Struct FbxGeometryLayers 

pub struct FbxGeometryLayers<'a> {
    pub control_points: &'a [[f32; 3]],
    pub polygon_vertex_indices: &'a [i32],
    pub uv_sets: &'a [FbxUvSet],
    pub normal_sets: &'a [FbxNormalSet],
    pub color_sets: &'a [FbxColorSet],
    pub tangent_sets: &'a [FbxTangentSet],
    pub binormal_sets: &'a [FbxBinormalSet],
    pub smoothing_layers: &'a [FbxSmoothingLayer],
    pub crease_layers: &'a [FbxCreaseLayer],
}

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

Borrowed FBX geometry, as expand_to_render_mesh and the writer consume it.

The borrowed counterpart of FbxMeshLayers plus the positions and indices those layers index into. Flat slices rather than a borrow of the owning struct so the reader can assemble one from decode locals before an FbxMeshInstance exists, and so it stays Copy.

A struct rather than a positional argument list because the list grows with every layer family the crate learns to read, and nine adjacent slices of nearly interchangeable types are easy to transpose silently.

Fields

control_points: &'a [[f32; 3]]

FBX control-point positions.

polygon_vertex_indices: &'a [i32]

Polygon-corner indices; a negative value terminates a polygon.

uv_sets: &'a [FbxUvSet]

UV layer elements.

normal_sets: &'a [FbxNormalSet]

Normal layer elements.

color_sets: &'a [FbxColorSet]

Colour layer elements.

tangent_sets: &'a [FbxTangentSet]

Tangent layer elements.

binormal_sets: &'a [FbxBinormalSet]

Binormal layer elements.

smoothing_layers: &'a [FbxSmoothingLayer]

Smoothing layers.

Scalars on a non-corner domain, so unlike the families above these do not reach FbxRenderMesh; they are carried for the writer.

crease_layers: &'a [FbxCreaseLayer]

Edge and vertex crease layers, carried for the writer as above.

Implementations

impl<'a> FbxGeometryLayers<'a>

pub fn from_instance(instance: &'a FbxMeshInstance) -> Self

Borrows every layer family from a decoded mesh instance.

pub fn new( control_points: &'a [[f32; 3]], polygon_vertex_indices: &'a [i32], layers: &'a FbxMeshLayers, ) -> Self

Borrows layers that are not (yet) attached to an instance.
