Detailed Description

allocate outdoor positions

Allocate positions outside of existing buildings using rejection sampling. This class extracts a random position in a box defined by the three RandomVariableStreams for the X, Y and Z dimensions (similarly to RandomBoxPositionAllocator), until a position is found that is outdoors with respect to all of the buildings in the scenario, or a maximum number of attempts is reached. The RandomVariableStream and the maximum number of attempts can be set using attributes. If the maximum number of attempts is reached, then the simulation aborts due to failure of properly positioning the node.
