Hi!
So right now to find the closest point on a line segment I project the
vectors. Then to see if the point is outside the segment I do,
c = C - A
if (c^ = AB^)
{
if (|c| < |AB|) => lies inside segment
else
return B
}
else
return A
Is there a way to do it without a sqrt? the one needed to calculate the
unit vectors?
