• @PanicsAtCaller Public New(point: Func(Float): Vec3, samples: Int = 256) constructor #

  The curve point gives for t from 0 to 1, measured at samples places along it. Fewer than one sample panics.

• @PanicsAtCaller Public Static Method CatmullRom(points: Vec3[], closed: Bool = False, samples: Int = 64): Curve3 static method #

  The Catmull-Rom spline through the points, each of them on it, around to the first when closed, measured at samples places along each segment. Fewer than two points, or than one sample, panics.

• @PanicsAtCaller Public Static Method BSpline(points: Vec3[], closed: Bool = False, samples: Int = 64): Curve3 static method #

  The uniform cubic B-spline the points shape, near them rather than through them: an open one starts and ends at its ends, and a closed one goes around. It's measured at samples places along each segment. Fewer than two points, or than one sample, panics.

• @PanicsAtCaller Public Static Method Bezier(points: Vec3[], samples: Int = 64): Curve3 static method #

  The cubic Beziers one after another, each from the last one's end: a start, then two control points and an end for each, so 3n + 1 points in all, measured at samples places along each. Any other count of points, or fewer than one sample, panics.

• Public Property Length: Float property #

  How long the curve is, as its samples measure it.

• @PanicsAtCaller Public Method PointAt(t: Float): Vec3 method #

  The point the curve's Function gives for t, kept from 0 to 1. A NaN t panics.

• @PanicsAtCaller Public Method PointAtDistance(distance: Float): Vec3 method #

  The point so far along the curve, kept from 0 to its Length. A NaN distance panics.

• @PanicsAtCaller Public Method Sample(count: Int): Vec3[] method #

  count points along the curve the same distance apart, from its start to its end. Fewer than two panics.
