Yellow and white flashings w/ D435

Hi @juniorxsound ,

Thank you for your suggestions. I solved the GLFW issue by installing GLFW on my machine before. I received the D415 camera today but it still not worked.... I tried to debug it but I failed to find anything wrong. Maybe I need to use a newer machine.

Thanks!

I think this could be related to the USB bus on your MBA 2015. It is not USB 3.0 right? I also wonder if that happens when using the Intel Realsense Viewer that comes in the SDK

Thank you for your quick reply. Sorry that I forgot to mention the camera works well with the Intel Realsense Viewer. And I think the USB bus on MBA 2015 is USB 3.0. Thanks!

Could you please provide the firmware version of your D415 and D435? Maybe the old SDK you use does not support the newest firmware. Thanks!

Hi @tangbao was able to build and run this on MBP 2018 (Mojave 10.14.6) and run successfully with a D415

One quick caveat I did catch is it failed CMak'ing the project due to a librealsense GLFW issue so had to turn off the visual examples when using CMake - cmake ../ -DBUILD_GRAPHICAL_EXAMPLES=Off

Thanks @juniorxsound ! Have you tried it with D435?

[juniorxsound]

Unfortunately I do not have one, so can't really test it but if you want to dive into the code and try to debug that the librealsense pipeline initialization happens here

Hi @juniorxsound

I tried on an MBP 2017 today and it worked perfectly both with D415 and D435.

Now I am playing with your depth-player now. It seems that it needs some tricks (like adjusting the angle of camera and the size of window in OBS) to let the player get a good rendering result. Also, the streaming thing does not work now because the XMLHttpRequest is banned by CORS policy. I will look into this problem tomorrow.

One more thing -- the 3D hologram is generated based on 3D mesh, not point cloud, right?

Thank you for your time so much.

@tangbao Correct, it starts with a fully tesselated grid and displaces it using the depth map
