Erosion

< The Aleph : Grid >

Erosion Code Modified

The basic function of the Erosion Model is to show a field in which a grid is programed based upon a //height// or //vertical accumulation// of numerical values. These values aggregate based upon a simple mathematical formulae which allows the observer to locate a "hill" or highest numerical value at a point within the grid which gradually decreases based upon distance from that point. In order to run the simulation, the program calculates at random, points which are designated //rain-drops// and requires that each //drop// or agent move to an adjacent //patch// that possesses a lower numerical value, or lower //elevation.// As a result, the previous //patch// has its numerical value lowered, while raising the value of the //patch// which is receiving the agent. This allows for a gradual emergence of flows within the field. A schematic simulation of a basic principle involved in the phenomenon of Erosion.

As an initial investigation, the group set out to establish //multiple points of accumulation//, or "hills". In the process it was discovered that the mathematical formula involved to generate the single "hill" in the original program, allowed for not only a multiplicity of hills to be placed, but through a simple manipulation of the formula, that of valleys as well; or more correctly, to generate aggregations of high or low numerical values by the field of operation.

The numerical values are represented from lightest to darkest - highest to lowest.
