Hey guys, There’s a to-scale Solar System project that I’m working on which is using real data scraped from NASA’s website. Due to this there’s some massive scale differences when switching between planets and moons. Each entity also comes with its own orbit line, and depending on an entity’s orbi…

Could be you’re running out of precision in the shader code, when you’re looking at the very tiny piece of your system due to the large scale of it. You might be looking at numerical errors of calculating vertices positions.

Thanks. I’ve done some looking around, and it looks like this problem is not uncommon. [Zob] Can I Increase Vector Precision in THREE.js? three.js, precision, shake, largenumber asked by Zob on 09:44AM - 28 Oct 14 UTC

I don’t think the problem here is THREE.js or JavaScript numeric precision. Ultimately, you upload your numbers on the GPU to calculate in the shader, and the shader precision (at least for WebGL) is quite low, that’s the bottleneck. Logarithmic Z-buffer is not a magic trick to increase overall num…

Hi, Jollus. I’m trouble in the same issue:( [image] lineMaterial wobbles/shakes when zooming in on small object Questions Dear all, I am currently creating a solar system example with three.js, as many users have done. However, when I set up the size of the orbit in real…

The only resolution, so far, is to use smaller numbers. This may require extremely large scenes to be split into chunks, each having own coordinate system. GPU floating point numbers are short (24 or 32 bits only) and they have inherent limited precision, much less than the precision in JavaScript …
