Demonstration, Interactive
Explore cross sections of different geometric solids: cone, double cone, cylinder, pyramid, and prism. Manipulate the cross section with slider bars, and see how the graphical representation changes.
Many cross-section interactives only deal with uniform cross sections. This interactive allows you to show the non-uniform cross-sections of shapes that are not prisms.
