Fields

id: String

Unique identifier.

instance: usize

Instance index.

position: Point3<f64>

Position (bottom-left-front corner).

dimensions: Vector3<f64>

Dimensions (width, depth, height) after orientation applied.

mass: Option<f64>

Mass of the box (optional).

cog_offset: Option<Vector3<f64>>

Implementations

impl PlacedBox

pub fn new( id: impl Into<String>, instance: usize, position: Point3<f64>, dimensions: Vector3<f64>, ) -> Self

Creates a new placed box.

pub fn with_mass(self, mass: f64) -> Self

pub fn with_cog_offset(self, offset: Vector3<f64>) -> Self

Sets the center of gravity offset from geometric center.

pub fn center(&self) -> Point3<f64>

Returns the geometric center of the box.

pub fn center_of_gravity(&self) -> Point3<f64>

Returns the center of gravity.

pub fn bottom_face(&self) -> (Point3<f64>, Point3<f64>)

Returns the bottom face AABB (z = position.z).

pub fn top_face(&self) -> (Point3<f64>, Point3<f64>)

Returns the top face AABB.

pub fn volume(&self) -> f64

Returns the volume of the box.

pub fn base_area(&self) -> f64
