运行 Hausdorff 距离和按顶点质量着色不导出颜色和质量
Running Hausdorff distance and colorize by vertex quality doesnt export the color and quality
我是来自 meshlabserver 的 运行 Hausdorff Distance 过滤器，我想保存带有顶点着色的采样网格。
计算了距离，我在 shell 输出和日志文件中得到了它。
将输出导出到 *.ply 时，我没有得到顶点质量和颜色。
我是运行以下命令：
meshlabserver -i first.stl -i second.stl -o out.ply -m vc vq -s script.mlx
其中 script.mlx 包含以下内容：
<FilterScript>

当 运行 从 GUI MeshLab 按顶点质量进行 Hausdorff 距离和着色并导出到层时，我得到具有质量和颜色的网格。
是否可以从 meshlabserver 获得相同的行为？ （即使只获得顶点质量也会很好）
我错过了什么吗？
谢谢 :)
我用我自己的两个网格完成了与您相同的步骤。第二个网格由 Quadric Decimation 过滤器和几个应用于机翼区域的 Taubin Smooth 过滤器生成。
当我 运行 你的 script.mlx 在 meshlabserver（pre-release 版本）中使用相同的命令时，我有这个日志：

我的输出文件具有预期的颜色和质量。由于我的额外平滑，机翼中的距离大于 body（蓝色表示更大的距离，如质量直方图所示）。
我的电脑一切正常，你的有什么问题吗？...我使用 2016 的 meshlab 服务器下载了官方 2016-12 版的 meshlab 和 运行 相同的脚本。这是结果：
作为您的输出：无颜色，每个质量值设置为零。但是，等等... 这看起来像原始的 50k 型号，而不是预期的大减价型号。 Meshlabserver-2016 正在保存第一个网格，而不是第二个网格。
所以我后运行ged 你的 script.mlx 文件在网格 0 而不是网格 1 上采样
