Terrance: Question. (Sorry if itâ€™s a dumb oneâ€¦..) For the section that reads One consequence of the cosine relationship is that the dot product can be used to determine the relative facing of two vectors. Let d be the dot product between two NORMALIZED vectors. Then: v = 1: the two vectors face the exact same direction 0 < v < 1: the two vectors face roughly the same direction v = 0: the two vectors are perpendicular -1 < v < 0: the two vectors face roughly opposite directions v = -1: the two vectors face exactly opposite directions Did you mean to use d instead of v as if to say â€œif (the dot product)d = 1 :then the two vectors face the exact same directionâ€¦..etc Thanks

Question. (Sorry if it’s a dumb one…..)
For the section that reads
One consequence of the cosine relationship is that the dot product can be used to determine the relative facing of two vectors. Let d be the dot product between two NORMALIZED vectors. Then:

v = 1: the two vectors face the exact same direction
0 < v < 1: the two vectors face roughly the same direction
v = 0: the two vectors are perpendicular
-1 < v < 0: the two vectors face roughly opposite directions
v = -1: the two vectors face exactly opposite directions

Did you mean to use d instead of v as if to say
“if (the dot product)d = 1 :then the two vectors face the exact same direction…..etc

If you seek out toddler beds regarding adults under” All departments”, you
may acquire double divan beds that will match your personality in the
budget you have, 8 of the three-inch wood screw’s diameter. Kids can add finishing touches by helping in the bedroom decorating and coloring the Toddler Beds. Were living in very hard economic times, and there are practically no chances of the bed.

Check out the plugin “Mathjax Latex” for wordpress, it will allow you to typset math nicely with latex using some js post-processing. Get it “post” processing 😉

Eg. $$v_x = \|\vec{v}\|\sin\theta$$ or the other style $\cos\theta$ for inline math,
and \[ \sin^2\theta + \cos^2\theta = 1\] for display style.

[…] This is the long due fifth article in this series. If you aren’t comfortable with vectors, you might want to take a look at the first four articles in this series before: Introduction, Vectors 101, Geometrical Representation of Vectors, Operations on Vectors. […]

Interesting article, though I’m not a game developer myself, I do love the mathematics behind most programming subject ^^
