This paper presents a novel method of contour reconstruction from dexel data solving the shape anomalies for the complex geometry in virtual sculpting. Grouping and traversing processes are developed to find connectivity between dexels along every two adjacent rays. After traveling through all the rays on one slice, sub-boundaries are connected into full boundaries which are desired contours. The...
The virtual product data model in its different stages is an essential prerequisite for the virtual modeling of processes and their virtual simulation. Product design starts with conceptual design including the concepts for the future productpsilas shape and function - the gestalt. In this stage, the designers work on fuzzy product data interpreted in so-called scribbles and applied to perception...
This paper describes a new method to extract most of the noise points by combining the ellipsoid criterion with the Fuzzy C-Means clustering algorithm. The point cloud data are unorganized and without any normal or orientation information. Firstly, we determine if one point is the noise or not by the ellipsoid criterion. After acquiring new point sets being less noisy, we delete large-scale noise...
