KML error with non-earth ellipsoid #6176

Now that is a clever hack ... er ... workaround! Thanks!

If you find any more issues, let us know!
As a workaround, setting Cesium.Ellipsoid.WGS84 = new Cesium.Ellipsoid(x,
y, z) should fix most problems

For the record, making that change does not correct this issue ... |

Ah yeah. We had to do that because the If you have time, we'd be happy to review a PR with the KML fix! |

Thanks guys! I just pushed some code in my fork to fix it -- I will do a
little testing and then a pull request.
WHILE YOU ARE LOOKING AT THIS, @mramato, what I'm really working on is
polar stereographic projection on the moon:

I know this is off topic but if you have a chance to make suggestions that
would be very helpful. Once I solve this I would love to contribute it.
I've done what I thought was the "hard part", namely the projecting
to/from, but the bounds of my tiles are drawing in the wrong place.
Thanks! I'm having so much fun with Cesium.

p.s. and my fix does not refactor your dependency on
Cartesian3.fromDegrees, just passes along the ellipsoid.

But now that I'm here, that's definitely a bug (KmlDataSource should not
be using Cartesian3.fromDegrees, or any of our internal code for that
matter). We have those hardcoded values purely because it lets us provide
that helper function for end users, but internally it's a no go.

Are there instructions somewhere for doing a development npm build?
Doing this (from my fork):
npm install git+https://[email protected]/xgds/cesium.git
completely broke my webpack process, which works when I use the regularly
released npm cesium.
Thanks

Hi @tamarmot, we just pushed an npm fix about half an hour ago - https://www.npmjs.com/package/cesium I'm running the build right now with our recommended webpack configuration to see if that is working. |

Thanks Gabby!

Sorry -- that didn't answer my question -- is there documentation for how I
can take my fork and npm-ify it so I can test it in my environment before I
do a pull request?
Thanks
Tamar

I am loading some KML to render on my moon ellipsoid. When I look at the coordinate conversion in KmlDataSource, I see that it is not using any ellipsoid to calculate the coordinates.
For example, with:
longitude: 24.070617695061806
latitude:87.90173269295278
I get coordinates:
Cartesian3 {x: 213935.5635247161, y: 95566.36983235707, z: 6352461.425213023}
instead of lunar coordinates:
Cartesian3 {x: 58080.7702560248, y: 25945.04756005268, z: 1736235.0758562544}
I suggest the constructor for a KmlDataSource takes an option for an ellipsoid, which is then used for every single Cartesian3.fromDegrees call.
