Awkward flickering while using opengl_viewer

Thanks for sharing your code!

I have built the environment without any issue, and the results generated from cuda_renderer looks perfect to me. However, when I turn to use opengl_viewer, I found that some parts of the MPIs keep appearing and disappearing when I move my mouse, which causes annoying flickering. Do you have idea on what is happening? Thanks!

Is the flickering at the edges of the window? If so it's probably because the set of MPIs being used to render the new view switches as the new view pose moves around. The cuda renderer avoids this by reducing the field of view 20%.

Thanks for the reply! Yes but no, in most cases, the flicking happens on the edges of the window, but in some cases, it happens in the view. However, as those cases happen on the edges of some MPIs, I feel like it is possible due to the same rendering behavior you mentioned.

It seems like cuda rendering is more stable than OpenGL?
