# 3D Plot - (Graphic Tools)

### Computer graphics are better for understanding  many types of data

 In these sections you can find many step-by-step commented guides to easily develop 3D plots. If you are not familiar with tridimensional graphics in Matlab, I recommend you start from Part 1; otherwise, go to the link of your interest. Part 1 (view, grid, subplot) Matlab provides many powerful instructions for the visualization of 3D data.

The instructions provided include tools to graph wire-frame objects, 3D curves, surfaces...

Part 2 (meshgrid, plot3, meshc, surfc)
The 3D graph functions intended for plotting meshes and surfaces 'mesh' and 'surf', and their several variants 'meshc', 'meshz', 'surfc', and 'surfl', take multiple optional input arguments...

Part 3 (sphere, plot3, mesh)
In this part, we demonstrate the use of the function 'sphere'. We are going to draw a unit sphere centered at the origin and generated by matrices x, y and z, of size 31 x 31 each...

Part 4 (meshgrid, figure, contour3, mesh, surfc, and surfl)
In this example we make a summarization of the use of the following 3D plot instructions: meshgrid, figure, contour3, mesh, surfc, and surfl.

Pie Charts
In the expression 'pie3(V, explode, labels)', 'explode' specifies whether to separate a slice from the center of the pie chart. V(i,j) is appart from the center of the pie chart if explode(i,j) is nonzero...

3D Animations
We’re going to experiment with simple animation in 3D. We are going to work with a sphere and are going to rotate our view angle. In the second experiment, we’re going to draw a paraboloid, change its size and rotate...

Summary of 3D Graphics
There are many facilities for visualization of 3D information or data (x, y, z). The facilities include built-in functions for plotting wire-frame objects, space-curves, shaded surfaces...

Solids of Revolution
Define a profile and revolve it about the x-axis. Use the cylinder function...

3D Polygons
Draw several faces to create or model a box...
