V3.direction(a, b, r)
the original direction function returned the direction from b to a, instead of a to b as stated in the comment.
Function: V3.direction
Perform
r = (a - b) / |a - b|. The result is the normalized
direction from a to b.
Parameters:
a - the first vector operand
b - the second vector operand
r - optional vector to store the result in
Returns:
If r is specified, returns r after performing the operation.
Otherwise, returns a new 3-element vector with the result.
- Parameters:
- a
- b
- r
