🙄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. #qt#source#tricks
