Displacement mapping, bumb mapping, height map, global illumination, AWJ, microroughness

The paper presents a method of visualisation of surface microroughness acquired by hydroabrasive division (AWJ), by means of polygon representation. The method stems from theoretical and practical possibilities of so-called global illumination mapping of unevenness using suitable image maps. Based on data interpretation stemming from measurement of the surface roughness, an original method is proposed and realised, which also enables to visualise light interactions in the visualised microsurfaces.
