This software requires matplotlib (>=1.5), and numpy (>=1.6).

This program can be installed by downloading the software and entering

python setup.py

within the main directory.

• 3d Terrain class
  • Grid of heights between 0 and 1
  • Addition and subtraction of Terrains, multiplication with scalar
  • Basic string representation
  • 2d and 3d graphical representations
    • Uses matplotlib for 3d, top-down greyscale for 2d
  • Saving and loading terrains (uses .terr format)
  • Voronoi diagram version of terrain
    • Regions defined by closest positions on 2d grid to points
    • Input set of points to make regions around
    • Can alter heights of all points in a region
    • Uniform randomly generated center points
    • Lloyd relaxation
    • Linear interpolation of heights of points to feature points within participant regions, predefined coefficients
      • Height of point += sum(coefficients[i]*distances_to_closest_feature_points[i] for i in range(len(coefficients)))
      • Can choose to add on heights from feature points or not
  • Terrain erosion
    • Thermal erosion
• Terrain generators
  • Diamond square algorithm
    • Takes noise color function (from frequency to amplitude)
    • Red, pink, white, blue, and violet preset noises
  • Perlin noise
    • Choice of grid size and size of grid squares
    • Choice of linear or cubic smoothing
  • Random Voronoi diagram (see above)
