The Billboard plug-in allows you to create
a special kind of symmetric geometry very suitable for real
time applications. This geometry is defined by one or more
rectangles each intersecting each other along their vertical
center lines. When you apply the same texture to each of these
intersecting polygons (front and back), you can create an
object that appears 3 dimensional from a distance using very
few polygons. Very often, modelers use this technique (with
a nice texture of course) to create extremely compelling trees.
A single rectangle version of such geometry is often referred
to as a "billboard". Billboards can be programmed in many
real time systems such that they always "face" the eyepoint.
In this way, you can maintain a realistic view of an object
using a single textured polygon in your application.
