3D Mandelbrot and Julia Set Viewer - New Link


threading improvements

colour list now details iterations per pixel for mandelbrot generation

minor bug fixes

new 'Fractal Equation' setting - will be expanded in future releases

added colour smoothing

removed some settings

new colour models

see readme.txt

sub-sampling - nicer pics

bug fix


new formula

Added: Press S while mouse is over mandelbrot plot to save image as PNG

Added: new slider control under colour scheme list to set minimum plot size

Faster 64-bit floating point plot

Fixed bug with arbitrary precision floating point plot (plot image corrupt)

Changed key to F for saving mandelbrot plot as PNG

Press F while mouse is over julia plot to save as PNG

Press F while mouse is over 3D model to save as PNG

Added sub-sampling for julia set, optimised for noisy areas only. 64 to 256 sub-samples produce good results. The highest setting can be very slow.

When the ctrl key is down and the mouse is moved over the mandelbrot, the julia set will now only be automatically plotted when using the 1st or 4th equation on the settings screen.

Two new colour models 'Ice' and 'Lava'

Fixed: Save (to PNG) of 3D render could result in corrupt or incomplete images.

Small speed improvement for the sub-sampling pass.

16 February 2010
There will be further updates to this application. For the forseeable future they won't be as frequent as recent updates. Things have just picked up a bit in my job so I won't have so many free evenings and weekends.

I do plan to add a feature to create zoom videos. A lot of the work has already been done but it needs more testing and I need to implement a UI mechanism for specifying filenames and numbering for the temporary images created on disk. The feature will also need a pause/resume mechanism, which will require state to be stored.

At some point I'd also like to add other rendering mechanisms such as 'bhuddabrot', and 'true 3D' model generation (possibly involving voxels - need to do more reasearch). Obviously I'll be adding more colour models. I want to tidy up the UI some more and add a proper mechanism to store plot details and settings.

Also documentation, a nicer skin, and perhaps even a website and/or release as open source. It's a pet project, and I'm aware of some of the astounding products out there. But this is free and hopefully some people like it.


Added new equation 'z = z^2+c bhuddabrot' - the larger the plot the more detailed the picture - best results with a colour model that starts with black.

Added 3 new colour models for bhuddabrot plots.

Small fix to bhuddabrot plot. Better plot when no, or a low level of, sub-samples are used.
Bhuddabrot plot can now be run across multiple threads.

Fixed 3D model of bhuddabrot plots
UI Change: A rendered julia set can now be explored when the bhuddabrot equation is selected (previously disabled).
UI Change: Changing the colour model will immediately update any displayed plot(s), and will cause any previously rendered 3D model to be regenerated.
