Welcome to the Quintessential Sophistry Home Page


Visit the QS image gallery.

This is a collection of ray tracings, fractals, attractors, other pictures derived from mathematical patterns, and a few miscellaneous items. Please note that most of the pictures utilize true color 16.7-million-color graphics modes. Therefore, if your browser and/or image viewer are not set to a true color mode, the pictures will be dithered in some way or other and might not look particularly aesthetic.

DOS Programs

[VL]
Here is some information about some of my fractal-generating programs for DOS.


32-bit Windows Programs

[QSWF] [QSSX]
[QSWL] [QSF]

QS W95 Fractals generates images of various fractal types in dimensions up to 1600 x 1200. If you are running a true color graphics mode, it can draw 24-bit pictures directly on the screen and save them to Targa files. It also can draw standard 256-color pictures and save them to GIF files. It utilizes some of the new Windows 95 features, and it has typical options such as zooming, color-cycling, inversion mapping, binary decomposition and several inside and outside coloring methods. It features some fractal types described in The Beauty of Fractals, The Science of Fractal Images and The Fractal Geometry of Nature which are not commonly found, including Volterra-Lotka, enhanced sine, "Escher-like tiling" of Julia sets, magnetism formulae and "self-squared dragons".

SymXaos plots the various attractors described in Symmetry in Chaos by Michael Field and Martin Golubitsky (Oxford University Press 1992). It generates images using each of the five attractor formulae found in the book. It also can plot high resolution images up to 1600 x 1200 and save them as GIF files.

QSW LIC is a Line Integral Convolution program. In summary, LIC is an image processing technique in which pixels are blurred along the "stream lines" generated from vectors that describe how the image changes, usually according to factors such as brightness or HSV value. Although developed for the scientific visualization of vector fields, this technique can be applied to many types of images for aesthetic effects as well. The online help file contains a more thorough explanation of the concepts behind this technique.

QS Flame is a free-standing program which plots the beautiful attractors created by Scott Draves, which he describes as "cosmic recursive fractal flames". Images can be saved to disk as GIF or TARGA files, depending on the graphics mode. The program uses 256-color palettes derived from standard Fractint MAP files. The colors are blended by a filtering algorithm in true color modes. The parameter sets of individual images can be saved as small binary files to allow re-rendering of the images. This program supports the GNU concept of free software. Accordingly, the source is available. NEW! By popular demand, image dimensions now can be set by the user with no upper limit, and an option for indefinitely-long iteration looping has been added. Now you can run the thing all night long if you want.

You can see several examples of images rendered with all 4 programs in my image gallery.

These are 32-bit programs and will not work with Windows 3.X. The zipped archives are 345, 133, 446 and 178 KB respectively. No wizards required; just extract the files into the directories of your choice.


Fractint Makefiles

[FRACTINT]
If you're interested in compiling your own version of Fractint with a Borland C++ compiler more recent than version 3.1, here is a set of command line makefiles that works for versions 4.52 and 5.01. I'm working on some project files for the IDE, but there are some linking problems with the overlay option. Even with the command line method, the version of TLINK.EXE that comes with version 5 does not work, and you'll need to replace it with the one that comes with version 4.5.
