我在画布上画了一堆粒子。我使用以下代码:
var geometry = new THREE.Geometry();
nodeSet.forEach(function (value, index) {
if (value.Name.indexOf("p(") == "0") {
particle = new THREE.Particle(protien);
} else { particle = new THREE.Particle(material); }
particle.ID = value.ID;
particle.position.x = value.Xpos;// Math.random() * 2 - 1;
particle.position.y = value.YPos; //Math.random() * 2 - 1;
particle.position.z = Math.random() * 2 - 1;
particle.position.normalize();
particle.position.multiplyScalar(Math.random() * 10 + 450);
particle.scale.x = particle.scale.y = 5;
scene.add(particle);
geometry.vertices.push(particle.position);
});
现在,我想绘制一条基于particle.ID连接两个粒子的线。有人可以帮助并指出我如何做到这一点的方向?
