#4 days rendering time!!!

Wow! I`ve blown up 3D-Studio Release 3! I rendered a image from our new Anti-Aids commercial where are about 8 condoms on a street in front of a wall and a trashcan. Nothing moves. The condoms have different colors and one wears a sunglass. I used two spot-lights with raytraced shadows (only one illuminates the condoms). The mappings needs about 12 megs of RAM. I rendered the scene in 720×578 on a Pentium/66 with 64 megs RAM. After 3 days I had to cancel the rendering because I needed the PC. After this 3 days only 3/4 of the rendering was done… What can I do to reduce rendering time? I`ll render the same scene with shadow-maps tonight. But you know that shadow maps doesn`t look as good as raytraced shadows from a transparent object 🙁 BTW: in the final version the condoms have to jump through the street… Michael – Michael Bassier, Written 18-Jul-1994 @ 08:46:06 Using: Windows NavCIS PRO 1.2

It sounds like perhaps you created a very large ray-tracing quad-tree in that scene. The first thing I'd do would be to set my max-shadow-levels down to5-6 in the 3ds.set file. Have you seen that parameter yet? (it's mentioned in the R3HIDN.TXT file here in the DL's) – G

Yes, I have downloaded the R3HIDN.TXT file but I thought I wouldn`t need it… (mea culpa 🙂 ) I`ll try it again with a max-shadow-leves of 5 tonight… Michael – Michael Bassier, Written 19-Jul-1994 @ 08:42:25 Using: Windows NavCIS PRO 1.2

Hi Gary! I`ve set down the Max-Shadow-Levels to 5 and this speeds up rendering a little bit (a few percent) but it still needs close 4 days to render the image. I`ll raytrace the image with RayMan and let`s see how much time it needs 🙂 Michael – Michael Bassier, Written 20-Jul-1994 @ 08:59:24 Using: Windows NavCIS PRO 1.2

Maybe someone is trying to tell you something…. Hmmmmmmmm!

Let this be a lesson to us all: Practice safe rendering…. Marc

Hi Mickael I just thought I would mention our rendering services. If you want details on this and sample rendering times (that will be updated soon) download the file supplied in the want adds in the file section of autodesk multimedia. I would guess that we could render your animation with the jumps, mapping etc. Just the way you want it in 24 hours or less and have it back to you by courier on video tape of your choice or files on the media of your choice. If this sounds interesting to you please leave me a note. thanks for taking the time to read this. Mark Rasmussen MIPS Computing Centre

Hi Mark! Rendering Service sounds good. Maybe we`ll need it someday… I think it could be expensive to send the projects files from Germany to USA and back. Ok I can send you the files via email (is there a special price when I send 20 megs via email? 🙂 ) but the tape should come via mail. Can you record PAL- Betacam SP tapes (I believe you can…)? If so please send me additional information to the following adress: VisArt Computergrafik GmbH Essener Str. 5 46047 Oberhausen Germany Phone: +49 +208 202151 Fax: +49 +208 202251 Thanks in advance.

For sending big files you should use internet. The price is good ($0.00 <g> – thought I don't know about 20megs…) John Tissavary (LUNA cie)
#113716From: Paul LindJul 20, 1994 3:07 AM
We've sent files much larger than 20 megs across the NET. It's pretty straight forward. There are also a number of ways to divide a single file into multiple parts and then once they arrive at the other end, they can be reassembled. Paul

>> The price is good ($0.00 … That's if you're a student or an employee. Ask the one paying the bill to see how cheap that is! <g>

I'm new to sending files via internet… I have an account through a provider that charges $22 per month (14,4, where not talking slip, isdn, or t1 here) and was under the impression that file transfers were part of the deal, as long as I don't exceed my hours/month allotment… am I missing a key peice of info here (very possible <g>)?

John, I saw your e-mail on the Net but I haven't had a chance to get to it. As to sending binary files on the Internet, you simply need to uuencode the file into multiple pieces so that all mail servers will be able to use it. Most mail servers have limits as to message sizes. There are a number of ways to do this. More than likely the easiest way for you to do it is to upload the file to the host system and then activate a binary transfer through whatever front end they're using. Almost all "dial up" services have binary e-mail transfers set up so that the host system will automatically take the file, split it, uuencode it, and send it to the respective party. If you prefer to handle the uuencode yourself, simply download one of the 100 different uuencode/uudecode utilities off of the net. Then after running uuencode send the multiple files to the intended recipient. Paul P.S. – If you don't know how to find an uuencode/uudecode utility on the Net, let me know and I'll e-mail it to you here on CIS.

Big time thanks, Paul. I think the files I'm sending can be e-mailed, they'll likely be under 2 megs (but I'm not totally sure about that). I'll ask my provider wether the e-mail binaries get uuencoded by the host. always grateful… John Tissavary (LUNA cie)

John, Glad to help…… sorry I didn't get to the Internet e-mail quicker….. but we're sorta busy. 🙂 Paul

Sorta busy? I know what you mean. I'm sorta busy too =-) John Tissavary (LUNA cie)

I was mostly teasing you. You said it yourself, $22/month ain't free (though quite a trip from a T1). There are all kinds of ways to send files across the net. It depends what you use to access it. You're probably using a standard comm program and accessing someone's system (that's Telnet). You probably have your "Home" directory in this system. From there you can start another telnet session with the computer you want to send the files to (assuming they give you an account) and send the files through Zmodem (type sz to send and rz to receive) than just fire your Zmodem protocol. If you don't have an account to "Telnet" into, do what Paul said, but instead of UUENCODING the file before you upload to the "middle" system, get a utility called "GZIP" in the unix forum and zip the files locally. Once you transfer them to your "middle" man, unzip it there (GZIP is in almost every unix box out there) and run UUENCODE on the host computer. That way you save 4 to 8 times the transfer time. All UUENCODE does is get every byte of the file and make it a valid 7 bit ASCII character. That means doubling the file size. This can go on and on… It depends on what kind of connection you have. If you're interested, I can give you a very loooong description on how to do this.

>>>am I missing a key peice of info here (very possible <g>)? If you're doing the sending, you're not missing too much info, but if you're receiving, you should make sure your provider doesn't rape you on the "storage fees". My old provider (I'm at school now… I like free thing$) would charge me on a weekly basis as soon as I got over 1.5 megs in the account. Because of their "starting materials", a number of text files about the internet, I had 5 megs in my directory for a number of months – expen$ive.
#114217From: John TissavaryJul 22, 1994 2:51 PM
That's kind of how I thought it worked. The customer gets a few megs cubbyhole in the server, and has to pay for overspill. I'll call hooked and find out how much mb/$$$ thanks, John Tissavary (LUNA cie)

Hi Michael Sorry if I did not mention it, but we are from Canada. So I don't know how the exchange would be. I didn't know you were from Germany. The answer your question about the 20 meg files, all you would need to do it put it on a floppy disk or some other storage media (we support many different kinds) and courier it to us over night. Then when it is done we would send it back to you the same way. Yes we can record to PAL on BETA-SP. The info will be sent to you. Most of our company details can be found in a file called RENDFA.ZIP on compuserve. Just go to the file area in the autodesk multimedia area and search for it by name and download it. It takes only 2 min or so. It will describe in detail all that we can do. Any more questions leave e-mail here or call at (604) 241-9103 and ask for mark or paul P.S. your very welcome. mark rasmussen MIPS Comuting Centre
