Struct PrimitiveMeasurements 

#[non_exhaustive]
pub struct PrimitiveMeasurements {
    pub primitive_index: usize,
    pub material_index: Option<usize>,
    pub vertex_count: u64,
    pub finite_vertex_count: u64,
    pub geometry_aabb: Option<Aabb>,
    pub geometry_centroid: Option<[f32; 3]>,
}

Static base-geometry measurements of one source mesh primitive.

Position rows are measured exactly as decoded by the loader. Indexed primitives therefore count each stored position once, rather than counting index references.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

primitive_index: usize

Zero-based position in the owning mesh’s source primitive array, or retained primitive order when the normalized document has no source primitive identity.

material_index: Option<usize>

Stable source material index, when the primitive declares one.

vertex_count: u64

Number of decoded base POSITION rows, including non-finite rows.

finite_vertex_count: u64

Number of decoded base POSITION rows whose coordinates are finite.

geometry_aabb: Option<Aabb>

Bounding box over finite base POSITION rows.

geometry_centroid: Option<[f32; 3]>

Arithmetic mean of finite base POSITION rows.
