Struct SkinnedVertex 

pub struct SkinnedVertex {
    pub position: Vec3,
    pub tex_coords: Vec2,
    pub normal: Vec3,
    pub tangent: Vec4,
    pub joint_indices: [u16; 4],
    pub joint_weights: [f32; 4],
    /* private fields */
}

Same 4 fields as Vertex, plus skinning data.

_pad exists purely so this type has no implicit padding: glam::Vec4 is 16-byte aligned (SIMD-backed), which forces this whole struct’s alignment to 16 — without an explicit trailing field to account for the last 8 bytes, the compiler would insert invisible padding there instead, and #[derive(bytemuck::Pod)] correctly refuses to compile a type with any padding it can’t account for byte-for-byte.

Fields

position: Vec3

tex_coords: Vec2

normal: Vec3

tangent: Vec4

joint_indices: [u16; 4]

Up to 4 joint indices this vertex is bound to, paired positionally with joint_weights. u16, not u32 or u8: glTF’s JOINTS_n accessor is spec-limited to UNSIGNED_BYTE/UNSIGNED_SHORT (never UNSIGNED_INT), so u16 already covers every legal glTF skeleton (up to 65535 joints) losslessly, at half the bytes of u32. gltf_loader::load_gltf upconverts u8-sourced JOINTS_0 data.

joint_weights: [f32; 4]

Implementations

impl SkinnedVertex

pub fn new( position: Vec3, tex_coords: Vec2, normal: Vec3, tangent: Vec4, joint_indices: [u16; 4], joint_weights: [f32; 4], ) -> Self

pub fn layout() -> VertexBufferLayout

Occupies locations 0–3 (same meaning as Vertex’s own 0–3) and 8–9 — deliberately skipping 4–7 (reserved for InstanceVertex) so a skinned mesh can still be instanced in one pipeline without either layout changing. WGSL side: all integer vertex formats widen to vec4<u32> regardless of source width, so declare @location(8) joint_indices: vec4<u32> and @location(9) joint_weights: vec4<f32>.
