Expand description

A node in the node hierarchy. When the node contains skin, all mesh.primitives must contain JOINTS_0 and WEIGHTS_0 attributes. A node can have either a matrix or any combination of translation/rotation/scale (TRS) properties. TRS properties are converted to matrices and postmultiplied in the T * R * S order to compose the transformation matrix; first the scale is applied to the vertices, then the rotation, and then the translation. If none are provided, the transform is the identity. When a node is targeted for animation (referenced by an animation.channel.target), only TRS properties may be present; matrix will not be present.

Fields§

§camera: Option<Index<Camera>>

The index of the camera referenced by this node.

§children: Option<Vec<Index<Node>>>

The indices of this node’s children.

§extensions: Option<Node>

Extension specific data.

§extras: Extras

Optional application specific data.

§matrix: Option<[f32; 16]>

4x4 column-major transformation matrix.

glTF 2.0 specification: When a node is targeted for animation (referenced by an animation.channel.target), only TRS properties may be present; matrix will not be present.

TODO: Ensure that .matrix is set to None or otherwise skipped during serialization, if the node is targeted for animation.

§mesh: Option<Index<Mesh>>

The index of the mesh in this node.

§name: Option<String>

Optional user-defined name for this object.

§rotation: Option<UnitQuaternion>

The node’s unit quaternion rotation in the order (x, y, z, w), where w is the scalar.

§scale: Option<[f32; 3]>

The node’s non-uniform scale.

§translation: Option<[f32; 3]>

The node’s translation.

§skin: Option<Index<Skin>>

The index of the skin referenced by this node.

§weights: Option<Vec<f32>>

The weights of the instantiated Morph Target. Number of elements must match the number of Morph Targets of used mesh.
