Bio-Medical Demonstration
This demo takes advantage of the computational model contained in 3D R-tree structure for the automated implication of spatial relations. It makes use of boundary representation methodologies for the deduction of topological and directional relations between the spatially indexed records of a 3D R-tree instance. For the purposes of this demo, a bio-medical environment containing several intenal organs of the human body has been set up. Each internal organ is represented by a distinct 3D object which can be freely chosen in order to retrieve its spatial correlations with the rest of internal organs. The overall retrieval procedure is based on the artificial selection of the appropriate only relations, instead of the entire set of possible combinations between each record. It is worth mentioning that the directional relations correspond to the default position/orientation of the right-hand coordinate system used by X3D standard.
(1) Initialize a 3D R-tree data structure with scene's internal organs
(2) Display the generated 3D R-tree in X3DOM canvas (optional)
