David Buck - Blog: Comments Entry As many of you are aware, I wrote a raytracer called DKBTrace back in the late 1980's. I wrote it in C on the Amiga (using a few ideas from Smalltalk), ported it to Unix and eventually released it as freeware. DKBTrace had really caught on but they were frustrated that Aaron and I weren't adding features fast enough to DKBTrace. www.cincomsmalltalk.com /userblogs/buck/blogComments?entry=3306173249   (345 words)

POV-Ray - Wikipedia, the free encyclopedia It was originally based on DKBTrace, written by David Kirk Buck and Aaron A. Collins. Interested, he played with it for a while, eventually deciding to write his own raytracer, named DKBTrace after his initials. In 1987, Aaron Collins downloaded DKBTrace and began working on a x86-based port of it. en.wikipedia.org /wiki/Povray   (1543 words)

The Early History of POV-Ray They liked my DKBTrace raytracer but didn't like the fact that I was too slow adding new features to it. They were going to re-write a raytracer from scratch, but I suggested that after version 2.12 of DKBTrace, they could take the code as is and develop it from there into a new raytracer. He donated the rights to his source code so the PV-Team could enhance this raytracer as a group project similar to Fractint. www.math.sunysb.edu /~sorin/online-docs/povray/html/povdoc_028.html   (2223 words)

POV-Ray: Source-Code History POV-Ray is based on DKBTrace, a raytracer originally written by David K Buck in 1987, and subsequently co-developed by David and Aaron A Collins between 1988 and 1991. In 1991 David and Aaron made the decision to allow the source code of DKBTrace to be used as the basis of a new raytracer, which was to be called POV-Ray. Code that has been introduced as a result of a programmer taking a previously-existing version of the source code and working with it in order to be able to create the code that they eventually contributed. www.povray.org /sch   (873 words)

DKBTrace  DKBTrace was a graphical ray tracing program which was the forerunner of POV-Ray. It was written for UNIX by David K. Buck (1986) and Aaron Collins. The last version (DKBTrace 2.12) was built in 1989. www.javvin.com /softwareglossary/DKBTrace.html   (66 words)

POV-Ray@Everything2.com It is generally considered one of the best raytracers around, and has many advanced features commonly only found in very expensive graphics software, such as caustics, radiosity, isosurfaces and much more. POV-Ray has its roots in a raytracer called DKBTrace, written by David K Buck for the Amiga in 1986. By 1989 DKBTrace had turned into the first version of POV-Ray, thanks to David K Buck's suggestion of forming a development team for improving the program. everything2.com /index.pl?node_id=11399   (779 words)

POV-RAY Tutorial POV-Ray stands for “The Persistence of Vision Ray-Tracer.” It is an open source ray-tracing program that began as an extension of DKBTrace, a ray-tracer developed by David K. Buck and Aaron A. Collins in the 1980s (1). In 1989 with the release of DKBTrace 2.12, Buck and Collins were feeling the pressure of their increasingly popular ray-tracer as their users expressed desires for more and more new features. A group of volunteers known as the POV-Team, mostly previous users of the DKBTrace system including both Buck and Collins, combined forces to add the desired features to the program and update its documentation. ida.colby.edu:3000 /povray   (457 words)

ASCII by Jason Scott: The Render Junkie Somewhere after the explosion of the Amiga Juggler, came DKBtrace, a command-line raytracer for the Amiga written by David K. Buck and which dropped, into my waiting hands, the ability to actually do raytracing. I learned the arcane DKBtrace language and how to do light sources (you created a sphere and colored it what was needed and then declared it a light source) and all the rest of it, and I could raytrace before I turned 20. When I released DKBTrace 1.0, my feeling was that I had fun my with it and I'd release it as freeware in case anyone else was able to have fun with it as well. ascii.textfiles.com /archives/000510.html   (1908 words)

