I suppose the benefit of having a specially-designed Vector .pyd for Poser Python would really be accessibility.  I don't know whether Numeric can be as fast as or faster than what Spanki is doing, because I don't understand Numeric.  The docs for the module are unclear and perplexing, as are any examples I've seen.  A tool is less useful if no one understands how to use it effectively, unfortunately.  How many Poser Python users use Numeric?  How many understand how to use it effectively?  A more straightforward tool would be a true boon for PPy, IMO.

So, no, we're not using Numeric at all effectively.  :(

In the meantime, I'm trying to read up on it again.  In the examples I've seen, it looks like Numeric's internal tools can only handle some of the needs of matrix handling.  Some functions, like inverting a matrix, were approached using the Linear Algebra module, which, as I said, is broken in P7.  It doesn't seem like Numeric or the other modules provided with Poser's build of Python really offer a full (much less accessible) toolset for 3D math.  Kind of a bummer, if that's actually the case....

(Mild irony alert: TDMT may or may not be a tool, itself, which no one really understands how to use, aside from the programmers....)

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
