Can anyone suggest a good c++ date (or date/time) class implementation?

Hard mode: don't use the word "boost"

So when you said some of your polygons were clockwise and some were anti-spinward counterclockwise, I'm wondering: Is there a reason for that?

Yeah, it's a data-entry thing. These polygons are data imported from Tiled and used for collision mapping. I'm getting the Minkowski Sum of an (arbitrarily-sized) AABB and a completely arbitrary polygon pulled from the collision map, so that I can perform predictive collision testing.

So I need to find the minkowski sum of two arbitrary polygons. According to some articles I've read about the subject, I need to merge the list of vertices in the two polygons into one, while maintaining the ordering by angle. The resulting polygon has to be convex, so they have to be sorted by the ϴ (angle) portion of their polar coordinates.

This might be pretty easy if these lists of vertices started at the rightmost point and worked around counter-clockwise, but they start at arbitrary positions and can go clockwise too. This might take a while.

Are you planning on individually generating all those stars?

My dad just died in a car accident, my life is a fucking mess, we're probably going to lose our house, and this is literally the only place I could think of to talk about it because I hardly have any friends left.

And now we all post the song we wish got used in a flash, but never did.

I'm not even sure PASSTHROUGH is a keyword. It's just an alias for the returned query results or something. Anyway, I can always just perform another query on the results... but you'd think sql would give you every filtering option available to decrease bandwidth.

If you're learning c++, do yourself a favor and learn how static and dynamic libraries work as soon as possible.
