Gram-Schmidt: Subtract the Projection

0:50Fortellerstemme
0:00 / 0:00

Gram-Schmidt orthogonalisation — keep v₁ as u₁; subtract the projection of v₂ onto u₁ so what's left (u₂) is perpendicular; normalise to get an orthonormal pair. The same recipe extends to 3D by subtracting both shadows in turn.
