他の立方体で構成された大きな立方体をレンダリングしようとしています ('10x10x10 合計 1000 立方体)。私のコンピューターと友人のコンピューターの 1 つは正常に動作しますが、別のコンピューターでは空白の画面が表示されます。私が使用しているサポートされている機能がないためだと思います。私はそれがどのような機能であるか、またどのように彼らがそれをサポートしていないことを伝えられるかを知りたいので、彼らに伝えることができます.
編集: 問題のあるコンピューターは、キューブのレンダリング以外のすべてを行っています。適切な背景色で完全に空白の画面が表示されます。
私はこれらすべてをクラスに隠しているので、関連する部分を提供しているだけです。
さらに情報が必要な場合は、お尋ねください。
