API Reference › core-geometry› Solid › Sphere › StrokeConstantVSection

strokeConstantVSection Method

Return strokes for the elliptical arc cross-section at latitude sweep fraction v.

  • Optional inputs control the number of strokes along the cross-section:
    • If fixedStrokeCount is supplied, it is taken as the cross-section stroke count.
    • If fixedStrokeCount is undefined, stroke count is computed by applying options to the cross-section.
    • If neither input is supplied, the stroke count default is 16.
    • In any case, stroke count is clamped to the interval [4,64].
