Dust and rendering with fresnel







 A few examples of dust on different surfaces, the dust appears to reflect a lot in the light and from certain angles appears as a thin film that coats surfaces, there is some variation in the size of the particles on the wooden floor, but on the smoother surfaces like glass the dust appears to be more uniform and smaller in size. When the light is not reflecting from the dust particles the surface generally looks more dull with the colour being less vibrant. Also dust is usually accompanies by finger smudges and marks on more reflective surfaces.





Below are a few examples of dust on different surfaces and objects to show examples of the appearance with clean parts to show the difference in colour and texture when the surface is clean. Depending on the thickness of the dust layer it will alter the colour of the surface more than just a thin layer.
