Ellipsoid rotation

CesiumJS

Hello,

We are trying to visualize a data set containing ellipsoids, but we need both rotation and tilt to display them accurately. I don't see this in the EllipsoidGraphics API - is this supported in any way in Cesium?

Thanks!
Kevin

If you’re referring to using the Entity API, then the orientation of an ellipsoid is controlled by the orientation of the entity itself.

Sorry I misspoke. The EllipseGeometry API supports rotation, but EllipsoidGeometry does not. We aren't using the Entity API.

Geometry orientation and position (translation and rotation) are both controlled by the 4x4 model matrix:

That's what I was missing - thank you!
