Function slice_tet 

pub fn slice_tet(
    v0: Vec3,
    v1: Vec3,
    v2: Vec3,
    v3: Vec3,
    plane_origin: Vec3,
    plane_normal: Vec3,
) -> CellSliceResult

Computes the intersection of a tetrahedron with a slice plane.

Returns the intersection polygon vertices and interpolation data for computing attribute values at intersection points.

Arguments

• v0, v1, v2, v3 - Tetrahedron vertex positions
• plane_origin - A point on the plane
• plane_normal - The plane normal (points toward kept geometry)

Returns

A CellSliceResult containing 0, 3, or 4 vertices depending on the intersection.
