The Vector3D class debuted in Flash Player 10.0 as Adobe’s official implementation of, well, a 3D mathematical vector (not the pseudo-Array class Vector). Weirdly, it has a w component and is therefore technically a 4D vector, but its API inconsistently make use of the fourth dimension. There are also strange oversights, inefficiencies, and functionality it really should have always had. Read on for my custom Vector3D derivative—Vector3DExt—that fixes all of these problems by extending and improving on the original.

I was reminded about the flash.sampler API by Grant Skinner’s recent post about it. While only available in the debug player, it can still tell us some valuable information about what goes on in the release player. Today I’m using the getSize function to find out how much memory overhead various classes impose, even when they are empty.
