我目前正在使用Artoolkit（C和C++語言軟件庫，可讓程序員輕鬆開發增強現實應用程序）和Maya2013開展項目。我想知道有沒有人能成功地從maya中導出VRML文件並將其顯示在artoolkit中。 wrl文件可以在cosmoplayer中查看，但是它們不適用於artoolkit。maya及其使用artoolkit的VRML導出
[1] 好吧，如果我簡單的寫
Shape {
appearance Appearance {
material Material { }
}
geometry Box { }
}
它具有的ARToolKit效果很好。
[2] 當我導出模型（即球體）時，它不起作用。這是它的wrl文件。
