A Procedural, Minimal Input, Natural Terrain Plug-in for Blender

This paper uses methods of terrain representation, creation and realism described in literature. In particular a combination of terrain synthesis using Fractional Brownian Motion, and erosion procedures is examined, as well as the procedural formation of rivers via squig curves. Other techniques are examined, such as Triangulated Irregular Networks and ridges generation are discarded in terms of this project for reasons detailed. We find that using a combination of Fractional Brownian Motion, procedural formation of rivers via squig curves to form initial terrain, and hydraulic erosion for post processing, we have full control over the style of terrain: from jagged, mountainous regions to flat regions; and the phase of river from tightly rock controlled to flood plain regions.
