How to use pyrender.Viewer under SSH? #196

Open HaFred opened 3 years ago

HaFred commented 3 years ago

For SSH, seems like the only way is to do the rendering with a visualizer is offscreen rendering. However, I need to do viewer = pyrender.Viewer because I need to do viewer.render_lock.acquire(), whereas the pyrender.OffscreenRenderer class does not have it for me. So I am wondering is it possible to keep using viewer = pyrender.Viewer, while using a headless server with SSH?
Thank you!

I tried to follow the osmesa installation here. But errors as:

$ ./configure --prefix=/home/zhongad/Downloads/mesa_installation/
configure: error: Direct rendering requires libdrm >= 2.4.75

and to install libdrm I had:

$ sudo apt-get install libdrm-dev

In fact I have installed all these dependencies... Is it possible to install and use osmesa for pyrender under Ubuntu 20.04? @mmatl Thank you very much!
