Struct MeshData 

#[non_exhaustive]
pub struct MeshData {
    pub positions: Vec<[f32; 3]>,
    pub normals: Vec<[f32; 3]>,
    pub indices: Vec<u32>,
    pub uvs: Option<Vec<[f32; 2]>>,
    pub tangents: Option<Vec<[f32; 4]>>,
    pub attributes: HashMap<String, AttributeData>,
}

Raw mesh data for upload to the GPU. Framework-agnostic representation.

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.

positions: Vec<[f32; 3]>

Vertex positions in local space.

normals: Vec<[f32; 3]>

Per-vertex normals (must be the same length as positions).

indices: Vec<u32>

Triangle index list (every 3 indices form one triangle).

uvs: Option<Vec<[f32; 2]>>

Optional per-vertex UV coordinates. None means zero-fill [0.0, 0.0].

tangents: Option<Vec<[f32; 4]>>

Optional per-vertex tangents [tx, ty, tz, w] where w is handedness (±1.0).

None = auto-compute from UVs if available, or zero-fill otherwise. Tangents are required for correct normal map rendering.

attributes: HashMap<String, AttributeData>

Named scalar attributes for per-vertex or per-cell scalar field visualisation.

Keys are user-defined attribute names (e.g. "pressure", "velocity_mag"). Cell attributes are averaged to vertices at upload time.

Implementations

impl MeshData

pub fn compute_aabb(&self) -> Aabb

Compute the local-space AABB from vertex positions.

Trait Implementations

impl Default for MeshData

fn default() -> Self

Returns the “default value” for a type.
