My Question

Hello all,

First of all, thanks all for this awesome library. Recently, I am working on open3d GUI as a 3d point cloud processing tool. But when trying to save the scene as an image (ex. screenshot), as far as I know, there is no such feature to include "3d_label" into the image that I want to save together.

In documentation, the 3d_label is added by the scenewidget class. And point cloud is added as a geometry by the renderer (Open3DScene) of the scenewidget. In terms of the screenshot, "render_to_image" function can be used. But this function is only in the renderer, not scene widget.

Is there a way to save the point cloud and 3d_label togrether as an image ?

Thanks in advance.

Below is the current working environment info.

• Open3D version: 0.15.1
• Python version: 3.7
• OS: Windows / Ubuntu

hello, do you know how to solve this question now?

Hello, @danter1995 .

Unfortunately, I couldn't figure it out yet. It might be possible if the 3d label is made up with another point cloud geometry. However, this should be the very last option to solve this issue because this is such a burden job, and this is not fancy at all...

@JunhyeopLee Have you already found a solution?. I'm using open3d 0.17.0 and the problem persists.
