Facing vector?

Recommended Posts

Sevans    204
Can anyone explain to me what a facing vector is, possibly with a small example. Math jargon explainations never seem to help :). I am not sure if this will help explain it at all, but before any rotations the "front" of the object points in the +z direc, the right of the object points to the -x direc, and the object thinks +y is up. Thanks much, -sevans

Then at start your forward vecotr would be +z. As your object was rotated, the forward vector would be transformed by the same rotations.

So my facing vector is
x y z
{ 0, 0, 1 }

??
'Facing vector' isn't a formal term per se, but I'm guessing in this context it's synonymous with 'forward vector'. So assuming +z is forward, your example above is correct.
