three.js share a geometry for lines and particles

问题

I would like to use one geometry object for some fancy particle animation and display lines between those particles.

geometry = new THREE.Geometry();

particles = new THREE.ParticleSystem(geometry, particleMaterial);
line = new THREE.Line(geometry, lineMaterial, THREE.LinePieces);

Somehow the Line Object is not rendered in the scene, but the particles show up.

回答1:

With WebGLRenderer you can't share geometry in some specific situations. Best option is to do geometry.clone().

Here's the jsfiddle fixed: http://jsfiddle.net/Pk85y/3/
