Now we can make textured materials by replacing the vec3 color with a texture pointer:

where you used to have

new lambertian(vec3(0.5, 0.5, 0.5)))

now you should replace the vec3(...) with new constant_texture(vec3(...))

new lambertian(new constant_texture(vec3(0.5, 0.5, 0.5))))

We can create a checker texture by noting that the sign of sine and cosine just alternates in a regular way and if we multiply trig functions in all three dimensions, the sign of that product forms a 3D checker pattern.
