Struct DensityMassProperties 

pub struct DensityMassProperties {
    pub density: f64,
    pub mass: f64,
    pub surface_area: f64,
    pub volume: f64,
    pub centroid: Vec3,
    pub inertia: [[f64; 3]; 3],

}

Mass properties scaled to a physical density (Golovanov §8.11). The underlying FullMassProperties is a UNIT-density geometric result; here mass = density * volume and every inertia quantity scales linearly with density (inertia = density * geometric_inertia). The centroid and the principal AXES are density-independent; only the principal MOMENTS and the mass scale with density.

Fields

density: f64

Density used to scale the geometric (unit-density) properties.

mass: f64

mass = density * volume.

surface_area: f64

volume: f64

centroid: Vec3

Center of mass (identical to the unit-density centroid).

inertia: [[f64; 3]; 3]

Centroidal inertia tensor = density * geometric_inertia, row-major.

principal_moments: [f64; 3]

Principal moments = density * geometric_principal_moments, ascending.

principal_axes: [[f64; 3]; 3]

Principal axes (identical to the unit-density axes; density-invariant).
