The Reflection is a mirror image of the original object. We can differentiate 2D and 3D reflection by adding Z-axis. The Z-axis shows the depth of the surface. In the Reflection process, the size of the object does not change.

We can represent Reflection by using the following three ways-

  1. Reflection along with xy Plane: In the xy plane reflection, the value of z is negative.

x1 = x0

y1 = y0

z1 = z0

2. Reflection along with xz Plane: In the xz plane reflection the value of y is negative.

x1 = x0

y1 = -y0

z1 = z0
