Struct SkinningMatrices 

pub struct SkinningMatrices {
    pub matrices: Vec<Mat4>,
}

GPU-ready skinning matrices computed from a pose and skeleton.

Each entry is inv_bind_matrix * world_pose_matrix, which transforms a vertex from bind-pose model space to the animated model space.

Fields

matrices: Vec<Mat4>

Implementations

impl SkinningMatrices

pub fn compute(skeleton: &Skeleton, pose: &Pose) -> Self

Compute skinning matrices from a pose.

The matrices are in bone-index order and ready for upload to a GPU uniform buffer (row-major or column-major depending on shader convention).

pub fn len(&self) -> usize

Number of matrices (equals number of bones).

pub fn is_empty(&self) -> bool

pub fn get(&self, id: BoneId) -> Option<Mat4>

Get the skinning matrix for bone id.

pub fn as_flat_slice(&self) -> Vec<f32>

Return a flat slice of f32 values suitable for a GPU buffer. Each Mat4 contributes 16 f32s in column-major order.

pub fn as_arrays(&self) -> Vec<[f32; 16]>

Return the matrices as an array of column-major arrays.

Trait Implementations

impl Clone for SkinningMatrices

fn clone(&self) -> SkinningMatrices

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SkinningMatrices

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
