Hi all, I am currently using OpenFlight files to load all of my scene graph content and would like to perform some collision tests at specific nodes.
Ideally, what I would have liked to do is to backward traverse (up in the node's parent direction) the scene graph from that specific node up to the root node of the SG, while accumulating the transformations encountered. Is this already support somewhere? If not, I think it would be a great addition to the functionalities of OSG and makes it very easy to work with the transforms in the SG. I am pretty new to the nodeVisitor idea so I am still pretty much in a learning and figuring out mode. I saw about the NodePath object and its getNodePath() function but am unsure how that could be helpful here. Can this getNodePath() provide me a path from a given child node to the root? What do you mean by: "Get the non const NodePath from the top most node applied down to the current Node being visited." What is the top most node and the current node being visited in a specific scenario? How do I set these two points? Does any kind soul could give me some hints / examples, even partial, as to how this could be implemented in code?
