The three dimensional graphic tools from MATLAB are also extremely useful and powerful. Many of the 2D functions have their counterpart here and is usually called by appending a 3 to the end of the 2D function - for example (plot, plot3; quiver, quiver3 etc.). Once again we will see only a useful subset of the graphing features.
There are typical three uses for 3D graphics
Image processing is included in this chapter even through the image is a 2D. The color distribution on the plane make it a pseudo 3D processing.
