# 3D Reflection

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-**

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

**x1 = x0**

**y1 = y0**

**z1 = **–**z0**

# Matrix of 3D Reflection-

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

**x1 = x0**

**y1 = -y0**

**z1 = z0**
