== Unit research == | |||
For the purposes of this comment, I will define the following suffixes: | |||
;'''hk''' | |||
: Havok units | |||
;'''wu''' | |||
: World units | |||
Assume that existing unit suffixes (m, in, etc.) are also in play. | |||
As far as I am aware, 1hk = 69.99125wu. I got curious as to why ''that'' is the conversion factor, so I started digging into unit relationships. | |||
Here are my findings based, initially, on random guesses, and then on pulling at the thread I found: | |||
{| class="wikitable" | |||
|+ Unit relationships | |||
|- | |||
! A !! u !! = !! B !! u !! Comment | |||
|- | |||
|  1 || hk || = || 69.99125 || wu | |||
|- | |||
|  0.0142875 || hk || = || 1 || wu || The Havok value is just 1 ÷ 69.99125 | |||
|- | |||
| 64 || m || = || 69.99125 || yd || Hm. Isn't that a neat coincidence? | |||
|- | |||
|  1 || m || = ||  1.09361328125 || yd | |||
|- | |||
|  0.9144 || m || = ||  1 || yd | |||
|- | |||
|  0.9144 || m || = || 36 || in | |||
|- | |||
|  0.0142875 || m || = ||  0.5625 || in | |||
|} | |||
I checked the original article afterward, and this matches the table in the article, which in turn is based on the [[Glossary]]'s entry for [[Glossary#Exterior Cells|Exterior Cells]]. The conversion factor listed there comes from the article's original revision, by a Bethesda employee. Exterior cells are 4096x4096, which (per both the table in the article and the table above) works out to 2304x2304in or 192x192ft. | |||
Let's continue our table, though: | |||
{| class="wikitable" | |||
|+ Unit relationships | |||
|- | |||
! A !! u !! = !! B !! u !! Comment | |||
|- | |||
| 4096 || wu || = ||  32 || vertices || Exterior cells' heightmapped terrain is a 32x32-vertex grid. | |||
|- | |||
|  192 || ft || = ||  32 || vertices | |||
|- | |||
|  128 || wu || = ||   1 || vertex | |||
|- | |||
|    6 || ft || = ||   1 || vertex | |||
|} | |||
My guess is that Bethesda wanted 128wu to equal 6ft. ''That's'' the rationale for Skyrim's world units, and everything else — the strange Havok conversion factor included — fell out from that. | |||
