Struct Relation 

pub struct Relation {
    pub original_id: i32,
    pub transform: Mat3x4,
    pub back_side: bool,
    pub has_normals: bool,
}

Transform relation between meshes.

Fields

original_id: i32

transform: Mat3x4

back_side: bool

has_normals: bool

True when this meshID’s contribution to properties_ slots 0..2 holds world-frame vertex normals (set by CalculateNormals at slot 0). Carries through Transforms and Booleans; exported as run_flags bit 1. Per C++ #1718.

Implementations

impl Relation

pub fn get_normal_transform(&self) -> Mat3

Normal transform: inverse-transpose of the 3×3 linear part. Multiply stored-property normals by this to get world-space normals. Matches C++ Relation::GetNormalTransform()

pub fn get_inverse_normal_transform(&self) -> Mat3

Inverse normal transform: transpose of the 3×3 linear part. Multiply world-space normals by this before storing in properties. Matches C++ Relation::GetInverseNormalTransform()

Trait Implementations

impl Clone for Relation

fn clone(&self) -> Relation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Relation

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

Formats the value using the given formatter.

impl Default for Relation

fn default() -> Self

Returns the “default value” for a type.
