Title: mandelbrot 24K x 16K

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.

I wonder how many time it took to render...

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.

that is a bit small

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

with 10x supersampling it was 240000x160000 that got rendered though so still feels kinda big   ;D

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?

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

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!!!!
