X3D and Ontological Space
In an X3D world, the emergent engine is the proximity sensor 
because it is a scalar identity of a location and locations 
organize the semantic tensor: the objects and methods of the 
spaces and the objects they contain.
The location organizes the ontology of the space. The distance 
organizes the relationships and force per related set. The 
distance is scalar by position and velocity. These values in 
a mapped space self-organize by the force per related set as 
afforded by the norms of the tensor set, or situation semantic: 
a spatio/temporally identified norm.
In an X3D world, events find you.
