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.

OPTIONS

       --shapefile file.shp
              Path to the shapefile
