In this animation: We start with the standard cube formed by the unit vectors î, ĵ, k̂, shown as yellow arrows. These vectors form the edges of a perfect cube. The determinant of the identity matrix is ​​1 → the cube has volume. We then apply a matrix whose determinant is zero. Notice how the cube collapses! The transformed vectors still form a region, but it loses depth:
