Re: Compare TGeoShape

Hi Jason,

This comparison is not implemented and not in the plan. The reason is that there are ~20 different shapes and this makes the implementation effort too big and not scaling with the limited use cases. Besides, this cannot be implemented for Boolean composite shapes that can be of infinite variety.

Best,
Andrei
