Rendering in manual strips by IDeviant Rendering in manual strips by IDeviant
Released nicely in time for the results announcements of the Benoit Mandelbrot Fractal Art Contest 2009, this should remove any nagging doubt that, should your Apophysis flame be selected, you won't be able to render it to the required dimensions. A tutorial with scripts, this guides the artist through the stages necessary to produce huge poster-sized renders without overly taxing the PC. Anyone who's used the built-in method of rendering in strips either knows, or has an idea, that the render time is multiplied by the number of strips. Not so here: the total render time is the same as rendering in one would be, if suficient RAM were available to the system. The only stumbling block that remains is the memory handling of your chosen image software for assembling the final work...

Calling also upon the latest flam3 beta, I was able to render a 108 Mpx work in 3 strips in a mere two and a quarter hours. The assembly took less than 15 minutes (normally a matter of seconds) after two optimisations of the process and a re-write of the instructions!

Edit: I just learned a completely brilliant method of assembling the final image using IrfanView. If the final part was giving you doubts or headaches, please re-download - what took 15 minutes in the GIMP was about 10 seconds using the new method!

I found this script can not be used in 3d effect. especially used depth blur and perspective.
do you have a idea to solve it ?

Hmm, now that's quite a surprise! Those particular features must somehow refer to the whole fractal, so there'll not likely be any way to break it down whilst retaining the original effects :(

yes,i feel this is very hard.

Hi was struggling a lot to get larger sized render with Apophysis 7x 15c.9 on my core i5 quad processor. I was limited to ~3000X3000 pix with oversample 3, filter radius 0.7 and density 20000.

Thanks for your script it is very handy. I am going to render a test case.

Hope it works out! I also have an experimental script that breaks a flame into squares, but it's not fully tested yet...

I wish that will work too.

I'm sorry ,I test your script late.
I have test it ,then i collection two advices.
1.When run this scipt ,set the desired size.only set the width or the height,then the other keeps zoom auto.
and the tile size only for the input desired value.the other keep again.
2.Dose have one software can combine these pics into a picture?
Use the method that you write in Patchwork_rendering.PDF,must repeatedly many times.

I'm struggling to fully decipher this. Not sure either if the comments refer to the strips or squares method.

1. I'm aware that the patchwork (squares) method doesn't allow for an initial non-zero zoom value - this needs correction. The purpose of introducing zoom is to preserve image quality.
2. The assembly software is IrfanView [link] There may exist other softwares that allow assembly in one operation, but I'm not aware of them.

I'm this ambitious yet but am curious! Thanks so much. :heart:

Thank you for the tutorial.
IrfanView has been my favorite program for years!
This option of creating "Panorama images" is extremely handy also to build tutorials, combined with the options of resizing and adding borders.
