D3 Globe with Canvas, WebGL, and Three.js

D3.js comes with a lot of geographical projections and there are many cool demos that let you explore different ways of visualizing a map of our earth. I really like the orthographic projection as it gives you a perspective (or azimuthal) projection where earth is a sphere or globe as it appears from outer space. D3 already has some great examples of this projection, and I have also made my own basic D3 Globe with very little code. But today, I want to expand on this concept and try to incorporate an image of the earth into the globe projection to create a more realistic view of earth. First, I will attempt to make this happen with just HTML5 Canvas and then I will explore other technologies like WebGL and Three.js to make the globe more responsive.
