In shader code, How do I use the quadtree data structure? I has a quadtree data outside of shader code. But I want to use it in the shader code. How do I do that? Has any website or book or paper talk about this?

I think you use a quadtree in your program, on the CPU to determine what chunks of geometry you have to send to the GPU. Therefore your shaders have nothing to deal directly with the quadtree itself.
