[Other resource] VolumeFog DL : 0: The Volume Fog sample shows the per-pixel density volumetric rendering technique. The fog volume is modeled as a polygonal mesh, and the density of the fog at every pixel is computed by subtracting the front side of the fog volume from the back side. The fog is mixed with the scene by accumulating an in/out test at every pixel -- that is, back-facing fog polygons will add, while front-facing ones will subtract. If the value is non zero, then the scene intersects the fog and the scene s depth value is used. In order to get better results, this demo uses 12 bits of precision by encoding high and low bits in different color channels.
