Matplotlib Examples

The following examples are based on examples in the 3D plotting Gallery of Matplotlib. This set of examples compare the methodology of forming 3D visulizations between Matplotlib and S3Dlib.

Matplotlib. Initially, x,y,z coordinates are constructed. The coordinates are then passed to specific Axes3D methods, eg. plot, plot_wireframe, plot_surface, plot_trisurf, contour, etc.

S3Dlib. First, base 3D objects are instantiated ( surface, line, or vectors ) to established the network relationship among the vertex coordinates. Functions are then used to map coordinates and colors to produce the final object. Mutliple mapping operations may be performed on the same object and objects. Additionally, objects of the same class may be added together to form one object. Finally, objects are added to the Axes3D.
