Based on moving least squares surface, the differential properties of each sample point on PSO are first evaluated. In terms of covariance analysis, the elliptical splat of sample point is then determined on its tangent plane. Finally, the splats are rendered from far to near by using elliptical weighted average filtering. According to the differential properties, moreover, the suggestive contours of PSG are attained so that non-photorealistic rendering of PSG is realized.

Harbin Institute of Technology, Harbin 150001, China)Abstract: The modified layers by O2-PBII technology on Ti6Al4V alloy surface were studied using X-ray photoelectron spectroscopy. The negative pulse voltage of 10, 20, 30 kV was applied to the sample, which was mounted on an oil-cooled sample holder. The results show that the thickness of the oxide layer increases with increasing implanted ion energy.
