Methods of transferring data while copying shells.

Methods of transferring data while copying shells in operations on solids.
Any operation (successful or faulty) modifies vertices, edges and shell faces of operands irreversibly.
Used full or partial copying of data to save the initial operand shell.
Four methods of transferring data to operation are used.
If it is not required to save the data, then the shell isn't copied and the original shell is used.
If it is required that the operation should not spoil the original shell and save memory, then the base surfaces and vertices are saved in a copy of the shell. In addition after operation a copy and the initial shell have common faces unchanged by operation.
If it is required that the operation should not spoil the original shell and had a high speed, then the base surfaces and vertices are saved in a copy of the shell.
If it is required that the operation result should not relate to the original objects, then the vertices, edges, surfaces and faces of operands are copied. This approach is used in operations which transform solid, such as mirroring.
