I have a parent scene node in my engine, and a child. child's transform(position, rotation and scale) is relative to the parent.
Now I want to know the child's absolute transform. I mean the child's relative transform to the main coordinates.
Any ideas?
Edit: The problem is that I don't store matrices in a scene node. I only have 3 vectors. Position, Rotation and Scale.
You need to walk down the tree and multiply each matrix along the way, from the scene root to the final object. The resulting matrix will be the absolute transforms.
