    Type Alias ConeConstraint

    ConeConstraint: ConstraintBase & {
        angleConstraintPart: AngleConstraintPart;
        cosHalfConeAngle: number;
        cosTheta: number;
        localSpacePosition1: Vec3;
        localSpacePosition2: Vec3;
        localSpaceTwistAxis1: Vec3;
        localSpaceTwistAxis2: Vec3;
        pointConstraintPart: PointConstraintPart;
        worldSpaceRotationAxis: Vec3;
    }

    Cone constraint constrains 2 bodies to a single point and limits the swing between twist axes within a cone.

    Constraint: t1 · t2 >= cos(θ)

    Where:

    • t1 = twist axis of body 1 (world space)
    • t2 = twist axis of body 2 (world space)
    • θ = half cone angle (angle from principal axis of cone to edge)

    This removes 3 translation DOF (point constraint) and limits rotation to a cone (1 DOF limit). Note: Unlike SwingTwistConstraint, this does NOT constrain twist rotation around the axis.

    Type Declaration

    • angleConstraintPart: AngleConstraintPart

      angle constraint for cone limit (1 DOF)

    • cosHalfConeAngle: number
