为什么树莓派上的JavaFX（3D）无法正常工作，尽管它应该可以？

Question

我认为我已经阅读了所有关于在树莓派上使用JFx解决3D问题的可用解决方案，但以下方案都不符合我的需求。我在运行2D应用时没有任何问题。 但是当我尝试运行3D程序时，所有的3D元素都消失了。在运行此命令后：

java -Djavafx.platform=eglfb -Dprism.verbose=true -Dcom.sun.javafx.experimental.embedded.3d=true -Dprism.glDepthSize=24 -Dprism.forceGPU=true -jar Brake_Check.jar

I get this:

Prism pipeline init order: es2 sw

我已经安装了armv6hf-sdk-8.60.9

我将感激任何建议。

经过进一步的研究，我还添加了OpenJFX： apt-get install openjfx 这样整体上有了一些小的改进，但仍然缺少一些东西。 也许我会重新开始。我使用教程为我的树莓设置JavaFX，然后缺少libprism_es2.so，所以我从/usr/lib/jvm/jdk-8-oracle-arm32-vfp-hflt/jre/lib/arm/libprism_es2_eglfb.so复制并重命名它（我选择了这个，因为我认为如果我使用-Djavafx.platform=eglfb参数，这是一个好的选择），现在我添加了OpenJFX，那里还应该安装什么？你认为更新的sdk版本可能有帮助吗？但另一方面，我担心我在操作Linux方面的知识程度太基础了，所以我宁愿留在已经拥有的版本上，而不是取得进展。

现在，我的应用程序看起来像这样：

你还有其他的建议吗？

你是否在谷歌上搜索了“UnsatisfiedLinkError: com.sun.prism.es2.X11GLFactory.nInitialize([I)J”并查看了所有相关链接？ - Jim Garrison

我认为JavaFX版本不支持X11。你必须直接在终端上尝试。 - José Pereda

我已经编辑了我的帖子。 - Karol K

Answer 1

所以，解决我的问题的主要方法是安装apt-get install openjfx，我之前已经提到过了。之后，我不再需要使用-Djavafx.platform=eglfb。 接下来出现的问题是一切都是黑色的。问题似乎在场景中添加的光(PointLight)上。当我把它删除后，一切开始变得好多了，但是...仍然存在一些缺陷。盒子上没有阴影，antiAliasing不起作用，虽然只有一个简单的动画，但它很卡顿。

快速更新。 一切都正常工作，我已经在项目中恢复了灯光。 我所做的是更改RPi的高级设置。

sudo raspi-config 然后选择高级选项，接下来选择 GL Driver，然后选择 GL (Full KMS) OpenGL desktop driver with full KMS，保存并重新启动。

目标达成。
