Hello
Can you please explain me how does Horde's scene graph automatically choose nodes to be grouped and "childed". Or it doesn't do it, we have to do it manually?
One more, how are the shadows culled? With sweep tests?
Thanks

Basically you are building the scene graph yourself since it represents the structure of your world. In Horde models are also scene graph branches. Of course you don't need to create these yourself but can use a tool like ColladaConv. For rendering, the nodes are collected in a list which can be sorted by depth or materials to reduce state changes. |
