Computer graphics related FTP sites (and maintainers), 12/12/94 compiled by Eric Haines, erich@eye.com and Nick Fotis, nfotis@theseas.ntua.gr 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: Ray-tracers 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 Animation Players Paint Programs Libraries with code for graphics FTP Sites WWW sites 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. 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". Rayshade POV 2.0 RTrace Radiance Bob ART IBM PC version? Y Y Y in 2.2 Y Y Amiga version? Y Y . Y . (Y) Mac version? Y Y Y A/UX .

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 Art/Vort 478 1315 239 595 235 84 381 Art/Vort +float 415 1129 206 501 203 72 327 Rayshade w/tweak 188 360 174 364 145 61 163 Rayshade w/grid 1107 412 174 382 145 61 1915 Radiance 289 248 165 601 150 42 197 Bob 402 747 230 831 245 50 266 RTrace 664 1481 813 1343 341 153 372 RTrace c6 m0 652 1428 811 1301 331 155 363 POV 2.0beta+ 588 1895 668 1113 306 56 542 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 Rayshade w/tweak 1 1.45 1.05 1 1 1.45 1 Rayshade w/grid 5.89 1.66 1.05 1.05 1 1.45 11.75 Radiance 1.54 1 1 1.65 1.03 1 1.21 Bob 2.14 3.01 1.39 2.28 1.69 1.19 1.63 RTrace 3.53 5.97 4.93 3.69 2.35 3.64 2.28 RTrace c6 m0 3.47 5.76 4.92 3.57 2.28 3.69 2.23 POV 2.0beta+ 3.13 7.64 4.05 3.06 2.11 1.33 3.33 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. Distributed/Parallel Raytracers: -------------------------------- XDART - A distributed ray-tracer that runs under X11.
