Version 3.0 of the Standard Procedural Databases generation package is now available. This package is a set of seven C programs, each of which generate a scene description (i.e. view, lights, object colors and locations, etc) for testing the efficiency of your ray tracer. The databases provided are: balls - fractal ball object (a.k.a. sphereflake) gears - 3D array of interlocking gears mount - fractal mountain and 4 glass ball rings - pyramid of dodecahedral rings teapot - the famous teapot on a checkerboard tetra - recursive tetrahedra tree - tree What's new: The famous "teapot" database has been added to the set. It can be generated with or without the bottom, at various mesh resolutions. // All the database generators allow an optional command line argument, which must be a positive number. This number is the Size Factor, which determines how many objects the database generated contains. So, "balls 1", for example, will output just 10 spheres on a square, while "balls" will generate the default 7381 spheres. // All code has been regrooved to be a tad faster and more consistent (though looking back on it, I don't think I would have bothered...). // mountain.c is renamed to mount.c to make some micro users happy. // README is much changed, with clarifications and new statistics. The NFF description has had some clarifications made. You can get the code by two methods. One is via anonymous FTP: weedeater.math.yale.edu [130.132.23.17] cs.uoregon.edu [128.223.4.13] Currently the code is in SPD.3.0.shar.Z, and is located in /incoming - it'll probably move to some more permanent spot soon. For those without FTP access, write to the netlib automatic mailer: research!netlib and netlib@ornl.gov are the sites. Send a one line message "send index" for more information, or "send haines from graphics" for the latest version of the SPD package. You should probably wait a few days before trying this out - I've sent the updated package, but haven't had confirmation on it being installed yet. The package is about 108K unpacked (i.e. via email), about 48K compressed. Enjoy, Eric Haines, erich@eye.com
