Vocaldo(taps@rmx.com) - Macintosh port INTRODUCTION: XaoS is a fast portable real-time interactive fractal zoomer. It displays the Mandelbrot set (among other escape time fractals) and allows you zoom smoothly into the fractal. Various coloring modes are provided for both the points inside and outside the selected set. In addition, switching between Julia and Mandelbrot fractal types and displaying planes is provided. The first version was a poorly written Mandelbrot view by Thomas later modified by Jan to support high frame-rate zooming. Other additions were later made including autopilot (for those of you without drivers licenses), palette changing, PNG saving, and fractal inversion.

This may be slow on some computers. The program was developed on a Pentium running at 120 MHz, but it can work quite well (20fps) on 486Dx/2. I also received nice letters from users using XaoS at 386/40 or so. Coprocessor is _REALLY_ required. Faster computer is better so alpha/600MHZ recomended. To compile XaoS you need ANSI compliant compiler with _GOOD_ optimizations. Unix version uses configure script. Other platforms uses different ways. GNU CC is highly recommended. Graphics drivers usually have some additional requirements. (for example xlib for X11, djgpp and allegro for dos port) Also fast malloc/free routines are recomended because they are called quite often (10 times per frame). For full featured XaoS (with image saving code) you also need zlib and libpng.
