Struct SoftBodyCell 

pub struct SoftBodyCell {
    pub vertices: [u32; 4],
    pub rest_volume: f32,
    pub stiffness_scale: f32,
    pub tear_resistance: f32,
    /* private fields */
}

A simplex cell of a soft body: a triangle in 2D, a tetrahedron in 3D.

Fields

vertices: [u32; 4]

The cell’s particles, positively oriented (positive signed area/volume at rest).

rest_volume: f32

The signed area (2D) or volume (3D) of the cell at rest.

stiffness_scale: f32

Multiplier of the material’s Young modulus for this cell (default 1.0): per-region stiffness, usually set through crate::dynamics::SoftBody::set_cluster_stiffness_scale.

tear_resistance: f32

Multiplier of the material’s tear strain for this cell (default 1.0), see crate::dynamics::SoftBody::set_cell_tear_resistance.

Implementations

impl SoftBodyCell

pub fn plastic_stretch(&self) -> Matrix

The accumulated plastic stretch of this cell’s rest shape (material frame, unit determinant): its current rest shape is this stretch applied to the shape it was created with (see SoftBodyMaterial::plastic_yield); the identity before any flow.

pub fn stress(&self) -> f32

The largest tensile strain of this cell as a fraction of its tear threshold, smoothed over the material’s SoftBodyMaterial::tear_smoothing: 0.0 slack, 1.0 tearing. Stays 0.0 while the material has no tear_strain (cells only tear on their strain).
