Path: Interplanetary/Ephemeris
% Generate vertices and faces for a planet patch with terrain.
Adds a height map to a sphere to produce a 3D terrain map.
scale exaggerates the surface variations from a sphere to make them
easier to see.
Rendering the planet is done with patch.
patch('vertices',v,'faces',f,'facecolor',[0.5 0.5 0.5],...
'facelighting','gouraud','linestyle','none');
axis equal
ambient = 0.2; diffuse = 1; specular = 0.0;
material([ambient diffuse specular])
This function will not handle the pole. use PlanetWithTerrain
for orbits that go over the pole.
p is an optional 3xn array of position vectors to be plotted.
Type PlanetWithTerrainPatch for a model of the moon using
Clementine data.
