Struct FbxMeshInstance 

pub struct FbxMeshInstance {
    pub name: Option<String>,
    pub mesh: Mesh,
    pub control_points: Vec<[f32; 3]>,
    pub polygon_vertex_indices: Vec<i32>,
    pub layers: FbxMeshLayers,
    pub edges: Vec<i32>,

    pub skin: Option<FbxSkin>,
    pub morph_targets: Vec<FbxMorphTarget>,
}

Available on crate features fbx-reader or fbx-writer only.

Geometry attached to one FbxSceneNode.

This is materialized Draco geometry, not a lossless FBX geometry object.

Fields

name: Option<String>

Name supplied by the FBX geometry node, when available.

mesh: Mesh

Decoded mesh geometry.

control_points: Vec<[f32; 3]>

Original FBX control-point positions, retained independently from the resolved render mesh used by Draco/WebGL.

polygon_vertex_indices: Vec<i32>

Original FBX polygon-corner indices. Negative values terminate a face.

layers: FbxMeshLayers

Layer elements preserved from the source geometry node.

edges: Vec<i32>

Original FBX Edges array, verbatim.

Each entry indexes Self::polygon_vertex_indices, naming the polygon corner an edge starts at. FBX does not require this to list every topological edge – importers reconstruct the missing ones from faces – so it is kept raw rather than normalized. It is also the domain ByEdge layer elements address.

material_indices: Vec<i32>

Per-polygon material index from LayerElementMaterial, when present.

Each entry corresponds to one triangle in fan-triangulation order produced by crate::FbxReader. Entries are absolute indices into FbxScene::materials. The list is empty when the geometry does not carry a material layer (callers fall back to the first material).

skin: Option<FbxSkin>

Skin binding for this geometry, when it is armature-deformed.

morph_targets: Vec<FbxMorphTarget>

Blend-shape targets defined for this geometry.

Implementations

impl FbxMeshInstance

pub fn to_render_mesh(&self) -> FbxRenderMesh

Expands this instance onto the polygon-corner domain.

pub fn to_draco_mesh(&self) -> Mesh

Corner-domain Draco mesh for this instance, welded by attribute tuple.

Falls back to the stored mesh when the instance carries no raw FBX geometry to expand.

Trait Implementations

impl Clone for FbxMeshInstance

fn clone(&self) -> FbxMeshInstance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FbxMeshInstance

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

Formats the value using the given formatter.

impl Default for FbxMeshInstance

fn default() -> FbxMeshInstance

Returns the “default value” for a type.
