Three Dimensional Transformation Algorithms in c Language Programming

These 3d dimesional Transformation algorithm was draw by the mathematical calculation using sin and cos function in Math.h header file using bar3d function in Graphics header file.And it will perform After the scaling Operation in x-axis y-axis z-axis.In these three dimensional it show the translation effect
