XThis is version 4.0 of rayshade, a ray tracing program.
XRayshade reads a multi-line ASCII file describing a scene to be rendered
Xand produces a Utah Raster Toolkit "RLE" format file containing the
Xray traced image.
X
XRayshade features:
X
X	Eleven primitives (blob, box, cone, cylinder, height field,
X	plane, polygon, sphere, torus, flat- and Phong-shaded triangle)
X
X	Aggregate objects
X
X	Constructive solid geometry
X
X	Point, directional, extended, spot, and quadrilateral light sources
X
X	Solid procedural texturing, bump mapping, and
X		2D "image" texture mapping
X
X	Antialiasing through variable-rate "jittered" sampling
X
X	Arbitrary linear transformations on objects and texture/bump maps.
X
X	Use of uniform spatial subdivision or hierarchy of bounding
X		volumes to speed rendering
X
X	Options to facilitate rendering of stereo pairs
X
X	Rudimentary animation support
X
X
XThere are many differences between rayshade versions 3.0 and 4.0.  In
Xparticular, the input syntax has changed.  Input files created for
Xversion 3.0 must be converted to version 4.0 syntax using the provided
Xconversion utility, rsconvert.  See Doc/Changes for a list of some of
Xthe more important changes.
X
XRayshade v4.0 has been tested on many different UNIX-based computers,
Xincluding: SGI 4D, IBM RS6000, Sun Sparcstation 1, Sun 3, DECstation,
XApollo DN10000, NeXT.  If your machine has a C compiler, enough memory
X(at least 2Mb), and runs something resembling UNIX, rayshade should be fairly
Xeasy to port.  Be warned that rayshade uses yacc and lex to process input
Xfiles.  If you do not have lex and yacc, try to get flex and bison from
Xthe Free Software Foundation folks (ftp to prep.ai.mit.edu).  Attempts
Xto port rayshade to 16-bit machines will likely lead to nothing but
Xa profound sense of frustration.
X
XRayshade uses a Configure script in order to determine how it should
Xbe compiled.  This means that if you're not runing under UNIX, you'll
Xprobably have to create a config.h and edit the Makefiles by hand.
XIf you create a config.h file and/or Makefiles for use in an non-UNIX
Xenvironment, send them to us and we will make it available for use by
Xothers.  The prototype config.H file may be of some help.
X
XNormally, rayshade makes use of the Utah Raster toolkit.  You are
Xstrongly encouraged to get a copy of the toolkit, as it provides a
Xhost of useful tools for image manipulation and a library for reading/writing
Xthe toolkit's "RLE" format image files.  "blurb.urt" is the "blurb" file from
Xthe latest distribution of the toolkit.  Also of interest is the
X"fbm" library, available from nl.cs.cmu.edu:/usr/mlm/ftp/fbm.tar.Z, which
Xprovides additional tools for converting Utah Raster format images
Xto/from other formats.
X
XIf you do not want to or cannot use the Utah Raster toolkit, rayshade
Xcan be configured to create image files using a generic format
Xidentical to that used by Mark VandeWettering's "mtv" ray tracer.
X
XThe rayshade distribution consists of two libraries (libray, libshade) and
Xseveral applications (rayshade proper, rayview, raypaint) that are
Xlinked against these libraries.  To compile, run the Configure script to
Xgenerate config.h and the Makefiles, then run "make depend"
Xfollowed by "make".  If the Configuration script fails, or if
Xit can't determine a way to generate dependencies, you'll probably
Xhave to edit the Makefiles or extract them from the Makefile.SH scripts
Xby hand.  Don't be overly alarmed if there are a few non-fatal error
Xmessages while running "make depend"
X
XThe Doc directory contains a User's Guide in the Guide subdirectory,
Xas well as a quick-reference sheet and some information that might
Xbe useful in porting or modifying rayshade.  To create a formatted
Xversion of the User's Guide, you'll need LaTeX.  If you don't have
XLaTeX, a postscript version of the Guide is available via anonymous
Xftp from weedeater.math.yale.edu (see below).
X
XThe etc directory contains miscellaneous goodies, including the source
Xto a filter to convert rayshade v3.0 input to rayshade 4.0.
XThe Example directory contains example input files, which may be
Xused to test rayshade and to familiarize yourself with rayshade's input
Xsyntax.  You can also run any one of Eric Haines'
XStandard Procedural Databases through awk using the etc/nff2shade.awk
Xscript, and then feed the results to rayshade.  Note that for several
Xof the databases, you will need to tweak the data a bit to achieve
Xoptimal runtimes.  See nff2shade.awk for details.