NewsForge | POV-Ray illustrates complexity of changing licenses All this despite the fact that the POV-Ray licenses are relatively similar to the GPL, Cason said, adding that the only reason the rendering software is not licensed under the GPL in the first place was the original developers' lack of knowledge of its existence. Although the POV-Ray project started in 1991, the software's roots are in DKBTrace, an application started in 1987 by developer David Buck, according to the code history on the POV-Ray Web site. Buck licensed the software "to be used freely by end-users, and freely distributed, as long as it was not sold, included with a commercial program, or used in certain other ways that contravened the concept of the software being freely available," according to the history. software.newsforge.com /software/06/01/17/201221.shtml?tid=132   (2203 words)

Smalltalk ray tracing As some of you may know, I wrote a ray tracer many years ago (1986) called DKBTrace. The original DKBTrace (and even the modern POV-Ray) benefited from some object oriented ideas taken from Smalltalk which I had learned even earlier (1984). I recently decided to write a very simple Smalltalk raytracer to demonstrate the basic techniques. www.cincomsmalltalk.com /userblogs/buck/blogView?showComments=true&entry=3243310836   (194 words)

ACCU Reviews: Practical Ray Tracing in C Although the reader is expected to be a PC user, much of the information is generally applicable and DKBTrace has been ported to many platforms. The second section is a gentle tutorial in the use of DKBTrace, a much more advanced ray tracer than that produced during section one which makes use of texture mapping, bounding volumes, CSG and input script files. The text states that some of the more advanced examples given take over thirty hours to produce on a 33MHz 486 when used with high resolution output; lower resolution output and less complex modelling reduce the time required to more manageable amounts, but the results are still far from instant. www.accu.informika.ru /accu/bookreviews/public/reviews/p/p001018.htm   (547 words)

Ray Tracing News, Volume 4, Number 3 One of my larger projects that I want to attempt is translating the C source for DKB to assembly and hopefully gain some speed. The public-domain raytracer DKBTrace, which runs on FPU-equipped Macs, has been made available for anonymous ftp from "alfred.ccs.carleton.ca", files /pub/dkbtrace/dkb2.12/other_ports/MacPort1.0.2.*. In the balls, gears, and tree databases, the ground plane is moved outside of the 22^3 grid in an attempt to generate a more uniform object distribution within the grid. jedi.ks.uiuc.edu /~johns/raytracer/rtn/rtnv4n3.html   (5734 words)

Roy Melton: Research Projects   (Site not responding.

Radiance Based on a raytracing engine, it is used to produce numerically acurate results as well as to visualize designs, run comparative simulations or create artistic work. I was first confronted with raytracing software in the early nineties, using simple but yet astonishing software (dkbtrace, the father of the still famous povray) on DOS-based PC, when the first releases of Radiance just started their calculations on the most powerful workstations available at the time. Later during my studies of architecture, my interest in simulation started to grow, and I wrote my first small tool to calculate water and temperature distributions in walls and roofs (instead of doing the calculation manually). www.larsgrobe.de /projects/radiance/index.html.html   (268 words)

Ray Tracing News, Volume 4, Number 1 I've placed a new version of DKBTrace onto alfred.ccs.carleton.ca (134.117.1.1) for beta testing - and for those who just can't wait :-). DKBTrace is a freely-distributable raytrace program that renders quadric shapes, CSG (Constructive Solid Geometry), and a handful of other primitive shapes. DKBTrace also allows you to define complex an interesting solid textures such as wood, marble, "bozo", etc. The texturing facility has been greatly enhanced in version 2.10. www.ccp14.ac.uk /ccp/ccp14/ftp-mirror/povray/pub/povray/Ray-Tracing-News/rtnv4n1.html   (16056 words)

Information Home At the time I was using a program called 'DKB Trace' which was the predecessor for the ray tracing engine now known as POVRAY. Some of the following pictures were done with DKBtrace and Povray, with an assortment of different other programs to produce textures and models. Mainly I used DeluxPaint, Photoshop, and a modelling program for POVRAY known as MORAY. www.buji.net /maincoll.htm   (150 words)
