3 Dimensional Translation in C program CS1355-Graphics & Multimedia Lab

3 dimensional transformation it has three axis x,y,z.Depandting upon there coordinate it will perform there Translation ,Rotaion,Scaling, The translation can be performed by changing the sign of the translation components Tx, Ty, and Tz.
