Description
|
|
|
|
Amplify Impostors is a small but powerful tool that allows the creation of different
|
|
types of Impostors, which are substitutes of complex high polycount objects made from flat
|
|
and simple polygons, that render a fake version of the original object (hence the name).
|
|
Much like traditional sprites, they usually consist of a single flat quad polygon or simple
|
|
polygonal shapes and, like classic billboards, always face the camera. Think of them as a
|
|
camera facing cardboard version of the object you want to render. The common purpose of
|
|
using such technique is to be able to represent far distant objects with a very low
|
|
polycount, for instance, trees, bushes, rocks, ruins, buildings, props, etc.
