Geometry instancing

Geometry instancing is a way of increasing the performance, or efficiency, of graphics on a computer. Basically, it means that instead of drawing the same shape, or object, over and over again, the computer creates just one copy of the shape and then copies it over and over again. This makes it much faster and easier for the computer to show the same shape multiple times. Think of it like a stamp: you don't draw the same shape every time, you just use a stamp to put the same shape in different places. That's what the computer does when it does geometry instancing.
