[comp.graphics] SPD version 3.0 now available, with teapot

erich@eye.com ( Eric Haines) (12/19/90)

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,
