Three.js particles load insanely slow? What's causing the slowness and massive cut in FPS? (From 60+ fps to 1-2 fps)

问题

I can't figure out what's slowing down my visualization. Ideally, I would like 60 fps. Not 1 fps or 2 fps.

Here are the repositories. For the first one, inside LeapVis1.2, if you open index.html with Firefox after you download the folder the vis should load. Non-Particles

For the repository that uses particles, open canvas_particles_random.html in Firefox. Particles (Even slower)

回答1:

First of all this is continuation of this question. The reason of its slowness is because your are using CanvasRenderer instead of WebGLRenderer. I guess you've misunderstood me. In three.js there are two objects: Particle - for canvas and ParticleSystem - for webgl. I've never ment to use canvas, because it is very slow in comparison with webgl.
