Quat generates 3d fractal objects. These objects are Julia sets using quaternions. The package can calculate usual images and stereo pair images for real 3d views, and includes a user-specified true color palette for flexible coloring, 5 iteration formulas, and intersection planes so users can cut open a 3D fractal to see its interior. The program calculates fractals in PNG image format using 24bit true color. There is also a text mode version for batch calculation.
