REFLECTION

In 3D-reflection the reflection takes place about a plane whereas 2D reflection it used take place about an axis. The matrix in case of pure reflections, along basic planes, viz. X-Y plane, Y-Z plane and Z-X plane are given below:

Transformation matrix for a reflection through X-Y plane is:

Transformation matrix for a reflection through Y-Z plane is:

Transformation matrix for a reflection through Z-X plane is:
