Your Largest Render

[Keldor]

Hi! I'm back to working on Flam4OCL! Version 0.40 should be out soon, which brings me to my question:

How big is the largest flame you've ever rendered? What resolution/quality?

To stress test my tiling algorithm, I've been rendering various flames from the Electric Sheep archives at 16,000x16,000 at quality 5,000. I also did one at 12,000x12,000 quality 20,000. Since I've greatly improved large image performance since version 0.36 (mostly due to an improved memory allocation scheme, which allows me to use all available memory on the device, even for ATI cards (I hope - haven't tested this yet)), my render times ranged from 2-3 hours for each image running on a single Nvidia GTX570. Unfortunately, there's a bug in the OpenCL implementation which prevents me from rendering anything larger than ~16,000x16,000; it appears to be a 64 bit issue since this corresponds to 4GB of accumulation buffer. I guess someone on the driver team tried to store a pointer in an int.

I would upload the images for you guys to look at, but they're rather large, as in >400MB each . If anyone's really interested, I can upload one to my dropbox. Also, if anyone has some huge fractals they'd like rendered, I can do it ^.^

I registered here to respond to this post. I have been using Apophysis for some time and spent many hours learning it and generating images I'm satisfied with. I finally tried some large renders and I've been unsuccessful with a variety of problems most "available memory" related, never shows more than 4095MB available. I've tried rendering to a size that would produce a 30"x40" print. I'm almost to the point of exporting to UPR and trying to render the large files in UltraF. I've tried this with both version 14 and 15B.

My specs;

i7 - Q740 @ 1.73Ghz
8GB Ram
GeForce GTX 460M 1.5GB Ram

I came to Apophysis after spending way to much time with what turned out to be a dead end for large renders, KPT Fraxflame. I'm hoping Apophysis isn't going to be another one.

Any help will be greatly appreciated.

Any help with large, high quality renders? It will be much appreciated.

I'd be very happy to learn how to do it for myself.

It appears You're using Apophysis 7x ver. 7X.14 and 7X.15B, which are 32 bit only. If you want to render images over 4 GB, you'd have to download 64 bit version which is 7x.15c, it's the only 64 bit ver. of Apo I know. The problem is, you won't be able to use any plugins or scripts for now. I've downloaded it yesterday and I'm now rendering an 14000 x 14000 image with quality of 10000. I'm after 10 hours and there's still 59 left, but when I think of how will final image look I can wait

Any update on flam4ocl 0.40?
