Ray-tracers

• 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 informatik.
• 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 (scoy@microsoft.com). 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• DKBtrace - an older ray tracer, superceded by PoV-Ray.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.

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:

	balls	gears	mount	rings	teapot	tetra	tree

POV 1.0	191000	1775000	409000	260000	45000	31000	250000

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):

	balls	gears	mount	rings	teapot	tetra	tree
Art/Vort	2.54	5.30	1.45	1.63	1.62	2.00	2.34
Art/Vort +float	2.21	4.55	1.25	1.38	1.40	1.71	2.01

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.
