WebGLRendererで描画するよ。
SphereGeometry, MeshPhongMaterial, Mesh を使ってみたよ。 :bouzu:
さらに、DirectionalLight も使ったよ。 :cake:
んでもって、ImageUtils, Texture も使ったりして。 :beer:

地球表面の画像(1024*512)をJPGで、雲の画像(1024*512)を透過PNGで用意。
さらに、凹凸用の画像(1024*512)をJPGで用意。
:check: 「Planet Earth Texture Maps」の画像を使わせていただきました。
SkyBox用の画像は、こんな感じ。
[修正] (14/12/09 Tue 13:00)
背景の設定を変更。カメラの far の値も変更。
[修正] (14/12/27 Sat 21:23)
HTML記述を変更。
