Struct Signature 

pub struct Signature {
    pub version: i16,
    pub extents: [f64; 3],
    pub area: f64,
    pub volume: f64,
    pub closed: bool,
    pub triangles: u64,
    pub d2: Vec<f32>,
}

The shape signature of one mesh.

Fields

version: i16

extents: [f64; 3]

Oriented bounding box edge lengths, largest first (model units).

area: f64

Surface area (model units²).

volume: f64

Enclosed volume (model units³); reliable only if closed.

closed: bool

Watertight and consistently oriented.

triangles: u64

d2: Vec<f32>

D2 histogram, D2_BINS values that sum to 1.

Implementations

impl Signature

pub fn proportions(&self) -> [f64; 2]

Middle and smallest extent relative to the largest (scale-free).

pub fn sphericity(&self) -> Option<f64>

Sphericity π^⅓·(6V)^⅔ / A (1 = sphere), only for closed meshes.

pub fn is_valid(&self) -> bool

Plausible values (e.g. read back from the database).

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Signature

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&Signature> for SignatureSummary

fn from(s: &Signature) -> Self

Converts to this type from the input type.

impl PartialEq for Signature

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for Signature

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
