Struct Mesh 

pub struct Mesh {
    pub positions: Vec<Vec3>,
    pub normals: Vec<Vec3>,
    pub indices: Vec<u32>,
}

Owned triangle or line mesh generated from a built-in Geometry.

Each vector has independently allocated storage. Triangle primitives use counter-clockwise index triples when viewed from outside; Geometry::Line has exactly two indices and zero normals.

Fields

positions: Vec<Vec3>

Vertex positions in local metres.

normals: Vec<Vec3>

Per-vertex unit normals; line meshes use zero vectors.

indices: Vec<u32>

Zero-based indices into Self::positions.

Implementations

impl Mesh

pub fn validate(&self) -> Result<(), Diagnostic>

Validates this owned mesh for use with the procedural helpers.

pub fn translated(&self, offset_m: Vec3) -> Result<Self, Diagnostic>

Returns a copy translated by offset_m metres.

pub fn rotated_xyz(&self, radians: Vec3) -> Result<Self, Diagnostic>

Returns a copy rotated by XYZ Euler angles in radians.

pub fn scaled(&self, scale: Vec3) -> Result<Self, Diagnostic>

Returns a copy scaled per axis. Negative determinant scales reverse winding once so triangles remain outward-facing relative to their normals.

pub fn reversed_winding(self) -> Self

Reverses all triangle winding and negates each normal.

pub fn map_positions<F>(&self, map: F) -> Result<Self, Diagnostic>

where F: Fn(Vec3) -> Vec3,

Maps positions through a pure caller-supplied function and recalculates smooth normals from the resulting triangles.

Trait Implementations

impl Clone for Mesh

fn clone(&self) -> Mesh

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mesh

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Mesh

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Mesh

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Mesh

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
