Struct OffsetSample 

pub struct OffsetSample {
    pub source: Vec3,
    pub normal: Vec3,
    pub point: Vec3,
}

One evaluation of the offset: the source point, the unit normal the offset rides, and the offset point itself.

The normal is also the offset surface’s own normal wherever the offset is regular — it flips only past the evolute, which is what thicken::ensure_offsets_regular (the kernel’s only curvature gate) exists to refuse. This struct deliberately carries no other derivative data: the five consumers were audited and not one of them uses S_u/S_v for anything but the normal, and the blend march’s Jacobian is finite-differenced on the residual rather than assembled from partials.

Fields

source: Vec3

S(u, v) on the source carrier.

normal: Vec3

The unit normal, in the requested orientation.

point: Vec3

source + distance · normal.
