NAME
osgearth_sharedlayer - demonstration of shared layers
SYNOPSIS
osgearth_sharedlayer --shapefile file.shp
DESCRIPTION
osgearth_sharedlayer is a sample program which demonstrates the use of shared layers. A
shared image layer is one that becomes available to other image layers during the
rendering phase. Thus if you share a layer, you can access it in a customer shader and
use it to modulate another layer.
In this example, we render a masking layer from a shapefile using the rasterization
(agglite) driver. We don't draw this layer directly; instead we use it as a mask and use
that mask to modulate the imagery layer from a custom shader, drawing random colors where
the mask exists.
