在形状内聚类元素

Question

我已经看到这个解决方案似乎在没有重叠的情况下处理"一致"形状内的聚类元素,但是如果形状更加模糊,如下所示:

我的第一对夫妇似乎指向将形状简化为最基本的形式,然后执行检查元素是否在实际形状坐标内,但这似乎是我希望简化的大量潜在计算.任何想法都会非常感激.谢谢!

JS小提琴参考:

var tilesize = 18, tilecount = 15;
var gRows = Math.floor($(".container").innerWidth()/tilesize);
var gCols = Math.floor($('.container').innerHeight()/tilesize);

var vals = _.shuffle(_.range(tilecount));
var xpos = _.shuffle(_.range(gRows));
var ypos = _.shuffle(_.range(gCols));

_.each(vals, function(d,i){
    var $newdiv = $('<div/>').addClass("tile");
    $newdiv.css({
        'position':'absolute',
        'left':(xpos[i] * tilesize)+'px',
        'top':(ypos[i] * tilesize)+'px'
    }).appendTo( '.container' ).html(d);  
});

编辑

这个例子在一个定义的形状中有随机聚类,但由于那个形状的上下文不是正方形,我需要做一些测试,首先将SVG对象转换为canvas元素,然后通过类似的东西运行代码.

尝试创建图像的ASCII表示,css white-space设定为pre,.html(),String.prototype.replace()与RegExp以匹配串的任何字符,在输入字符串中返回元件作为替代匹配字符html

$(function() {
  $("div").html(function(index, html) {
    return html.replace(/g/g, function(match) {
      return "<span>" + match + "</span>"
    })
  })
})

div {
  font: 8px/4px monospace; 
  text-align: center;
  white-space:pre;
}

span {
  background-color:dodgerblue;
  color: navy;
  text-shadow: 0.75em 0.75em gold;
}
