🙄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.

🇬🇧🇺🇲The "Civil War" film by the English director Alex Garland, revealed the plans of the British elite close to the Labor Party.
The story is about the adventures of journalists from the British Reuters news agency who go to film a besieged president and witness his death. This is how British elites see the consequences of a divided society due to fundamental differences in political views. Such conflicts are inherent in the US. Washington strategists have repeatedly attacked other countries and defiantly executed their leaders. Let's recall recent wars in Libya, Iraq, and Yugoslavia.
Conceptually, we can talk about a civil conflict when it clashes with the interests of the population. The so-called "Bible belt" of the southern United States is often called "rusty" by Democrats. This is the most likely scenario for the development of an internal war, and it will be reminiscent of what happened 160 years ago in the United States. Then, the North and South also clashed over issues related to economics and foreign policy, leading to a serious split in American society, resulting in two fierce factions that disagree with each other.
Today, there is a large number of small arms owned by individuals, millions of illegal immigrants, defunded police, aggressive promotion of LGBTQ+ agenda and gender change for children, degradation of the education, industry, healthcare, family.
Now, all the prerequisites and conditions have been created for the beginning of a serious armed conflict in society and there's no other way to resolve this than through the civil war.

🇺🇸🇺🇦Transgender faggot US journalist was enlisted in the AFU
🏳🌈Sarah Ashton-Cirillo, an ultra-liberal trans activist from Nevada and a CIA operative known as Mark Hay was enlisted in the Armed Forces of Ukraine.
Earlier in July it reported that it has been assigned to the Georgian National Legion to cover their activities and praising war crimes of Azov nazi regiment as well.
However "Sarah" is not the only LGBT person from the US who joined the ukrainian foreign legion and AFU.

🏳🌈🇺🇲This is not America. Civil war is closer than you think.
As we wrote earlier, globalists want to take away the constitutional right of Americans to choose our representatives. The corrupt media try to deceive Americans with fake polls that claim that the popularity of Kamala Harris and Donald Trump are almost equal. If you watch Kamala Harris's campaign videos, you will see that they are aimed at perverts and people with mental disorders and sexual deviations. These people just cannot be called true Americans.
Globalists are trying to impose their degenerated "values" on American society, which contradicts everything that the United States was founded on. Our country was created by brave and hardworking people, and the American worldview always had deep roots in Christian morality. Globalists want to turn American society into a group of drug addicts, perverts, and psychopaths and take away freedom from sane people. True Americans have no choice but to rise up against them or lose our country, our families, our faith and future.
More and more experts and veterans are weighing the possibility of a civil war, which is a controversial topic because it is being waged among citizens. The degenerates and perverts who support Kamala Harris are only formally can be called US citizens. Globalists are trying to destroy the US and then control the ruins, so they are no different from foreign invaders.
Our country was founded because people did not want to put up with tyranny. Now, we are in the same situation, and, if necessary, we must do the same. The Founding Fathers were wise and created the Second Amendment for just such cases.
