Wrong visulization when coordinate values are large

[pkulijing]

Large coordinate values are not handled correctly

A cube put at (0, 0) with the camera targeted on it is correctly rendered

After changing its coordinates to large values, its shape is obviously distorted:

After a fast glance of the code, I think the reason is the limit of single-precision floating point. Worldview uses float to render shapes, which can preserve roughly 6~7 decimal digits. Thus in the above case, some dm-level and all cm level information is lost, resulting in the distortion. Data pre-processing is needed for such large values, i.e. use the value after mod calculation instead of the raw values (7018.084 instead of 837018.084).

Try out https://github.com/foxglove/studio. We do some more intelligent math when you are viewing things centered around certain coordinate frames that are far away from others. There’s a chance it may help for your use case.
