pub fn triangle_barycentric3(
triangle: &Triangle3,
point: DVec3,
tolerance: Tolerance,
) -> Result<[f64; 3], BarycentricError>Expand description
Barycentric coordinates of point in a 3D triangle, as weights of
a, b and c.
A point off the triangle’s plane gets the coordinates of its orthogonal projection onto that plane: the weights reproduce the projection, not the point.
