For those it might be useful for, I've created a Makefile and a Visual Studio 2005 project for lz-kdtree you can find [http://www.stanford.edu/~lthendri/cs348b/lz-kdtree_build.zip here].  The Makefile will build lz-kdtree.so, and the VS 2005 solution will build Release/lz-kdtree.dll and Debug/lz-kdtree_d.dll.  I find this kind of setup useful if you want to keep lz-kdtree.cpp in a "local" directory outside the pbrt source tree (e.g., in a cvs repository without the rest of the pbrt source).  Note that you'll have to add your own copy of lz-kdtree to the Sources in the VS solution file, and you'll have to change the path in the Makefile on line 10 to point to your own copy of pbrt.



=== Q.1 Default Killeroo Scene (DougJohnston) ===
Using the scenes includes in the zip file, I get the following statistics:
{{{
Geometry
    Total shapes created                                    532.2k
    Triangle Ray Intersections                              673.8k:4826.8k (13.96%)
    Triangles created                                       532.2k
Kd-Tree Accelerator
    Avg. number of primitives in leaf nodes                 3.965M:1.376M (2.88x)
    Interior kd-tree nodes made                             1.376M
    Leaf kd-tree nodes made                                 1.376M
    Maximum number of primitives in leaf node               284
}}}
which is significantly different from those in the project description.
