> what shape is it, oh, it's a circle, so now check what I am colliding with While this is true, consider that the huge library of built-up optimizations in a well used collision library like Havok very likely makes up for these checks. Alternatively, they generally offer a lower level API such that you could just always call: `Havok::CheckCircleAAPlane` and then not have to worry about Havok doing it's dispatch. But then again if you don't use Havok's spatial culling you're likely missing out on a whole lot of optimizations, and advantages to using Havok.
