Summary 0026957: Unify same domain operation is slow for multiple shells
Revision 2015-12-05 22:07 by abv
Description DRAW command unifysamedom works several times slower for shape consisting of 6 shells than for the same shape where all faces are collected in one shell. Besides, the result in the first case contains 6 shells and only one face (5 of shells are empty).

The problem was detected by comparing performance of test demo samples snowflake in OCCT 6.9.1 and 7.0.0.dev: the argument of unifysamedom command in this test is generated by Boolean operations, and due to changes in how they work with shells, its structure has changed.

Note that behavior is the same in OCCT 6.9.1
