🙄Разминка для ума!
Треугольник Серпинского, интересная фигура которую построить достаточно просто.
Алгоритм такой:
1. создаём любые 3 точки на плоскости
2. из этих точек случайно выбираем любую, как начальную
3. случайно выбираем любую точку из этих же трёх точек как цель
4. перемещаемся в сторону цели на половину расстояния
5. повторяем бесконечно с пункта 3
Если сделать достаточно много итераций то вырисовывается интересная фигура. Треугольник, в который вписаны более мелкие треугольники. Это самый настоящий фрактал!
Я собрал пример построения такой фигуры на базе Qt.
🌎 Код можно посмотреть здесь.
С помощью paintEvent я рисую точки по озвученному алгоритму. Каждые 10 секунд либо по клику на виджете строится следующий треугольник.
Особенности примера:
🔸 Атрибут Qt.WA_OpaquePaintEvent позволяет сохранить то, что было нарисовано в прошлой итерации. Таким образом мы видим постепенное наполнение точек а не мелькающую одну точку.
🔸QTimer позволяет создавать отложенные вызовы один раз или с повторением через интервал.
🔸QColor.fromHsv() позволяет создать рандомный но предсказуемый цвет с помощью HSV схемы. Не слишком светлый и не слишком тёмный но всегда с разный. Рандомизации подвергается только смещение по цветовому кругу (Hue), яркость (Value) и насыщенность (Saturation) можно контролировать отдельно в своих пределах или оставить статичными. Обычный рандом цвета по RGB не даёт такой предсказуемый результат.
🔸 Каждый новый цикл с новым треугольником предварительно затемняет предыдущие через этот вызов
painter.fillRect(rec, QColor(0, 0, 0, 100))
То есть полупрозрачный цвет. Таким образом, чем старше треугольник, тем он темней.
Если сделать виджет фулскрин, то у нас получится некий ScreenSaver)))
🔸 Да, я знаю, что рисование в Qt не самый лучший способ сделать этот пример) Скорее всего самый НЕподходящий. Попробуйте сделать тоже самое но другими средствами.
