🙄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

Let’s be real: You’ve probably seen a list like this 1,000 times. It looks repetitive, maybe even "dumb." But here is why it actually matters for you: When you only have one word for everything (like "Good"), your brain "glitches" when you're trying to speak fast. You hesitate because you're searching for variety but your "vocabulary folder" is empty. 🧠 The Secret to Speaking Fast:🛫 Fluency isn't about knowing the hardest words; it's about having options. When you have 3-4 ways to say the same thing, your brain doesn't have to stall. It just picks the next available word and keeps the flow going. - #English#SpeakEnglish#EnglishTips#Vocabulary#SpokenEnglish
