🙄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

*FRACTION OF SECONDS* Woke up. I knew I was late. Coz that was my routine. And coz of a simple logic, why be excited to wake up early and go to a place you hate and do something that you hate! I sighed when my mouth tasted coffee before colgate...Ahh! how I love normal days, It was a normal day. At least that's what I thought. Papa was there looking up from the newspaper at me with a sense of pity. I sort of ignored that and walked out through the front door, but the next sight, a brand new beautiful ladybird and an even more beautiful rider, with short black hair waving in the wind, in a skirt that knew well not to cover her beautiful legs... Well I couldn't ignore that! Just a fraction of seconds and I had already captured her. Made her mine. Is this what they call... Oops!! She looked at me. Damn it! She caught me staring at her! I looked away whistling. I looked again, did I see a smile? I heard Mom shouting my name out aloud. I knew I had to rush. As I was rushing inside I heard a loud thud. I turned back and saw the beautiful ladybird lying on the road. It was only a fraction of second, yet my mind talked to me in infinite speed...Somethings...what did he say I don't remember anymore. I remember rushing back to the house. One year I didn't talk to our new neighbour who was an year older than me.Days went by. Mom had started packing things up one evening I came back from school. Papa received his transfer letter. Now whenever I see a cycle I think. What would've happened? Why hadn't I stopped my mind talking to me? Why hadn't I I rushed 'out'side than 'in'side? All in a fraction of second! #JOHN PAUL BENOY #Review

Former US National Security Advisor John Bolton: “Although you could potentially remove the ayatollah, that would leave the IRGC in place, and the government in Iran is the IRGC, while the ayatollahs act as a religious cover or an ideological cover for them. I think Trump is just hoping that this show of American power will intimidate the ayatollahs. If I were still his adviser, I would be happy to tell him that it won’t work. They won’t be intimidated. But Trump really thinks minute by minute; he doesn’t think strategically.” #john#bolton#trump#ayatollah 📱American Оbserver - Stay up to date on all important events 🇺🇸
