Fractal program. Calculates enlargements of the Mandelbrot set and the Julia set on screen and on the printer. Fully exploits the capabilities of the ST and has very extensive image processing capabilities. All time-critical program parts are written in machine language, which guarantees high speed. Special options: Display of a finished image in several gray scales on the screen, scrolling through an oversized image, or as a printout on a 9 or 24-pin printer. Three-dimensional display of the calculated depth values as 'lake' or 'mountain' with any setting of the tilt or rotation angle.
