Fields

vertices: Vec<Vec3>

Validated vertex positions.

vertex_normals: Option<Vec<Vec3>>

Normalized supplied vertex normals, when present on the source mesh.

triangles: Vec<TriangleData>

Derived data for every input triangle.

bbox_min: Vec3

Component-wise minimum of all vertex positions.

bbox_max: Vec3

Component-wise maximum of all vertex positions.

diagonal: f64

Length of the axis-aligned bounding-box diagonal.

vertex_area_weights: Vec<f64>

One-third of each incident usable triangle’s area, accumulated per vertex.

source_metadata: Vec<SourceMetadata>

Validated source metadata copied from the input mesh.

degenerate_triangles: Vec<usize>

Indices of triangles rejected as degenerate.

Implementations

impl AnalyzedMesh

pub fn new( mesh: &Mesh, options: &MeshAnalysisOptions, ) -> Result<AnalyzedMesh, RecognitionError>

Validates mesh and constructs its analyzed representation.

pub fn all_non_degenerate(&self) -> Vec<usize>

Returns the indices of all triangles with positive analyzed area.

pub fn validate_selection(&self, ids: &[usize]) -> Result<(), RecognitionError>

Checks that a selection is non-empty, in range, and contains usable geometry.

pub fn validate_vertex_selection( &self, ids: &[usize], ) -> Result<(), RecognitionError>

Checks that a vertex selection is non-empty, unique, in range, and incident to usable mesh geometry.

pub fn selected_vertex_weights(&self, ids: &[usize]) -> Vec<(usize, f64)>

Returns area weights for vertices incident to the selected usable triangles.

pub fn selection_centroid(&self, ids: &[usize]) -> Vec3

Returns the area-weighted centroid of selected triangles.

Returns the zero vector when the selection has no positive-area triangle.

pub fn connected_components( &self, ids: &[usize], respect_features: bool, ) -> Vec<Vec<usize>>

Partitions selected usable triangles into edge-connected components.

When respect_features is true, traversal does not cross feature edges.
