SceneKit：使用dae动画更新SCNGeometry

Question

I decided to use SceneKit for an awesome iOS project. But i found a big issue.

In my application, i load some animated .dae. It's well displayed. But the SCNGeometry of the node don't update, during the animation. I tried to check the presentationNode, but still the same. How can i get the updated value of the geometry ? Like vector.

Answer 1

That is how I can do it:

SCNNode * mainNode = [[SCNNode alloc]init];
SCNScene * scene = [SCNScene sceneNamed:sceneNamed inDirectory:some/path/where/you/have/it options:nil];

for (SCNNode * node in [scene.rootNode childNodes]) {
    [mainNode addChildNode: node];
}

It should work in most cases if your DAE file contains animations.
