glx error in pointcloud visualization.

[Tejaswi Kasarla]

For visualizing pointcloud, I use this repo.

In draw_pcs_open3d function (after passing the geometries to it),

I get the following error while it tries to create a visualization window:

~/anaconda3/envs/pointpillars/lib/python3.7/site-packages/alfred/vis/pointcloud/pointcloud_vis.py in draw_pcs_open3d(geometries)
     46         return False
     47     vis = visualization.Visualizer()
---> 48     vis.create_window()
     49     for g in geometries:
     50         vis.add_geometry(g)

RuntimeError: [Open3D ERROR] GLFW Error: GLX: Failed to create context: GLXBadFBConfig

Any idea how to fix this error?

seems like a Glfw error,.have u install deps of open3d?

@jinfagang yes, I have installed all dependencies of open3d. Turns out that display server isn't set correctly. I have changed it.

Error on two machines so far:

RuntimeError: [Open3D ERROR] GLFW Error: GLX: GLX version 1.3 is required

I have GLX version 1.2 (checked on glxinfo). Is it necessary to have glx version 1.3 for open3d to work?

I will update an example code of visual 3d using alfred (though it might already have one), also provide dedicated deps of open3d. It will be some days due to China under plague of coronavirus we havn't start work day yet. Meanwhile I suggest u better upgrade GLX version, open3d homepage have their version requirements.

alfred has been updated with latest open3d API, you can checkout demo file examples/demo_3d_pointcloud.py for usage.
