Struct Skin

pub struct Skin {
    pub source: UrlRef<Mesh>,
    pub bind_shape_matrix: Option<Box<[f32; 16]>>,
    pub sources: Vec<Source>,
    pub joints: Joints,
    pub weights: VertexWeights,
    pub extra: Vec<Extra>,
}

Contains vertex and primitive information sufficient to describe blend-weight skinning.

Fields

source: UrlRef<Mesh>

A URI reference to the base mesh (a static mesh or a morphed mesh). This also provides the bind-shape of the skinned mesh.

bind_shape_matrix: Option<Box<[f32; 16]>>

Provides extra information about the position and orientation of the base mesh before binding. Contains sixteen floating-point numbers representing a four-by- four matrix in column-major order. If bind_shape_matrix is not specified then an identity matrix may be used as the bind_shape_matrix.

sources: Vec<Source>

Provides most of the data required for skinning the given base mesh.

joints: Joints

Aggregates the per-joint information needed for this skin.

weights: VertexWeights

Describes a per-vertex combination of joints and weights used in this skin. An index of –1 into the array of joints refers to the bind shape. Weights should be normalized before use.

extra: Vec<Extra>

Provides arbitrary additional information about this element.

Implementations

impl Skin

pub fn new( source: Url, sources: Vec<Source>, joints: Vec<Input>, weights: VertexWeights, ) -> Self

Construct a Skin from the mandatory data.

• The source should reference a Mesh.
• There should be at least 3 sources.
• One of the joints must have Semantic::Joint.

Trait Implementations
