General Surface API mapping
Created by: portnov
In this issue I will try to outline a general API for all types of surface we are going to support.
Legend:
-
🆕 there is no such method in the base class yet, it has to be introduced to support features provided by one (or several) of backends. -
🚧 this method can and must be implemented in the base class by means by other (more basic) methods - there is a not-so-hard to implement numeric algorihtm -
❌ this method can not be implemented if the backend library does not support it (or it is too hard to implement it) -
❓ probably possible to implement without backend support, requires further investigatio
