* DIRECTORY 5 OUT! *
Message #36246
PRC PUBLISHING ANNOUNCES NEW IMAGE DIRECTORY PRC Publishing Inc., in conjunction with The Graphics Forums on CompuServe, is offering the fifth edition of its popular "Best of 'Go Graphics'" image directory in its free Mall store. Containing over two thousand grayscale reproductions of online GIF images and support programs, this…
I've also run out of space on my hard drive this way, but I've never had any real problems. I occationally get bad files, but I think it's strictly the swap file and TGA files (it happens generally when I RESET out of POV). They always clean up fine with…
type Hi Dan, Glad to hear it isn't common. I have stacker on drive C but drive D where the incident occurred is pure IDE uncompressed DOS 5.0 flatland. I am running a 486 33 and have never had anything like this happen before. I don't even know that POV…
Jim, I've run out of harddrive a lot of times (doing animations from batchfiles. Never had anything like that happen. You using any sort of stacker-like compression or anything else unusual? There is 1 Reply. Read action !
#POV Bug?
Message #21298
Hi, I used a batch file with POV to generate graphics while I slept. When I awoke the hard drive I had been writing to was trashed big-time. I suspect it ran out of room, but the partition table, FAT, directories i.e. my whole world were gone. Thank God for…
You can start by attaching some fractal gifs to simple objects to get the hang of image_mapping. From there, play with alpha values to "cut out" pieces of the object within the fractal pattern. Then try some height_fields. The docs are pretty thourough in these areas but if you have…
#POVRay and Fractint
Message #21251
Hi, I just started using POVRay and I am quite fascinated by it. Having played around with some simple shapes I would now like to generate raytraced fractal images. I know how to make 3D projections in farctint and there is of course ray trace option but I am not…
"Image Lab" by Tim Wegner contains a chapter on POV-Ray and is availible now. "Ray Tracing Creations" by Drew Wells & Chris Young is expected next month. Read action !
#POV Books from Waite
Message #21150
In the documentation for POV version 1.0, there was mentioned the release of two books pertaining to POV. The publisher is listed as the Waite Group Press. Are these books out yet? What is the address or phone for the publisher? There is 1 Reply. Read action !
Yeah, I can't believe I'm working on that hack… Sorry for the delay in replying – I just got a coupla of 240Mb SCSI's for my home system… I've really been fighting the "hard disk crunch" (I feel better already). I've been on the "Alternative", but not in some time…
Colin, If you use the +x switch on the commandline, in your povray.def file, or the POVRAYOPT= setting, you can interrupt a trace mid-stream. The file can then be started again with the +c switch. It's all in the docs. The .tga file must be converted to a .gif (again,…
If you interrupt a trace, you can continue it by using the same command line, and adding +c (for continue). If you intend to do this, you should avoid using a large buffer (no more than +b20 or so), because you lose whatever is in the buffer when you break…
#POV Stop Start
Message #20959
My question is there any way of stoping when you need to use the computer to do some work and re-starting where you left off, i use the office PC a 486/33 but some ray take a long time in 1024X768. Do you know if there is a way of…

POV-Ray excells over 3DS when it comes to reflection and refraction, just try to make some curved glass objects and compare. POV-Ray also does more correct shadows, 3DS may make them nice and fuzzy but not that correct . 3DS renders much faster. Erkki Read action !
Thanks for the support there, Eric. Actually, I could hear Xander saying "CHEAPER! HAVE YOU TRIED WRITING A ZBUFFER RENDERER?!?" -Dan Read action !
>>"cheaper" Just say that "cheaper" simply means less time (time=money), and equal in all other respects(*NOT!*). There is 1 Reply. Read action !
Tnx for your enormous reply! PSi. Read action !
Peter, Same as the difference between sports and football. Raytracing is rendering, but rendering is not neccessarily raytracing. Commonly, though, rendering is usually used in the context of "cheaper" 3D methods. (I know I'm gonna catch flak with that word "cheaper", but it's the best word that comes to mind…
Oh, no! From an Indigo to a COMPAQ luggable?!? Banish me to Siberia first!! TGA BBS is Adam Shiffman's "The Graphics Alternative" BBS (Oakland, CA). Check near the end of the POV docs for the phone number. TGA is hub of a terrific graphics network and is the "other" center…
Perfect! Thank you very much Alex K. Read action !
#POV 2.0 Language
Message #20696
Yeah, I'd love to "donate" my original NEC to some needy computer person. The TGA BBS ? Is that the AT&T Targa BBS ? Speaking of access to good stuff at work – they finally got me a computer, an old COMPAQ luggable – bleechhhh. My last job was SGI…
Peter, Hmmmm, that could take volumes. Basicly, Raytracing creates images by simulating the physics of light. We see something because light leaves a light source, reflects off of an object (& gets "filtered" in the process) & enters our eyes. Raytracing works basicly the same way although for practical considerations…
Alex, POV-Ray is available right here in GraphDev in the POV Sources LIB. If you have an IBM PC style machine the files you need are POVIBM.ZIP (the program it's self), POVSCN.ZIP (-lots- of example images) & POVDOC.ZIP (documentation files). As for importing 3DS files, there is a converter. It's…
OK, most things you listed I've known! But: what's the difference between raytracing and rendering????? tnx, PSi. There are 2 Replies. Read action !
Hi there Bill: I've been wondering how I can get a copy of POV-Ray… Can it accept meshes from 3DStudio and render them with ray tracing? In other words, can I create the world in 3ds but just have it render in POV? Thanks Alex K. There is 1 Reply.…
POV-Ray is free while 3DS costs a couple thousand dollars. POV-Ray has no GUI or built-in animation support. You describe objects using the POV-Ray language. POV-Ray is a ray tracer so it does reflection, refraction and accurate shadows. 3DS is z-buffered polygons and doesn't do ray tracing. Read action !
Peter, there is not a whole lot of overlap between them. POV-Ray is a freeware raytracing package, 3D Studio is a (quite expensive) modeling, animation & rendering package. POV-Ray uses text files that describe the "world" to be rendered for input, 3DS has a built in wireframe modeler and can…
#POVRay vs ADESK 3D-Stud
Message #20465
Hi, Can anyone explain me what POVRay can do (rendering and raytracing), what Autodesk 3D-Studio don't can (and vice versa)? I have friends in one of the 2 Autodesk destributors in Austria. Perhaps I can make them interested!! PSi. There are 3 Replies. Read action !
