Nyquist sampling function

Nyquist sampling function

A 2-dimensional Nyquist sampling function rendered using LandSerf's 3d viewer. The grid pattern was created by setting the Detail texture in the 3d viewer to Opaque grid. The function is based on a 2-d sinC function ((sin p x / p x)(sin p y / p y) ) which can be created in LandSerf using the polynomial generator when creating a new raster. Such functions can be used for spatial simulation and modelling.
