micro roughness, visualization, AWJ, displacement, bump mapping

This paper elaborates visualization of micro roughness of surfaces generated by hydro abrasive dividing. This visualization is outgoing from theoretical and practical possibilities so-called global illumination and bump mapping via competent image maps. On the basis of interpretation of issues resulting from surfaces roughness measuring an indigenous method is designed and executed. This method is used for depiction of micro roughness through polygonal representations and allows visualization of the light interactions on the visualized micro surfaces, too. This method is based on the physical relevant methodology of micro roughness visualization. It is considerably extending current potentialities of comparative analysis, mainly in light-propagation respect area with material and optical features of micro surface.
