HAT(3D)

NAME
hat - generate test data for graph3d

SYNOPSIS
hat <grid-points> <radius>

DESCRIPTION
Hat produces a surface which looks like a hat. This is good graph3d(3d). The surface is a N by N grid, there will be n hills, of height h (default 6), and seed (default pid) can be used to initialize the random number generator. The output of hills is an example the type of input that surface(3d) can accept, and provides useful test-data for playing with graph3d(3d).

EXAMPLE
hat 60 20 | surface -unit | graph3d-tek
hat 60 20 | surface -unit -poly | graph3d -ps -hide | pswrap | lpr -Pps
hat 60 20 | surface -unit | graph3d -plot | <your favourite plot(1) filter>
