Witryna4 cze 2024 · The results show that surface roughness values measured using a sensor well agree with the model output. For ground and milled surfaces, the correlation coefficients obtained are high, while for the surfaces generated by shaping, the correlation coefficient is low. It is observed that the sensor can effectively assess the … Witryna14 sty 2024 · Using the Roughness Slider. While Specular and Metallic help to determine what material an object's surface acts like, Roughness helps to determine the actual look of the material. Roughness, like the other values, ranges from 0-1, with 0 being glossy, and 1 being rough. Rougher surfaces show dispersed, less visible …
