Eng.: All Topics Perspective Depth Extraction of Points on a Surface Under an Instantaneous Rigid Body Transformation http://link.aip.org/link/doi/10.1115/1.4005721 Per Bergstrom<br/> We consider the computational problem of finding the point in 3D-space on a transformed surface corresponding to a coordinate pair given in a perspective mapping. The transformation is a rigid body transformation that is assumed to be small and vary. Initially, it is unknown but when it becomes know ... [J. Comput. Inf. Sci.

Combining Variation Simulation With Welding Simulation for Prediction of Deformation and Variation of a Final Assembly http://link.aip.org/link/doi/10.1115/1.4005720 Andreas Pahkamaa, Kristina Warmefjord, Lennart Karlsson, Rikard Soderberg, and John Goldak<br/> In most variation simulations, i.e., simulations of geometric variations in assemblies, the influence from heating and cooling processes, generated when two parts are welded together, is not taken into consideration. In most welding simulations, the influence from geometric tolerances on parts is no ... [J. Comput. Inf. Sci. Eng. 12, 021002 (2012)] published Fri Feb 10, 2012. Reverse Shape Synthesis of the Hydropump Volute Using Stereo-Photogrammetry, Parameterization, and Geometric Modeling http://link.aip.org/link/doi/10.1115/1.4005719 Damir VuCina, Zoran Milas, and Igor Pehnec<br/> An automatic procedure for reverse 3D shape synthesis is proposed. Shape acquisition of an existing object involving stereo-photogrammetry, triangulation, and 3D reconstruction is applied to obtain the point clouds. Subsequent parameterization of the acquired geometry using mathematical surfaces yie ... [J. Comput. Inf. Sci. Eng. 12, 021001 (2012)] published Fri Feb 10, 2012.
