Java3D Canvas3D在Win64環境中具有繪畫周期故障
[英]Java3D Canvas3D has paint cycle glitch in Win64 environment
問題描述
我有一個Java / Swing / Java3D / JOGAMP JOGL /應用程序，其中一組XYZ滑塊控制3D查看器的位置。 它在MacOS（10.11）上運行良好。 但是，在Windows 10（64位）下運行時，屏幕的3DCanvas區域有時會被空白灰色覆蓋。
我為Canvas3D使用黑色背景，並使用默認的雙緩沖。
有人建議使用簡約的應用程序進行測試，然后我使用Java3D.org中的“ PyramidEample.java”代碼示例復制了相同的問題（如下所述）
這是我在Windows-10（64位）中看到的內容：
1）在將應用程序圖標化到擴展塢，然后重新整理窗口（去圖標化）時，會發生錯誤。 當應用程序窗口膨脹時，您會在Canvas3D區域中看到一秒鍾的正確圖像，然后將其覆蓋或替換為純灰色（與滑塊控件的背景顏色相同）。
如果拖動滑塊，Canvas3D將繼續顯示3D內容。 在Swing鼠標處理程序處理了其中一個應用程序滑塊之后，我從未見過灰色的封面。
2）當我將應用程序窗口橫向拖離屏幕，然后反轉並向后拖動時，Canvas3D部分在正常圖像和淺灰色之間閃爍。 拖動結束時（應用程序完全封閉在屏幕中），最終的Canvas3D區域是不可預測的。...在釋放鼠標時，可以將其繪制為普通灰色或純灰色。
3）睡眠-不睡眠。 如果我的應用程序位於前台並睡眠Win筆記本電腦，則當我將其喚醒后，我的應用程序將在Canvas3D繪制位置顯示為淺灰色。 演示錯誤外觀的視頻剪輯
我試過的
1）雙重緩沖問題？ 我嘗試將Canvas3D設置為禁用雙緩沖，但沒有效果。
2）我將代碼放入應用程序的WindowListener的“ windowDeiconified（event）”方法中，該方法強制進行Canvas3D重繪，但是卻無濟於事。
3）由於該錯誤是與平台有關的，因此我嘗試了所有可能的“系統外觀”選項，但是並沒有解決問題。
由於一個非常簡單的測試應用程序會顯示3D圖形錯誤，因此如果您可以縮小到Java3D運行時環境變量的范圍，將有幫助：1）如果使用較舊的Oracle Java3D（JRE 1.8.0_22或更早版本）而不是JOGAMP 1.6.0替換堆棧，您看到vid中顯示的錯誤了嗎？
2）無論您運行什么Java3D堆棧，了解您是否可以看到此錯誤都是有幫助的。

對不起，這個舊的重播。
將以下內容添加到您的主類中：
static {
// in JRE 7 from causing redraw problems (i.e. the Java 3D canvas is sometimes
// drawn as a blank gray rectangle).
System.setProperty("sun.awt.noerasebackground", "true");
}
您的完整代碼，這次使用JFrame和Canvas而不是默認的SimpleUniverse的內部框架：
