+[measure-one](measure-one): A number of frames converted from Beeple's
+amazing [Zero-Day](https://vimeo.com/140163198) animation. Converted from
+Cinema4D files downloaded from [Beeple's
+website](http://www.beeple-crap.com/resources.php). (Note that the original
+materials and lighting is much better--improvements to our conversion 
+gratefully received!)

+"These files are available under a sort of "open source" concept. They are
+intended for educational use but really can be used for whatever the fuck
+you want. You don't need to credit me for whatever commercial or
+non-commercial use you make of them, but if you could shout me a holla with
+any project that do come from them, I'd love to see it :)"

+Conversion notes:
+
+Frames were exported from Cinema4D using the pbrt exporter. (It's important
+to change the logging level in the export dialog to "Error", since
+otherwise many messages are generated and it seems that c4d has some sort
+of O(n^2) thing going on there, since exports slow to a crawl.
+
+Geometry fiels were then converted to use PLY meshes using "pbrt
+--toply". There are many repeated meshes (both shared across multiple
+frames but also identical meshes within a single frame. These were boiled
+down to unique messages using the following go program, which prints a
+script for "sed" to stdout.
+
+package main
+
+import (
+	"crypto/sha256"
+	"encoding/hex"
+	"fmt"
+	"io/ioutil"
+	"os"
+)
+
+func main() {
+	for _, fn := range os.Args[1:] {
+		contents, err := ioutil.ReadFile(fn)
+		if err != nil {
+			fmt.Fprintf(os.Stderr, "%s: %v", fn, err)
+			continue
+		}
+		sum := sha256.Sum256(contents)
+		str := hex.EncodeToString(sum[:]) + ".ply"
+		fmt.Printf("s/%s/%s/g\n", fn, str)
+		err = os.Rename(fn, str)
+		if err != nil {
+			fmt.Fprintf(os.Stderr, "%s: %v", fn, err)
+		}
+	}
+}
+
+The pbrt geometry file that --toply emitted was then updated to use the
+hashed file names generated by the go program:
+
+% sed -f out.sed < ply-geometry.pbrt > g.pbrt
+
+Note that the sed script has thousands of lines and sed seems to be quite
+slow--it takes many minutes to run the sed script, even though the geometry
+file is only around 4.5MB.
+
+To add all of the light sources, use the lights.sed script:
+
+% sed -f lights.sed < g.pbrt > g-lights.pbrt
+
+Finally, rename g-lights.pbrt to something sensible and update the Include
+in the main pbrt file for the frame to use it. More generally, replace
+everything after the Film directive in the generated pbrt file up to the
+geometry Include with the text from one of the other frame files.
+
+Whew
