How to get the real position of a sub node in SceneKit after rotation?

Question

I am developing a scene with SceneKit. I have a main node with a subnode:

// Main node
SCNNode* planet = [SCNNode node];
planet.geometry = [SCNSphere sphereW         


        

Answer 1

The node's position won't change due to physics, that is why you aren't seeing it change. You need to call the node's presentationNode to get the position of the node as it is presented onscreen:

node.presentationNode.position
