    通過修改scenceview.js中tileBackground和defaultTileBackground中的png的base64編碼就可以達到要求。

4.8中通過修改scenceview.js

e.DEFAULTTILEBACKGROUND = typeof dojoconfig!=undefined &&dojoconfig.bg!=undefined?dojoconfig.bg:"原來的base64"

在html中引用init.js前

傳入圖片base64編碼，這樣三維球就可以按照我們想要的顏色渲染，圖片分辨率最好是標準的2x2 4x4 8x8 16x16 32x32 64x64 128x128 256x256。
