我是品牌屁股new.js和webgl ...我試圖添加一個精靈（這是我自己的圖像）到這個旋轉球體。無論我在哪裏旋轉它，我都希望這個圖像在球體中保持不變，當然，球體中反射的環境仍然會移動。這是MC Escher繪畫「反光球中的自畫像」的一部分。一切似乎都工作正常，除非我不能讓精靈出現。儘管如此，它並沒有給我任何錯誤。哦，也是出於某種原因，天空盒環境最初不會加載。我必須點擊其中一個控件纔會出現。請幫忙！謝謝！這裏是我的代碼：將Sprite添加到旋轉球體

你可以把這個在jsbin或codepen或[你最喜歡的小提琴工具]？如果你不舒服張貼你的臉，也許是一個股票肖像圖像。使調試更容易。 – user01
@ user01我檢出了codepen，但無法找到要上傳圖片的地方。我錯過了什麼？ – lisabits
在這裏它被上傳到我的學校的服務器。您可以使用瀏覽器查看資源。 http://mcs.athens.edu/~lgeorge1/FinalProject/ @ user01 – lisabits
