Mandelbulber 0.97

[Buddhi]

Mandelbulber 0.97 - for Linux x86, Linux x64 and Win32

Open source program (GNU GPL) for rendering photo-realistic 3D fractals

Free download: http://sourceforge.net/projects/mandelbulber/

Website: http://sites.google.com/site/mandelbulber/

New features in version 0.97:
- Improved rendering of timeline thumbnails. Now thumbnails show what exactly will be rendered during animation rendering.
- Added refresh button in timeline window
- Added rendering of interiors of fractals (Interior mode). When it's enabled the fractal is rendered as a thin crust (unfortunately rendering is very slow  )
- Added edit fields for changing distance of minimum and maximum distance of view
- Improved accuracy of raymarching
- After image rendering there is visible "failed DE" value on progress bar. This value informs how many oversteppings were occurred during rendering.
- Added "Fractal constant factor" which modifies constant value in all fractal formulas by multiplying by this factor.
- fixed bug: program crashed when path for keyframe files was changed and Timeline window was opened

Before first run please use install script

The install script executes src/Release/mandelbulber instead of copying (or installing) it.

Fix the sudo line like so:

from:

Code:

sudo src/Release/mandelbulber /usr/bin

to:

Code:

sudo install src/Release/mandelbulber /usr/bin

(Note this is not a recursive call to the install script provided by mandelbulber but a call to the system install command which at its simplest works exactly like cp but also sets appropriate attributes).

The interior mode is awsome !!
We can isolate the boundary of a fractal set.
I'm confident you will find a way to make is faster.

Thank you for information about this bug. I have corrected it.

I like this a lot, but I am unable to make the animation work like the instructions indicate. Unless I use the Init3d navigator button, as soon as I click "record path" the fractal disappears and "closeup" in the view tab is set to 0. When I do use the Init 3d Navigator button, the program freezes, and when I try to use keyframes, it crashes and closes. I am running the latest version on a PC with XP. Any ideas?

buddhi! awesome software, as always!

but... i have trouble with the new "interior mode": it goes like this:

i open some settings file like the one attached below. image parameters say 384x216.
then i render the image.
next, i just change the image parameters to 192x108 - everything else unchanged.
i would expect the same image just scaled down, right?
but in fact, it looks like *zoomed out* and scaled down!
this is not the behaviour i would have expected, but maybe i got something wrong?

changing parameters to 704x396 the image looks like zoomed *in*...

when i have not checked "interior mode", then everything works as i would expect it:
no zoom in or zoom out just scaled out or scaled in.

this is why i *think*, that there is trouble with interior mode. (but it could be other paramters as well)

if it's a bug, then i hope i have explained it enough so you can locate it (if not: just ask for more details!), if it's not a bug then please tell me, what i am doing wrong!

cheers,
f.

here's the fract-file (just some mandelbox with quite standard parameters):

buddhi! awesome software, as always!
but... i have trouble with the new "interior mode": it goes like this:

Hi

Rendering of images with interior mode is so difficult. It is because this mode enables rendering of only very thin fractal "skin". For better understanding how it works please try to render "interior - mandelbox scale 2.fract" or "interior - mandelbulb power 8.fract" first with interior mode and next without this option. As you see this surface is really thin and in this case difficult for raymarching algorithm.
Some parameters which you used were not correct.
- resolution you set to 2. It is too high value, because it produces too thin surface. Try some other values on default example "interior - mandelbox scale 2.fract" settings file. If you use value 0.2 you will see thick "skin" and when it will be 1.0 or higher the "skin" will be very thin.
- DE step factor was also too high (2.0). Higher value means less accurate ray-marching. It should be about 0.5 or less. You should also reduce Shadings effects/glow parameter because lower DE step factor produces more intense glow.
- I don't know why you have used "minimum iter" = 17. It caused these strange changes of image when you changed image resolution. Lower image resolution needs less iterations for rendering so some parts fractal disappeared, because didn't achieved minimum number of iterations
- camera was located not in fractal interior but between some parts of fractal.

[fastrail]

buddhi: thanx for this fast answer! i will try to follow your instructions!

i was not aware that setting all those parameters is so crucial in combination - obviously, i was just playing around with some settings without knowing whats going on.

keep on the good work!
