Ray Onion Dome

Initially, I discovered a technique for developing ‘onion’ domes with muqarnas.
 
An onion dome expands to an ‘equator’ and then narrows again. So it is important to stop narrowing the dome and begin adding tiers. I used the two expansion methods I initially developed, ray and crescent. With themI created the two above onion muqarnas domes.
 
I created the onion dome with the Ray expansion method first, seen above on the right. An animation of it can be viewed below.
 
The onion muqarnas dome on the left of the top image uses the Crescent expansion method. Viewed it below.
 
As with the other dome expansion methods discussed concerning traditional muqarnas domes in my previous post, there is a large number of onion muqarnas dome types possible. Consider the diagram below. The Ray and Crescent methods are used above. Seven other methods are indicated of an unknown total possible.
 
The most noteworthy thing about muqarnas is the endless possible variations in form. This is without considering the many ways that diverse muqarnas forms may be combined.
