我试图将一个正方形或矩形分解为大量随机大小的正方形或矩形,以便没有一个重叠。
好吧,当然其他人问过这个问题,我发现的最好的帖子是 如何用较小的正方形/矩形填充正方形?
解决方案似乎是通过装箱或某种树形图。
但我正在寻找的是 Java、Javacript、actionscript 甚至 C 中的实际算法。
提供的代码创建一个kd 树。您可以使用它在矩形上绘制线条,将其分成更小的矩形。获得树后,您可以按如下方式使用它来将区域划分为这些矩形:
代码:
int MAX_HEIGHT = 100;
int MAX_WIDTH = 100;
int NUM_POINTS = 6;
// Generate random list of points
List<Point> pointList = new List<Point>();
Random rand = new Random();
for(int i = 0; i < NUM_POINTS ; i++)
{
pointList.add(new Point(rand.nextInt(MAX_HEIGHT), rand.nextInt(MAX_WIDTH));
}
BinaryTree tree = CreateKDTree(pointList, 0);
// Recursive function for creating a K-D Tree from a list of points
// This tree can be used to draw lines that divide the space up
// into rectangles.
public BinaryTree CreateKDTree(List<Point> pointList, int depth)
{
// Have to create the PointComparator class that just selects the
// specified coordinate and sorts based on that
Coordinate coord= depth % 2 == 0 ? X_COORDINATE : Y_COORDINATE
Collections.sort(pointList, new PointComparator(coord));
int median = pointList.size() / 2;
// unfortunately Java doesn't have a BinaryTree structure so
// you have to create this too
BinaryTree node = new BinaryTree(pointList[median]);
if(pointList.size() == 1) return node;
if(median > 0)
node.left(CreateKDTree(pointList.subList(0, median), depth + 1);
if(median + 1 < subList.size())
node.right(CreateKDTree(pointList.subList(median + 1, subList.size()), depth + 1);
return node;
}
