Surface#
Aspect#
|
Calculates the aspect value of an elevation aggregate. |
Curvature#
|
Calculates, for all cells in the array, the curvature (second derivative) of each cell based on the elevation of its neighbors in a 3x3 grid. |
Hillshade#
|
Calculates, for all cells in the array, an illumination value of each cell based on illumination from a specific azimuth and altitude. |
Slope#
|
Returns slope of input aggregate in degrees. |
Terrain Generation#
|
Generates a pseudo-random terrain which can be helpful for testing raster functions. |
Viewshed#
|
Calculate viewshed of a raster (the visible cells in the raster) for the given viewpoint (observer) location. |
Perlin Noise#
|
Generate perlin noise aggregate. |
Bump Mapping#
|
Generate a simple bump map to simulate the appearance of land features. |
