curve.divideAtT(t)
Divide the curve into two curves at the point specified by t
.
Returns an array with two new curves without modifying the original curve. The function expects t
to lie between 0 and 1; values outside the range are constrained to 0 and 1, respectively.
This function is not a counterpart to the line.divideAt()
function. The relationship between t
and distance along a curve is complex and non-linear. If it is necessary to divide the curve at a certain ratio
(normalized length) away from beginning of the curve, use the curve.divideAt()
function.
