|0025692||Community||[OCCT] OCCT:Modeling Algorithms||public||2015-01-08 20:18||2015-05-14 15:32|
|Target Version||[OCCT] 6.9.0||Fixed in Version||[OCCT] 6.9.0|
|Summary||0025692: Boolean operations minor improvement|
|Description||I was profiling boolean operations, and I have noticed, that a significant amount of time spent in IntPolyh_Point constructor. This is because IntPolyh_MaillageAffinage::TriContact creates lots of IntPolyh_Point objects. But these object creations can be moved after the 6 lines of 'if' instructions, reducing significantly the time spent in that constructor.|
Maybe this is specific only for some shape types, but anyway, this is a reasonable change (and very easy, and also can not cause any bugs).
I have attached the patch file.

|0025692: Boolean operations minor improvement
Method IntPolyh_MaillageAffinage::TriContact() improved so that local objects for detailed analysis are not created if algorithm exits by simple conditions checked at the beginning.
