Method Details

isSinglePoint

public boolean isSinglePoint()

containsPoint

public boolean containsPoint(BezierPoint point)

updateCoeffs

public void updateCoeffs()

Updates the cubic Bézier coefficients. Only recalculates if the spline is not a single point.

lerp

public net.minecraft.world.phys.Vec3 lerp(double t)

Interpolates a position on the spline at parameter t (0 to 1). Uses cubic Bézier curve formula: B(t) = (1-t)³P0 + 3(1-t)²tP1 + 3(1-t)t²P2 + t³P3

derivative

public net.minecraft.world.phys.Vec3 derivative(double t)

Gets the derivative (tangent) of the spline at parameter t. Used for calculating arc length and velocity.

getLength

public double getLength()

Calculates the approximate length of the spline segment.
