% Generate vertices and faces for a planet with terrain.
Adds a height map to a sphere to produce a 3D terrain map.
theta needs to include 0 and pi. lambda should include 0 but not 2*pi.
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])
Type PlanetWithTerrain for a model of the moon using Clementine data.
