Fish-disk 588 content: FracBlank

Tuesday, October 20th, 2009

A commodities screen blanker written for AmigaOS release 2.x. When running will blank the screen and start to draw real plane fractals such as described in the September 1986 issue of Scientific American. The resulting images may remind you of spiders’ webs, lace or even the Chladnian patterns formed by grains of sand strewn across a vibrating surface. This is version 1.8, an update to version 1.4 on disk 535, and includes numerous bug fixes and enhancements (such as multicolor mode). Includes source in `C’ and assembly language.

Fish-disk 588 content: FifoLib

FIFO: is like PIPE: but is based on fifo.library rather than its own implementation. Fifo.library is a general fifo library implementation that supports named fifos, writing to a fifo from a hardware exception, multiple readers on a fifo with each getting the same data stream, efficient reading, and automatic or manual flow control. Programs that require non-blocking IO can access one side of a FIFO: connection via the fifo.library instead of the FIFO: device. Version 3.4, an update to version 3.1 on disk 519. Includes some source. Author: Matt Dillon

Fish-disk 588 content: MandelSquare

Tuesday, October 20th, 2009

Yet another program to generate images from the Mandelbrot set, different from most implementations in that it runs only under AmigaOS 2.x, requires an ‘020/’030/’040 CPU and a numerical coprocessor. The calculation routines were written in ‘881 assembly language for maximum speed and precision. Also included is a `movie mode’ which allows generation of long camera zooms to spots in the Mandelbrot set. The resulting animations can be saved in ANIM-opt-5 format, allowing to replay them using `MandelSquare’ or standard animation software. Version 1.3, includes source in `C’ and assembly language.
