Here is a new section on conic sections, no pun intended.
Conic sections are intersections between a plane and a mathematical cone.
They are the common parabola, hyperbola, and ellipse, along with some other common geometric shapes. This new area of Zona Land illustrates how a plane and a cone intersect to form these shapes. The help page for VRML plug-ins has been cleaned up a bit. Information that was no longer needed has been removed, and the wording has been redone to, hopefully, make things very understandable. Virtual Reality Modeling Language, VRML, is a 3-D interactive medium for the Internet.
