Expand description

One volume constraint of a pair (see SoftOverlapConstraint): the whole patch, or a cell of the multi-volume grid (Allard et al. 2010, section 5), as particle entries (particle, gradient) per side.

Fields§

§own: Vec<(u32, Vector)>

The own side’s entries: (particle, volume gradient).

§other: Vec<(u32, Vector)>

The other side’s entries: (particle, volume gradient); empty against a rigid collider.

§volume: f32

The signed volume estimate, sum depth |g| over both sides (negative: slack).

§normal: Vector

The contact normal, from the own side into the other (zero: degenerate).

§center: Vector

The area-weighted center of the bin’s vertices.

§enabled: bool

Whether the solver builds a constraint for it (the hook clears it to drop the constraint).

§impulse: f32

The impulse the solver applied through it at the last step (its multiplier along the own side’s gradients).
