Vector Angle Error

[Martin]

Hi,

If I check the Angle between two (almost) identical vectors with reversed Direction I get a math Domain Error.

I attached a Screenshot.

Thanks.

Hi Martin,
I see the bug. It think this will be fixed in the next WIP (I believe I got the fix in before the weekly automated build started.) I needed to clamp the dot product between -1 and 1. If there was any "fuzz" in the calculation which resulted in something like -1.00000000001, then acos would raise this exception.

If this isn't fixed in the next WIP, I'll get you the updated scripts through googlecode.
Thanks,
-Steve
