1. A concise explanation of the problem you're experiencing.
ThreeJS has an applyQuaternion on a vector to achieve a rotation of the vector. So a circle can be created for example by rotating the unit vector around an axis with vector.applyQuaternion()
Is there an way to do this in Cesium with Cartesian3 and Quaternion?
2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.
step is a quaternion defined like this:
step.setFromAxisAngle(new Three.Vector3(0, 1, 0),
Three.Math.degToRad(360 / tesselation));
for the number of steps around the circle:
3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
I want to collect the vertices of a circle for example.
I'd like to use quaternions if possible for flexibility.
4. The Cesium version you're using, your operating system and browser.
