Joint QML Type▲

Import Statement: import QtQuick3D
Inherits: Node

Detailed Description▲

A joint is a transformable node inside a Skeleton, used for skeletal animation. It is called a "joint" because it can be seen as a joint between the bones of a skeleton.

All the joints must be contained inside a Skeleton, and each joint must have a skeletonRoot pointing back to that skeleton.

Sélectionnez

Skeleton {
    id: qmlskeleton
    Joint {
        id: joint0
        index: 0
        skeletonRoot: qmlskeleton
        Joint {
            id: joint1
            index: 1
            skeletonRoot: qmlskeleton
        }
    }
}

Property Documentation▲

index : int▲

Specifies the index of this joint. This index value is used in the JointSemantic custom geometry attribute.

Index values must be unique within the same Skeleton.

Negative values cannot be assigned.

skeletonRoot : Skeleton▲

Specifies the Skeleton that contains this joint.

All the Joints in the Skeleton must have the same skeletonRoot. If not, the animation will be broken.
