如何使用three.js从随机点制作3D对象? [英] How to make 3D object from random points using three.js?

问题描述

我生成了 10 个随机点.我想将每个点相互连接起来，并为每个平坦区域获取面孔.所以，它会是很好的 3D 对象，里面有不可见的平面.

I generate 10 random points. I want connect each point to every another and get faces for every flat area. So, it will nice 3D object with invisible flat faces inside.

如何从 10 个随机点的几何图形中制作人脸?

How is it possible to make faces from geometry of 10 random points?

var objects3 = [];
var geometrySpline = new THREE.Geometry();
  for ( var i = 0; i < 10; i ++ ) {                 
      x = Math.floor(Math.random() * (max - min + 1)) + min;
      y = Math.floor(Math.random() * (max - min + 1)) + min;
      z = Math.floor(Math.random() * (max - min + 1)) + min;
      n = new THREE.Vector3( x, y, z );
      objects3.push( n );
   }
   for ( var x = 0; x < (objects3.length); x ++ ) {
       for ( var x2 = 0; x2 < (objects3.length); x2 ++ ) {
            geometrySpline.vertices.push(objects3[ x ]);
            geometrySpline.vertices.push(objects3[ x2 ]);
       }        
   }

推荐答案

THREE.ConvexGeometry  appears to work as   WestLangley suggested
