Abstract. Topological relationships between spatial objects in the twodimensional space have been investigated for a long time in a number of disciplines like artificial intellige...
Moving objects databases managing spatial objects with continuously changing position and extent over time have recently found large interest in the database community. Queries ab...
When an observer is in a 3D scene, a topological change in the view arises when the line of sight is tangent to four objects. If we consider polyhedral scenes, the relevant lines ...
