line.divideAt(t)
Divide the line into two lines at the point that lies t
(normalized length) away from the beginning of the line.
Returns an array with two new lines without modifying the original line. For example, if t
equals 0.5
, the function returns an array of two lines that subdivide the original line at its midpoint.
The function expects t
to lie between 0 and 1; values outside the range are constrained to 0 and 1, respectively.
