The ‘depth buffer’ should just be mip 0 in a full mip chain of render targets (not the actual depth buffer). Also, DX9 doesn’t actually render anything based on the results. You take the furthest depth value and use it as the new depth in the downsampled pixel.

For DX11, you can just constrain the shader resource view so that you can both read and render from the same mip chain. In my code I actually found a more optimized solution, by ping-ponging between 2 mip chains one containing even and the other odd levels, and a single branch in your shader code you can get around the overhead of having to do the StretchRect and just sample from a different mip chain based on the even/odd mip level you need. The downsampling is pretty much what you would expect, you take the current pixel, sample one pixel to the right, bottom and bottom right. So large objects in screen space will sample from very high values in the mip chain since they require a coarse view of the world.

You should read the papers to get a firm grasp of the algorithm, but here is my take on the process and some implementation notes of my own. This is the DX11 compute shader version, I decided to use it here since it’s clearer what the intentions are. Here’s an example of a before and after version, black is a closer depth, the whiter a pixel is the further away / higher the depth value.

You’ll also send down a stream of texcoords that will represent x/y pixel values of where to encode the results of the occlusion test for that bound. I’ve sort of figured out how to cull the objects whose shadows you can’t possibly see, but not really. In my code I actually found a more optimized solution, by ping-ponging between 2 mip chains one containing even and the other odd levels, and a single branch in your shader code you can get around the overhead of having to do the StretchRect and just sample from a different mip chain based on the even/odd mip level you need. The hierarchical z-buffer solution presented at GDC borrows heavily from this paper,. Stephen Hill, one of the topics was so cool that I thought it would be fun to try it out.
