is my class which inherit from osg::Group.
Did i use it wrong? Is it not possible to copy a node loaded byt
osg::ReadNodeFile?
Thank you![/code]
