<p>Полный список возможностей рендерсистемы Hydra renderer.</p>
<p>Hydra Renderer - это система фотореалистичного рендеринга общего назначения.
Она имеет открытый исходный код и бесплатна для коммерческого и некоммерческого использования,
по самой либеральной MIT лицензии. Она может работать как на центральных, так и на графических
процессорах (однако предпочтение отдается графическим). Мы позиционируем нашу систему
как высокоэффективное средство визуализации для моделирования сложных явлений переноса света.</p>
<p>Нашими основными преимуществами являются двунаправленные алгоритмы рендеринга и алгоритмы марковской
цепи: Kelemen Metropolis Light Transport и Multiplexed Metropolis Light Transport.</p>
<p>Гибкое API позволит вам интегрировать Гидру в ваше приложение, а программируемые шейдеры кастомизировать визуализацию.</p>
