Compare Smoothing Groups
Hi all, hopefully an easy one here...
-- The short --
I'm looking to compare two polygons' smoothing groups, received as "bitwise integers" (eg. 12 = '001100'… = smoothing groups 3 and 4... and 5 = '101000' = smoothing groups 1 and 3) to see if they have any activated bits in common. Any ideas how to do this?
-- The Long -- (if the above wasnt enough info)
I'm trying to make a script which selects all "hard edges" (an edge where its face-neighbours do not share a smoothing group). I'm stuck on the "share a smoothing group" part...
So I've successfully got two faces' smoothing groups (using polyOp.getFaceSmoothGroup), which returns, from what ive read a "bitwise integer" eg. 001001… = smoothing groups 3 and 6
But I'm not sure how to compare these bitwise integers...
So I guess I'm looking for a way of writing function "SharesSG" in this:
Face1SGs = polyOp.getFaceSmoothGroup(someObject 1) Face2SGs = polyOp.getFaceSmoothGroup(someObject 2) if SharesSGs(Face1SGs, Face2SGs) == true do -- ... blah
Many thanks in advance for your time
