Biggest rendering?

[Rhinoc]

I am just curious as to the largest size of renderings anyone has completed and how many hours.......... ..............days................................ .........................................or weeks it has taken them. I have a 5072x2464 that has been rendering for about 30 hours now and is only 63% done.

Ryan,

I assume you mean a ray trace? What happens if after it's done you are not satisifed with it??? That's my one big problem with doing too much ray tracing. It is tough to get all aspects the way you like and it consmes so much time. ANd also ties up the computer!

the answer could be from minutes to days...there simply are too many variables for any answer to be definative....

size of the model;

complexity of details used in the model(moldings, trims, cabinetry, fixtures, furniture, millwork, etc);

render settings (radiosity, reflectivity, etc) of the various materials used in the model;

render settings when sent to the renderer(radiosity, anti-alliasing, soft shadows, etc)

computer system itself :

cpu, drives, memory (speed, amount, etc), bus speeds of the mobo

what other programs are running in th ebackground, or other work you may be doing while the render takes place...

Ryan,

I did a large Chief Architect Raytrace rendering ONCE.
It was a 7200x10800 pixel at 300dpi for a 24"x36" construction drawing package cover.

To get the pixel size multiple the print size by the desired dpi. 300dpi is considered good quality for photos.

Raytrace time is a function of your CPU, amount of RAM, the number of lights, bump maps and "random energy in the air".

For my case: 3.2GHZ PIV-HT w/2G RAM. Raytrace settings were High Quality Anti-aliasing and High Quality Radiosity. Sunlight was only light source. The image also had some bump maps for selected materials.

[color=red][size=4]It took 76 hours![/size][/color]

The Pentium IV with HyperThreading really paid off in this job. At least I could keep working on other projects.

I think the largest one I ever did was 10,000 x 6,000. It probably took a full day. I'm sure I ran it at low radiosity.

[Rhinoc]

For this project I had to add some interior lighting to show the art glass windows and I set it for the High Quality Anti-aliasing and High Quality Radiosity as they may blow it up even larger to try to gain more interest ( money) from their congregation.

I definitely agree with Don's statement; "The Pentium IV with HyperThreading really paid off in this job. At least I could keep working on other projects."

By the way 66% done.

I am in the middle of a project that requires 16 renderings (8 Front/Side elevations and 8 Rear/Side elevations)

I am running the Fronts at 1200x900 and the Rears at 800x600. I am including lighting in each shot (typically 6 or so lights per shot). I am still experimenting with radiosity levels (none, low, medium, high) - I have deterimined that AA needs to be at high for what I am doing.

At times no radiosity seems to be fine. Sometimes it is too bright. But, low and meduim radiosity shows too may "artifiacts" (mold) and I am not willing to wait the time necessary for a High Radiosity, High AA, 6 light rendering @ 1200x900 rendering (sometimes 36 hours or more).

I am not sure that I answered your question here, but at least I let you know that there are others out here with the same questions and concerns.

BTW ... I am running my renderings on 3 computers right now. 1) P4 - 3GHZ 1GB RAM - No HT
2) P4 - 3GHZ 512MB RAM - No HT
3) Celeron - 2.8GHZ 512MB RAM

There is a noticable difference in performance between each of the PC's. The biggest step is between the P4 and te Celeron. Just thought you might want to know ...

Zoome.

What monitors are you using?
Prices of each?
5072x2464?
7200x10800?
10,000 x 6,000?

Mike,

Who is your question directed towards? or Just a general question ...

Dan, do you mean renderings or raytracings? If I understand it right, they are profoundly different.

Sounds like Raytracing to me. Renderings don't take more than a few seconds, are video card dependent, and are limited to monitor resolultion. Ray tracing on the other hand uses the CPU, can take days, and can be bigger (pixels x pixels) than the monitor.

Thanks

I mean Raytraces.

The biggest single screen computer monitor I know of is the 30" Apple Cinema-VU which is 2560 x 1600 if I remember right. It costs around $2,500 plus or minus depending on sales, etc.

Fitch - If the largest monitor is 2599 x 1600 as you say, where does the extra resolution come from?
Answer Edited - - OK - I re-read your answer and so that question is answered.

Is anyone using the 30" Apple?
Is there any advantage over using twin 1600x1200 monitors?

I am developing specs for a new system and want to replace my twin mismatched (20"/1600x1200 & 19"/1280x1024) monitors.
I am looking for suggestions.
Good equipment creates higher productivity, so I am prepared to spend a little more for above average equipment.

I'm using twin 1600x1200 20" LCDs that are razor sharp. The single apple monitor would have a continuous screen that would be an inch bigger than these two monitors turned 90 degrees (portrait mode) and pushed together with out the monitor border in the middle of it. I'd love that. I'd just run these monitors on either side of it for secondary applications.

The only thing that holds me back is the cost of the Apple monitor + the video card it takes to drive it (about $3K). If I was doing this to make a living I'd have already done it. As a hobby ... oh well, one has to have a dream.

Ryan,

The largest raytraces I do for color cover work on prints is 6144x 3495 on the POV Ray v. 3.6 stand-alone. The lines and textures are clear and sharp, so have never needed to go larger for Arch E1 (42x30). The rendering times vary, but the longest I have ever had go is 6 hours and 15 min. This was on a pretty large model with lots of tree shadows on full radiosity and raytrace. I think the single light source helps more than anything on speed. Hope this helps.
