Abstract:
1. A system comprising: one or more processors; a memory having instructions stored thereon that, if executed by the one or more processors, cause the one or more processors to perform operations comprising: accessing data representing at least a portion of a parametric curve; identifying a subdivision point along the at least a portion of the parametric curve such that when two linear segments are defined that connect the subdivision point to respective endpoints of the at least a portion of the parametric curve, a maximum chord error on each side of the subdivision point is equal, wherein the maximum chord error is a maximum distance between each of the two linear segments and respective points on two sub-portions of the at least a portion of the parametric curve between the respective endpoints and the subdivision point; storing data indicative of the subdivision point; determining whether the maximum chord error exceeds a pre-determined error tolerance; and in response to determining that the maximum chord error exceeds the pre-determined error tolerance:
