Just wanted to run a large mandelbrot render for the hell of it. 24k x 16k, 10x supersampled, 100k maxiter, DE-ish style render. 14mb png, zipped just so it doesnt accidentally load in a web browser. http://filebin.net/11gm2ceqhh/Mandelbrot.Set.24Kx16K.png.zip Title: Re: mandelbrot 24K x 16K Post by: Glitchraptor on March 21, 2015, 08:57:15 AM I wonder how many time it took to render...

Your image couldn't be opened. :snore: :hurt: errmsg: "Please upgrade your device and softwares and OS" Title: Re: mandelbrot 24K x 16K Post by: blob on March 21, 2015, 11:22:15 AM I can view this (not very interesting) image fine in XnView on my Windows ME with 2GB of RAM, I doubt you've got a lower specs system. It uses just 1.1GB of RAM which is roughly the amount of bitmap data this image weighs. IrfanView and FastStone Viewer both choke on it though.

(http://3.t.imgbox.com/GIJPY3ZW.jpg) (http://imgbox.com/GIJPY3ZW) 24000x16000 is about a medium size i am currently working a a 15.6 Gig single image ( not a fractal) 92160 x 46080 32 bit float the image software i used in that screen shot is Nip2 it is DESIGNED for use with BIG multi gigabit images Title: Re: mandelbrot 24K x 16K Post by: quaz0r on March 26, 2015, 02:37:20 AM Quote 24000x16000 is about a medium size with 10x supersampling it was 240000x160000 that got rendered though so still feels kinda big ;D Quote the image software i used in that screen shot is Nip2 VIPS is an interesting program, i saw how they started using it on sites like wikimedia to handle downsampling very large images. if i ever want to support rendering ridiculously huge images that make imagemagick crawl or explode i was planning on converting my code to use vips and seeing how it fares. so out of curiosity what is your large image that you are working on? Title: Re: mandelbrot 24K x 16K Post by: JohnVV on March 27, 2015, 04:33:20 AM using the MESSENGER spacecraft at Mercury PDS images to do a 256 pixel per degree map of the planet this is not the largest i did a 131,072 x 65536 pixel map after reprocessing the Magellan radar data to remove the stripping from the Synthetic Aperture Radar removing this stripping from http://nssdc.gsfc.nasa.gov/imgcat/html/object_page/mgn_c115n009_1.html http://nssdc.gsfc.nasa.gov/imgcat/html/object_page/mgn_c314s300_1.html to this (http://1.t.imgbox.com/bmqNrt0B.jpg) (http://imgbox.com/bmqNrt0B) (http://2.t.imgbox.com/X6sKbzFz.jpg) (http://imgbox.com/X6sKbzFz) the map of mercury is not done yet . the poles need a ton of work . IM is dead slow .It has to read the WHOLE image into ram first libvips and Gmic both sample a area and move on to the next the gui Nip2 dose take some time to learn it is a bit " odd" when working on such BIG images i tend to have some fun with Mandabulber , Structure_Synth and Fragmentarium or a few other things for Something DIFFERENT!!!! |
