Computer graphics FTP site list

Computer graphics related FTP sites (and maintainers), 5/17/94
	compiled by Eric Haines, [email protected]
	and Nick Fotis, [email protected]

First are listed various computer graphics related resources, with a particular
focus on 3D rendering and modelling.  As this list grew out of the Ray Tracing
News, I focus on this topic first.  At the end are the FTP sites for all
software and more.  Here's the table of contents:
	Distributed/Parallel Raytracers
	Renderers which are not raytracers, and graphics libraries
	Modellers, wireframe viewers
	Radiosity renderers
	Volume renderers
	Geometric viewers
	Data Formats and Data Sets for Ray Tracing
	Written Material on Rendering
	Image Manipulation Libraries
	Libraries with code for graphics
	FTP Sites


RayShade - a fast ray tracer for workstations on up, also for PC, Mac & Amiga,
	has Linda parallel language support and distributed network support
	programs; however, the package has not evolved much lately and the
	author (Craig Kolb) has been too busy to fold in bug fixes and have
	one official version, so things are a bit scattered at this point.
POV-Ray - Persistence of Vision ray tracer, now at version 2.2.  Offspring and
	successor to DKB Trace, written by Compuservers.  Probably the best
	free ray tracer on the IBM PC, partly because of the many programs which
	support it (e.g. Moray, POVCAD, L-Parser, CTDS, etc etc etc).
	There is also FTPOV-Ray, which is a faster (unofficial) POV at
Polyray - a shareware IBM PC ray tracer, object code only, but very popular
	among users; has nice features for animation generation.  Its
	programmer, Alexander Enzmann, also works on PoV-Ray, so features in
	it tending to migrate to PoV.
Radiance - see "Radiosity", below.  A physically based ray tracer, heavily
	emphasizes realistic lighting and shading models.  Excellent package,
	well supported and works on many platforms.
ART - ray tracer with a good range of surface types, some interesting solid
	texture functions; part of VORT package.
RTrace - Ray tracer by Antonio Costa, does bicubic patches, CSG, 3D text, etc.
	IBM PC and Mac versions also exist.  Imports many different model
	formats.  Also attaches to Bernard Kwok's radiosity package.
VIVID2 - A shareware raytracer for PCs - binary only (286/287).  Author:
	Stephen Coy ([email protected]). The 386/387 (no source) version
	is available to registered users (US$50) direct from the author.
	"Bob" is a subset of this ray tracer, source available only through
	disks in "Photorealism and Raytracing in C" by Christopher Watkins
	et al, M&T Books.
Microcosm - Nice commercial rendering system using scripting language, from
	vector representations to ray tracing.  Demo available on net.
BRL-CAD - A ray-tracer, CAD package, and much more from the Ballistics Research
	Laboratories.  Evidently has a fair-sized, dedicated user base.  Free,
	but you must register it before use.
RAY4 - Steve Hollasch's 4-dimensional ray tracer - renders hyperspheres,
	hypertetrahedra, hyperplanes, and hyperparallelepipeds (there's
	a separate real-time wireframe viewer written in GL called WIRE4 ) .
DKBtrace - an older ray tracer, superceded by PoV-Ray.
MTV,QRT,DBW - yet more ray tracers, some with interesting features, but old.
	There are a lot more than these, but these are the ones which are
	"free" and have some user base.

Which one's the best?  Here's a ray tracer feature comparison of some of the
more popular ones.  I assume some basics, like each can run on a Unix
workstation, can render a polygon, has point lights, highlighting, reflection
& refraction, etc.

A "." means "no".  Things in parentheses mean "no, but there's a workaround".
For example, POV 1.0 has no efficiency scheme so takes forever on scenes with
lots of objects, but there are programs which can generate efficiency
structures for some POV objects (also, in this case, POV 2.0 will fix this

Timings - default size SPD databases (i.e. up to 10,000 objects in a scene),
time in seconds on HP 720 workstation, optimized and gprof profiled code.
Includes time to read in the ASCII data file and set up.  Note that profiling
slows down the execution times, so real times would be somewhat faster in all
cases (about 30%); plus, the profiler itself is good to +-10%.  Also, these
timings are purely for this machine - results will vary considerably depending
on the platform.  Now that I've explained why these are useless, here goes:

The gears and mount tests are probably worth ignoring because everyone handles
shadows for transparent objects differently.  Some consider them opaque to
shadows, others handle it differently.

Here are timing ratios (i.e. 1 is the fastest time for a given test, with
the other timings normalized to this value):

Art/Vort was compiled with and without a "+f" compiler option; with it on
floating point numbers are not promoted to doubles during expression
evaluation (and so things runs noticeably faster).  Other packages may benefit
from such compiler options.

Rayshade had some minor user intervention.  The ceiling of the cube root of
the number of objects in the scene was used as the efficiency grid resolution.
For example, balls has 7382 objects:  cube root is 19.47, ceiling is then 20,
so a 20 x 20 x 20 grid was used.  Rayshade needs hand tweaking of the grid
structures for extra efficiency (esp. with balls and tree), though this is
fairly simple for the SPD tests (i.e. leave the background polygon out of the
grid structure).  Tweaking in these cases means leaving ground plane polygon
(if it exists) out of the grid structure.

Radiance is quite different in its approach, as it is more physically based.
Efficiency structures are built in a separate program (so the time spent doing
this is not included in the above stats).  Also, Radiance outputs in a
floating point format (which can be quite handy).

RTrace is often a bit faster when the "c6 m0" options are used.

POV 2.0 has an efficiency scheme built in and so is comparable to the others,
so don't get freaked out by the POV 1.0 performance numbers.
