## [4、点阵特效](点阵特效.py)
|
||||
|
||||
1. emmm,我也不知道这个动画叫啥名字,反正就是仿照网页做的
|
||||
1. 参考js源码,大概的原理就是:
|
||||
1. 先根据窗口大小随机创建一些点
|
||||
1. 遍历这些点找到跟它自己关联的点
|
||||
1. 动画开始画圆点、画连线
|
||||
1. 动画改变这些点的透明度, 用到了属性动画`QPropertyAnimation`
|
||||
1. 这里没有仔细去研究js里的算法优化,在浏览器里嗖嗖的就生成了,在py里好慢....
|
||||
1. 尽量在py里优化了循环操作,也简单的做了个cython加速也才提高了1s ? 1倍?...
|
||||
1. 不要为了xx用这玩意儿,和网页的效果一样,占CPU !!!!!!
|
||||
1. 如果有更好的优化算法请告知, 3Q
|
||||
1. PS: pyd是python3.4生成的,删掉pyd也能运行
|
||||
|
||||
这部分是js的核心
|
||||
```js
|
||||
// for each point find the 5 closest points
|
||||
for(var i = 0; i < points.length; i++) {
|
||||
var closest = [];
|
||||
var p1 = points[i];
|
||||
for(var j = 0; j < points.length; j++) {
|
||||
var p2 = points[j]
|
||||
if(!(p1 == p2)) {
|
||||
var placed = false;
|
||||
for(var k = 0; k < 5; k++) {
|
||||
if(!placed) {
|
||||
if(closest[k] == undefined) {
|
||||
closest[k] = p2;
|
||||
placed = true;
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
for(var k = 0; k < 5; k++) {
|
||||
if(!placed) {
|
||||
if(getDistance(p1, p2) < getDistance(p1, closest[k])) {
|
||||
closest[k] = p2;
|
||||
placed = true;
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
p1.closest = closest;
|
||||
}
|
||||
```
|
||||
|
||||
这部分是py的核心
|
||||
```python
|
||||
def findClose(points):
|
||||
plen = len(points)
|
||||
for i in range(plen):
|
||||
closest = [None, None, None, None, None]
|
||||
p1 = points[i]
|
||||
for j in range(plen):
|
||||
p2 = points[j]
|
||||
dte1 = getDistance(p1, p2)
|
||||
if p1 != p2:
|
||||
placed = False
|
||||
for k in range(5):
|
||||
if not placed:
|
||||
if not closest[k]:
|
||||
closest[k] = p2
|
||||
placed = True
|
||||
for k in range(5):
|
||||
if not placed:
|
||||
if dte1 < getDistance(p1, closest[k]):
|
||||
closest[k] = p2
|
||||
placed = True
|
||||
p1.closest = closest
