%description
Mandelbulber2 is an easy-to-use, user-friendly yet experimental application
for visualizing 3D Mandelbrot fractals. Mandelbulber2 provides a wide range of
effects such as: Complex 3D shading: hard shadows, background occlusion,
ambient overlay, fog, depth of field. Also includes a video editor and
keyframe animation of all floating point options.

%description -l ru_RU.UTF-8
Mandelbulber2 — это простое в использовании, удобное, но экспериментальное
приложение для визуализации трехмерных фракталов Мандельброта. Mandelbulber2
предоставляет широкий спектр эффектов, таких как: Комплексное трехмерное
затенение: жесткие тени, окклюзия фона, окружающее наложение, туман, глубина
резкости. Также включает видеоредактор и анимацию ключевых кадров всех
параметров с плавающей запятой.
