Struct VertexWeights

pub struct VertexWeights {
    pub count: usize,
    pub inputs: InputList,
    pub joint: usize,
    pub vcount: Box<[u32]>,
    pub prim: Box<[i32]>,
    pub extra: Vec<Extra>,
}

Describes the combination of joints and weights used by a skin.

Fields

count: usize

The number of vertices in the base mesh.

inputs: InputList

The InputS elements describe the joints and the attributes to be associated with them.

joint: usize

The index into inputs for the Semantic::Joint input (which must exist).

vcount: Box<[u32]>

Contains a list of integers, each specifying the number of bones associated with one of the influences defined by VertexWeights.

prim: Box<[i32]>

Contains a list of indices that describe which bones and attributes are associated with each vertex. 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 VertexWeights

pub fn new(inputs: Vec<InputS>, vcount: Box<[u32]>, prim: Box<[i32]>) -> Self

Construct a new VertexWeights from a list of inputs. One of the inputs must have Semantic::Joint.

pub fn joint_input(&self) -> &Input

The input with Semantic::Joint.