X
XRayshade was not designed to be, nor is it, the be-all and end-all of
Xray tracers.  It was meant to be reasonably fast, portable, and easy to
Xmodify.  It has some nice features which allow you to produce
Xpretty pictures, but there are countless extensions, modifications,
Xand improvements which could be made.  There are many routines which may be
Xoptimized and many features which could be added.  For a list of suggested
Ximprovements and projects see "TODO".  You are strongly encouraged to modify
Xthe source code left and right.
X
XWhile there is currently no documentation for the libraries, it
Xshould be easy for you to add your own primitives, textures, aggregates,
Xand light sources by looking at the code and sending mail if you get
Xstuck.
X
XAdditional rayshade goodies are available via anonymous ftp from
Xweedeater.math.yale.edu (130.132.23.17) in pub/rayshade.4.0.
XIf you have contributions of new objects, textures, input files,
Xconfiguration files, or images to make, feel free to send us email or
Xto drop off a copy via ftp in the "incoming" directory on weedeater.
X
XThe first version of rayshade was written by Craig Kolb, David P. Dobkin,
Xand David C. Hoffman during 1987-1988, and was heavily based on an
X"introductory" public domain ray tracer written by Roman Kuchkuda.
XRayshade v3.0 was written by Craig Kolb and released in the Fall of 1989.
XRayshade v4.0 was written by Craig Kolb and Rod Bogart during 1990-1991.
X
XRayshade was made possible by many people who have made suggestions,
Xfixed bugs, and who have been all-around good sports about the whole thing.
X
XThanks to Gavin Bell, David Dobkin, Eric Haines, Lefteris Koutsofios,
XKen Musgrave, Przemek Prusinkiewicz, and Allan Snider for their
Xencouragement, comments, and willingness to be on the Front Lines.
X
XThanks to Roman Kuchkuda for providing such a solid base upon which
Xto build.
X
XSpecial thanks to Robert Skinner for providing the Noise(), DNoise(),
Xand other texturing functions and allowing them to be redistributed.
X
XPat Hanrahan's OOGL provided the spirit (if not the letter) of the
Xmodularity of rayshade v4.0.  Thanks to Pat and to Mark VandeWettering
Xfor the 'net tracer' conversations and for the inspiration to do something
Xto clean up rayshade.
X
XThanks to Marc Andreessen, Tony Apodaca, Ray Bellis, Dominique Boisvert,
XWilliam Bouma, Allen Braunsdorf, Jeff Butterworth, Nick Carriero,
XNancy Everson, Tom Friedel, Robert Funchess, David Gelernter, Mike Gigante,
XEd Herderick, John Knuston, Raphael Manfredi, Lee Moore, Dietmar Saupe,
XIain Sinclair, Brian Wyvill, and everybody else for their bugfixes,
Xsuggestions, input files, encouragement, and other feedback.
X
XThanks also to Mark Podlipec for providing the blob and torus objects.
X
XThanks to Jochen Schwarze for the cubic and quartic root-finding functions.
XHis code, and a host of other useful routines, can be found in
X"Graphics Gems", edited by Andrew Glassner.
X
XThanks to Benoit Mandelbrot for the support he provided this project.
X
XIf you find any bugs, make any useful extensions, have a nice input file,
Xport rayshade to a new environment, or need assistance understanding a
Xparticularly braindamaged section of code, please let us know.  We can be
Xmost easily reached by email.
X
XOnce you start using rayshade, and you'd like to be kept abreast of
Xchanges and extensions, send a message to rayshade-request@cs.princeton.edu,
Xand we'll add you to the rayshade mailing list.

XRayview reads a rayshade input file and opens a graphics window into
Xwhich images are rendered using GL (SGI / RS6000) library calls.
X
XSupport is provided for most rayshade primitives and light sources.
XSupport for CSG is limited to drawing the bounding boxes of those
Xobjects used in each CSG object.
X
XRayview is intended to be an example of the kind of application program
Xthat can be written using the rayshade libraries.  You are encouraged
Xto improve or otherwise modify rayview to suit your needs.
X
XTo compile, edit the Makefile, set GRAPHICSLIB and SPHERELIB appropriately,
Xand run make.
