Definition from ISO/CD 10303-42:1992: A polyline is a bounded curve of n - 1 linear segments, defined by a list of n points, P1, P2 … Pn. The ith segment of the curve is parameterized as follows:
for 1 ≤ i ≤ n - 1
where i - 1 ≤ u ≤ i and with parametric range of 0 <≤ u ≤ n - 1.
NOTE Corresponding ISO 10303 entity: polyline. Please refer to ISO/IS 10303-42:1994, p. 45 for the final definition of the formal standard.
