Struct gltf_json::scene::Node

pub struct Node {
    pub camera: Option<Index<Camera>>,
    pub children: Option<Vec<Index<Node>>>,
    pub extensions: Node,
    pub extras: Extras,
    pub matrix: [f32; 16],
    pub mesh: Option<Index<Mesh>>,
    pub rotation: UnitQuaternion,
    pub scale: [f32; 3],
    pub translation: [f32; 3],
    pub skin: Option<Index<Skin>>,
    pub weights: Option<Vec<f32>>,
}

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: Node

Extension specific data.

extras: Extras

Optional application specific data.

matrix: [f32; 16]

4x4 column-major transformation matrix.

mesh: Option<Index<Mesh>>

The index of the mesh in this node.

rotation: UnitQuaternion

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

scale: [f32; 3]

The node's non-uniform scale.

translation: [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.

Trait Implementations

impl Clone for Node

fn clone(&self) -> Node

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Node

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Validate for Node

fn validate_minimally<P, R>(&self, _root: &Root, _path: P, _report: &mut R) where
    P: Fn() -> Path,
    R: FnMut(&Fn() -> Path, Error), 

Validates only the invariants required for the library to function safely.

fn validate_completely<P, R>(&self, _root: &Root, _path: P, _report: &mut R) where
    P: Fn() -> Path,
    R: FnMut(&Fn() -> Path, Error), 

Validates the data against the glTF 2.0 specification.
