Struct MeshItem 

pub struct MeshItem {
    pub points: PointVec<DVec3>,
    pub triangle_indices: Vec<u32>,
    pub vertex_colors: PointVec<Rgba>,
    pub vertex_normals: PointVec<DVec3>,
}

A high-level mesh item with per-vertex data wrapped in PointVec for animation support.

This struct uses PointVec to wrap vertex data, enabling proper alignment and interpolation for animations. When extracted, it converts to the low-level ranim_core::core_item::mesh_item::MeshItem for rendering.

The vertices are expressed in the mesh’s local space. To place or animate the mesh with an external transform, wrap it in ranim_core::core_item::transformed::Transformed, commonly storing [ranim_core::glam::DAffine3] as the transform representation.

Fields

points: PointVec<DVec3>

The vertices of the mesh (local space)

triangle_indices: Vec<u32>

The triangle indices

vertex_colors: PointVec<Rgba>

Per-vertex colors

vertex_normals: PointVec<DVec3>

Per-vertex normals for smooth shading. All-zero (or empty) → shader falls back to flat shading via dpdx/dpdy.
