Struct FullMassProperties 

pub struct FullMassProperties {
    pub surface_area: f64,
    pub volume: f64,
    pub centroid: Vec3,
    pub inertia: [[f64; 3]; 3],
    pub principal_moments: [f64; 3],
    pub principal_axes: [[f64; 3]; 3],
}

Fields

surface_area: f64

volume: f64

centroid: Vec3

Volume centroid (unit density center of mass).

inertia: [[f64; 3]; 3]

Inertia tensor about the centroid for unit density, row-major [[Ixx, Ixy, Ixz], [Ixy, Iyy, Iyz], [Ixz, Iyz, Izz]].

principal_moments: [f64; 3]

Principal moments of inertia (eigenvalues of inertia) at unit density, sorted ASCENDING: principal_moments[0] <= [1] <= [2]. Golovanov §8.11.

principal_axes: [[f64; 3]; 3]

Principal axes of inertia (eigenvectors of inertia), one per row: principal_axes[i] is the unit axis whose moment is principal_moments[i]. The three axes are orthonormal and arranged as a RIGHT-HANDED frame (determinant +1); the sign of the third axis is fixed to enforce handedness. Density-independent.

Implementations

impl FullMassProperties

pub fn with_density(&self, density: f64) -> DensityMassProperties

Scale the unit-density geometric result to a physical density (Golovanov §8.11): mass = density * volume, inertia and the principal moments scale by density, while the centroid and principal axes are unchanged. Panics only on a non-finite density is avoided — callers should pass a finite, positive density; a zero density yields a massless (all-zero inertia) result, which is well defined.
