when I call the function engine.init(), some wrong message shows as the following:

I /think/ you have a version of Pi3d newer than 2.14 installed. There was a change in a later version of Pi3d that the the pypi and master branch release haven't been updated to work with.

The WIP SonyPSVR branch has a fix for it, but for simplicity sake you can you install Pi3d 2.14 ? e.g.:

sudo pip3 install pi3d==2.14

It works well. I can watch the scene from desktop, but i can't see the scene in the oculus rift cv1. Are there some problems with rendering? 2018-04-20 12:45:05,959 WARNING: pi3d.Display: Do you need to install pygame?

Although, I've never used a CV1 and can only suggest you try backing up your config.txt first before trying config_DK2.txt. So there's the possibility it doesn't work.

So, have you modified your /boot/config.txt as mentioned in the Install steps in the README?

Also, the 'HMD Device found, vendor=None, product=None, path=None` doesn't look promising for reading head rotation data.

What version of OpenHMD are you using on which OS platform are you running?
