To a tee

on 29 Oct 2022

% Create golf tee. Uses a logistic function to define radii

v=-5:.2:-.2;

r=min(1./(1+exp(-v))+.1,.42);

[x,y,z]=cylinder(r,50);

surf(x,y,z,EdgeC='n',FaceC='w')

% Create golf ball

% Uses demo='fiblat' which creates a sphere with dimples

% distributed in a Fibonacci lattice.

[~,~,h]=craters(dem='f');

h.surf.ZData=h.surf.ZData+1.9; % put ball on tee

% Change the light and ball colors

h.light2.Color=[0 .3 .2];

h.surf.FaceColor=[1 1 1];

% Add turf
