meshlab - 无法在 headless 虚拟环境中运行 meshlabserver 过滤器

Question

我使用 sudo apt-get install meshlab 在 debian 9.4 上安装了 meshlab

首先在尝试转储过滤器列表时

sudo xvfb-run -a -s "-screen 0 800x600x24" meshlabserver -d filters

此日志失败

Loading Plugins:
Current Plugins Dir is: /usr/lib/meshlab/plugins 
Error in XMLFile: filter_measure.xml - line: -1, column: -1 - 
Error in XMLFile: filter_mutualinfo.xml - line: -1, column: -1 - 
Total 227 filtering actions
Total 13 io plugins
called here! 
Segmentation fault (core dumped)

并且在尝试运行过滤器时

sudo xvfb-run -a -s "-screen 0 800x600x24" meshlabserver -i original.obj -s /usr/lib/meshlab/plugins/filter_measure.xml

它失败并显示此日志

script /usr/lib/meshlab/plugins/filter_measure.xml
Loading Plugins:

我究竟做错了什么？

看起来尝试在 headless 模式下运行 meshlabserver 是一个远景……请参阅此处的评论:“有一些过滤器使用 [an OpenGL] 渲染上下文和 GPU(例如环境光遮蔽)，作为可批处理操作需要这些过滤器。这就是我们必须在 MeshLabServer 的初始化中包含渲染上下文的原因。我们没有针对此问题的“官方”解决方法。”

我认为您最好的机会是使用 X 运行它，而不是尝试使用 xvfb-run 使其在 headless 模式下工作......
