A novel stereo displaying method is presented in this paper. According to the basic stereovision principle, the relationship between binocular disparity and 3d scene depth is discussed with matrix algebra in detail. With computer graphics considered, the horizontal binocular disparity of spatial point is converted to pixel disparity on screen. Then a spatial range condition of stereovision is introduced...
Topological relations are research focus in 3D GIS. Constructing nodes and arcs from curves, building the topological relations of these primitives with their parent geometry and other geometries, and forming the topological graph, are the basis of the calculation of topological relationship. The formal description and smallest set of topological relationships of 3D curves are given. The line segments...
