Detailed Description

To receive lighting, objects must be decorated by a LightListCallback. Light list callbacks must be added via node->addCullCallback(new LightListCallback). Once a light list callback is added to a node, that node and all its child nodes can receive lighting.

The placement of these LightListCallbacks affects the granularity of light lists. Having too fine grained

light lists can result in degraded performance. Too coarse grained light lists can result in lights no longer rendering when the size of a light list exceeds the OpenGL limit on the number of concurrent lights (8). A good starting point is to attach a LightListCallback to each game object's base node.

Note

Not thread safe for CullThreadPerCamera threading mode.
