API Reference > geometry-core > CartesianGeometry > Segment1d > clipBy01FunctionValuesPositive clipBy01FunctionValuesPositive Method On input, this is an interval of a line. On output, the interval has been clipped to positive parts of a linear function f0 and f1 are values at parameter values 0 and 1 (which are in general NOT x0 and x1) From that determine where the segment crosses function value 0. The segment contains some interval in the same parameter space. Clip the segment to the positive part of the space. Return true (and modify the segment) if any of the segment remains. Return false (but without modifying the segment) if the active part is entirely out. clipBy01FunctionValuesPositive(f0: number, f1: number): boolean Parameter Type Description f0 number f1 number Returns - boolean Defined in geometry3d/Segment1d.ts Line 125 Last Updated: 11 June, 2024
