Three.js颗粒装入出奇的慢？什么是导致FPS缓慢和庞大的切？ （从60 + FPS 1-2 FPS） [英] Three.js particles load insanely slow? What's causing the slowness and massive cut in FPS? (From 60+ fps to 1-2 fps)

问题描述

我无法弄清楚什么是放慢我的可视化。理想情况下，我想60 fps的。不是1 fps或2 fps的。

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

下面是仓库。对于第一个，里面LeapVis1.2，如果你开的index.html用Firefox您下载相应加载的文件夹后。 非颗粒

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

有关使用颗粒，开放canvas_particles_random.html在Firefox仓库。 颗粒（更慢）

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

推荐答案

首先，这是延续了这个<一href="http://stackoverflow.com/questions/15371176/using-david-piegzas-3d-force-directed-graph-for-large-data-visualization-is-to/15386837?noredirect=1#comment22427449_15386837">question.其缓慢的原因是因为你使用的是CanvasRenderer代替WebGLRenderer。我想你误解了我。在three.js有两个对象：粒子 - 帆布和粒子系统 - 对WebGL的。我从来没有彪用帆布，因为它是非常缓慢与WebGL的比较。

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.
